Yale Assure Lock SL Key Free Touchscreen Deadbolt with Yale Home Module - Satin Chrome

The Yale Assure Lock SL is a 100 per cent key free touchscreen deadbolt for standard timber, fibreglass and aluminium entry doors. There is no keyway and no cylinder anywhere on the lock: entry is by PIN code on the capacitive touchscreen, or from your phone through the Yale Home App over Bluetooth. The app is a free download on both Android and iOS with the same features on each. The Australian HK build ships with the Yale Home Module and DoorSense door position sensor already in the box, so the smart features work from the moment it is fitted.

Mechanically it is a conventional adjustable-backset deadbolt. It suits the standard Australian single-bore preparation - a 54mm cross bore and a 25mm edge bore - at either a 60mm or a 70mm backset, on doors from 35mm to 57mm thick. If your door already carries a deadbolt, the Assure Lock SL drops straight into the existing holes with a Phillips screwdriver. See Chapter 02 for backset measurement before ordering.

Because the lock has no mechanical override, it is best specified where the dwelling has another way in. The two callouts below are the two things worth reading before you buy. Everything else - codes, app control, remote access and voice assistants - is covered in the FAQ and the dedicated FAQ tab.

Dispatch
Estimated Dispatch
Usually ships the same business day when ordered before 11am AEST, excluding Queensland public holidays. See Shipping & Returns for delivery timeframes.
No key override
No mechanical key override
This model has no keyway and no key. Yale states in both printed manuals that, because there is no mechanical override, the lock should be used where the dwelling has additional entry points. A flat battery is recovered with a 9V battery held to the terminals under the keypad, not with a key. If you want a keyed deadbolt on the same door preparation, the Yale Assure Lock Keyed is the identical lock with a C4 cylinder added. Further reading: locks without a key override.
Not weather rated
Not weather rated - sheltered entry doors only
Yale publishes no IP rating for the Assure Lock SL and states plainly that it is not suitable for entry points where the escutcheon is exposed to outdoor elements. It is not for gates, unroofed doorways, carport doors or anywhere the keypad takes driving rain or direct sun. Both escutcheons are interior-grade housings.

Key Features

  • 100 per cent key free. No keyway to pick, bump, drill or lose a key for. Entry is by PIN, app or Apple HomeKit.
  • Capacitive touchscreen keypad. Wakes on a press of the Yale logo, then lights the numerals. One touch of the logo throws the deadbolt on the way out.
  • Yale Home Module and DoorSense included. The Australian HK build ships with the Bluetooth Yale Home Module (YD-MD01) and the DoorSense sensor, so app control, Auto-Unlock and door position sensing work out of the box. Background: Yale network modules explained.
  • Works with Android and iOS equally. The Yale Home App is a free download on Google Play and the App Store, with the same entry code management, guest access, activity trail and Auto-Unlock on both. Nothing on this lock is phone-brand dependent.
  • Auto-Unlock on approach. Geofencing plus Bluetooth unlocks the door as you walk up, without taking the phone out of your pocket. Available on both platforms.
  • Smart home ready. Apple HomeKit pairs directly at the lock with no hub. Google Home, Amazon Alexa and Samsung SmartThings are added by the optional Connect Plus Hub 2, and work from any phone.
  • 24/7 activity trail. Every entry is logged in the Yale Home App, per user, as it happens.
  • DoorSense door position sensing. Tells you whether the door is actually closed, not just whether the bolt is thrown.
  • Adjustable 60 or 70mm backset. One deadbolt covers both standard Australian backsets - no separate part number.
  • Automatic handing. The lock hands itself on first power-up. Nothing to specify at order and nothing to reverse on site.
  • 9V emergency power. Hold a 9V alkaline to the contacts under the keypad to wake a flat lock and enter your code.
  • ANSI/BHMA A156.36 Grade 2 certified and RCM compliant for Australia and New Zealand.

Access Methods

Greyed rows are methods this lock does not support. They are listed so you can see at a glance what is and is not available. For a plain-English comparison of credential types, see Chapter 03 - Access Methods.

Method Available Notes
PIN Code Yes Entry codes of 4 to 8 digits created at the keypad, or 4, 5 or 6 digits created in the Yale Home App.
Yale Home App Yes Free on Android and iOS, with identical features on both. Lock, unlock, manage entry codes, share access and read the activity trail over Bluetooth at the door.
Apple HomeKit Yes Pairs directly at the lock over Bluetooth, no hub required. Siri control on iPhone, iPad and Apple Watch.
Google Home With Connect Plus Hub 2 Add the optional Hub 2 gateway for Google Home control and routines. Works from an Android or an iOS phone.
Alexa and SmartThings With Connect Plus Hub 2 Amazon Alexa and Samsung SmartThings, both enabled by the optional Hub 2 gateway. Phone brand makes no difference.
Mechanical Key Not Available No keyway and no cylinder. This is a deliberate 100 per cent key free design.
Fingerprint Not Available No biometric reader on this model. See the Yale ByYou Pro, Kyra Pro or Luna Pro+ for fingerprint.
RFID Card or Key Tag Not Available Yale Contactless Key Tags pair to the Unity series only, not to Assure.
Face Recognition Not Available Face recognition is a Yale Luna Pro+ feature.
Built-in Wi-Fi Not Available Remote access needs the Yale Connect Plus Hub 2, sold separately.

Yale Home App and Smart Home Integration

The Yale Home App is a free download on Google Play and the App StoreiOS App StoreAndroid Google Play and is the control surface for everything the Home Module adds: entry code management, guest access, the 24/7 activity trail, Auto-Unlock, Auto-Lock and DoorSense alerts. The app is the same on Android and iOS. No feature on this lock is reserved for one phone brand, and Auto-Unlock works on both.

Beyond the app, the lock joins a smart home by two routes. Apple HomeKit pairs directly to the Home Module over Bluetooth, so Siri and the Apple Home app work at the door with no extra hardware, though remote HomeKit control still needs your own Apple home hub. Google Home, Amazon Alexa and Samsung SmartThings all work through the optional Connect Plus Hub 2, which also delivers remote access to Apple households. Compare the ecosystems in Chapter 15 - Smart Lock App Platforms and in Which Smart Lock Platform Is Right for You.

Android or iPhone - what actually differs
Very little. The Yale Home App, every entry code function, guest access, the activity trail, DoorSense alerts and Auto-Unlock are identical on both platforms. The single genuine difference is that Apple HomeKit pairs at the lock without a gateway, while Google Home, Alexa and SmartThings need the Connect Plus Hub 2. Add the Hub 2 and the two platforms are level, since Apple households need a home hub for remote access anyway. If you run Android, this lock is a perfectly ordinary choice.
Set the app up before you hand out codes
Entry codes created at the keypad before the lock is paired to the Yale Home App stop working once pairing completes. Create codes in the app from the outset. Codes made in the app are also the only ones that appear in the activity trail. This is the single most common Assure support call, on either platform.

Remote Access, Alexa and Google

The Assure Lock SL has no built-in Wi-Fi. Adding the Yale Connect Plus Hub 2 - a plug-in 2.4GHz gateway, sold separately - extends the lock beyond Bluetooth range and enables:

  • Lock, unlock and manage entry codes from anywhere
  • Real-time notifications for entry, door ajar and low battery
  • Amazon Alexa, Google Home and Samsung SmartThings voice control
  • DualDoor single-command operation alongside a Yale Unity Security Screen Door Lock

Without the hub the lock is fully functional at the door: keypad entry, Bluetooth app control and HomeKit all work. The hub adds distance, not capability at the door. See the Hub 2 specifications, Chapter 08 on what a gateway actually does, and why smart locks drop off Wi-Fi if you run a mesh network.

Security and Privacy Features

  • Wrong code lockout. After five consecutive wrong entries the keypad shuts down for 60 seconds and flashes red.
  • All Code Lockout Mode. The Master Entry Code holder can suspend every user code at once, leaving only the master working. A red padlock shows on the keypad when active.
  • Privacy button. Held for four seconds on the inside lock, it disables all PIN codes - a do-not-disturb mode for the door. Read what an internal snib or privacy mode actually disables before relying on it.
  • Master Entry Code separation. Yale recommends a master code of six or more digits used only for programming, with a separate everyday code for entry.
  • Auto Re-lock. Off by default. Once enabled, the deadbolt re-throws after 30 seconds, 60 seconds, 2 minutes or 3 minutes.
  • Inside notification light. Shows locked status on the inside escutcheon. Disabled by default and switched on in Advanced Lock Settings.
  • One Touch Locking. Enabled by default. A single press of the keypad throws the bolt without a code.

Battery and Power

  • 4 x AA alkaline batteries, supplied in the box.
  • 9V emergency power. Hold a 9V alkaline against the two contacts under the keypad, either way round, then wake the lock and enter your code.
  • Low battery warning. A red battery indicator on the keypad flashes and the lock announces low battery. Replace all four cells together with fresh alkalines.
  • Alkaline only. Yale specifies alkaline cells. Lithium and rechargeable cells report voltage differently and can mask a genuine low-battery condition.
  • Alignment affects battery life. A bolt that binds in the strike draws far more current than one that runs free. See door alignment and what actually fails.

Choosing the right through-bolts
Three screw sets are supplied and only one pair is used. Green set B suits a 35mm door, black set C is the standard for 44.5mm, and silver set D covers 51 to 57mm. Check the door with the supplied door checker before assembly - fitting the wrong length is the most common reason a keypad will not sit flush.

Suitable Uses

  • Residential front, back and internal-garage entry doors under cover
  • Timber, fibreglass and aluminium doors with a standard single-bore deadbolt preparation
  • Doors 35 to 57mm thick at a 60 or 70mm backset
  • Households that want a genuinely key free door and already have a second way in
  • Apple HomeKit households wanting a lock that pairs without extra hardware
  • Holiday houses and long-stay rentals where codes are issued and revoked remotely with the Connect Plus Hub 2
Not suitable for
Gates, exposed or unroofed doorways and any door where the escutcheon takes weather. Not suitable as the only lock on a dwelling with a single entry point, because there is no key override. Not a fire door lock - Yale publishes no AS1905.1 fire test for the Assure range; see the Yale Unity Entrance Fire Rated with DDA Lever instead. Not for doors with a lever or knob cut-out only and no deadbolt bore - use the Yale Assure Keyed Lever there.

Installation Tips

On a door already prepared for a deadbolt this is a Phillips screwdriver job. On a new or unprepared door you will also need a drill, a 54mm hole saw, a wood chisel, a tape and a level. The points below come from Yale's own manuals and from what we see on site. More at Chapter 12 - Installation and Troubleshooting.

  • Keep the bolt retracted. The bolt must be in the retracted, unlocked position through the whole assembly, and again before the batteries go in. Most first-time failures trace back to this.
  • Check the door before you start. Use the supplied door checker to confirm thickness, backset, cross bore, edge bore and strike pocket depth. Set the adjustable deadbolt to 60 or 70mm to match.
  • Route the cable under the bolt. The keypad harness passes beneath the deadbolt and through the cable hole in the mounting plate. Use the cable hooks and do not pinch it - a pinched harness causes scrolling numerals and phantom failures.
  • Seat the cable connector fully. Push until it is firmly home in the adapter on the inside lock. A partly seated connector is the classic cause of fast battery drain.
  • Thumbturn vertical. Check the thumbturn sits vertical and turns freely before the batteries go in.
  • Batteries out before the module. The Home Module or a network module can only be inserted or removed with the batteries out.
  • Let it hand itself. With the bolt retracted, fit the batteries and the lock will hand automatically. If the bolt will not throw afterwards, re-hand it from the settings menu.
  • Manual screwdriver on the strike. Yale specifically warns against power drivers on the strike plate - they strip heads and enlarge holes. If the bolt is tight, bend the strike tab slightly or deepen the strike pocket.
  • Handing and alignment reading. Understanding door handing and the three most common DIY mistakes.

Frequently Asked Questions

Is there a key override if the batteries die?
No. The Assure Lock SL has no keyway at all. If the batteries go flat, hold a 9V alkaline against the two contacts on the underside of the keypad, wake the lock and enter your code. Yale still recommends this model only where the dwelling has another way in. If a physical key matters to you, choose the Yale Assure Lock Keyed instead - identical door prep, C4 cylinder added.
Do I need the Connect Plus Hub 2?
Only for remote access and voice control. Keypad entry, the Yale Home App over Bluetooth and Apple HomeKit at the door all work without it. Add the Connect Plus Hub 2 when you want to lock or unlock from outside Bluetooth range, receive live notifications, or use Alexa, Google Home or SmartThings.
Will it fit my door?
It needs a standard single-bore deadbolt preparation: a 54mm cross bore, a 25mm edge bore and a 60 or 70mm backset, on a door 35 to 57mm thick. If your door has a deadbolt already, it will almost certainly fit. If it only has a lever or knob and no separate deadbolt hole, use the Yale Assure Keyed Lever. See how to measure your backset.
Can I fit it to a gate or an exposed door?
No. Yale publishes no IP rating for this lock and states it is not suitable where the escutcheon is exposed to outdoor elements. Keep it to sheltered entry doors. Salt air is a further concern on the coast - the Yale warranty excludes corrosion damage.
Does it work with an Android phone?
Yes, fully. The Yale Home App is free on Google Play and the App Store and behaves the same on both - entry codes, guest access, the activity trail, Auto-Unlock and DoorSense alerts are all there. The only Apple-specific feature is HomeKit, which pairs at the lock without a gateway. Android households get Google Home, Amazon Alexa and Samsung SmartThings by adding the Connect Plus Hub 2, which is the same box an Apple household needs for remote access.

Additional Information

Handing is automatic, so nothing to specify
Unlike a leverset, there is no left or right hand version and nothing to nominate at order. The lock detects its own orientation on the first battery insert. If it is later moved to a different door, re-hand it from the settings menu. Background: field-reversible handing explained.
Set your master code up properly
Yale's own guidance is to make the Master Entry Code six or more digits, use it only for programming, and create a separate everyday code for entry. The master code also unlocks the door, so treating it as a daily code exposes your programming access to anyone watching the keypad.
Auto Re-lock is off out of the box
Many buyers assume the deadbolt re-locks itself by default. It does not. Enable Auto Re-lock in Advanced Lock Settings and pick 30 seconds, 60 seconds, 2 minutes or 3 minutes. The Yale Home App exposes a separate, longer auto-lock timer - the two are different mechanisms, so set the one you actually want.
Coastal installations and the warranty
The Yale warranty specifically excludes corrosion, including coastal air and salt spray. On beachfront and near-coastal Gold Coast properties, a sheltered doorway and a regular wipe-down make a real difference to how long the finish and the electronics last. See our honest assessment of Yale in coastal Australia and how long digital locks last.
A binding door will eat batteries
The single biggest driver of poor battery life on any motorised deadbolt is a bolt that has to fight the strike. If you feel resistance turning the thumbturn with the door closed, fix the alignment before blaming the lock. What actually fails on electronic locks.

Yale Assure Lock SL - FAQ, Setup and Owner's Guide

Everything owners and installers actually ask about the Assure Lock SL, grouped by topic. For questions that apply to smart locks generally, see Chapter 13 - Smart Lock FAQ and the full Buyer's Guide.

Entry Codes and Access

How long can an entry code be?
At the keypad, 4 to 8 digits. In the Yale Home App, 4, 5 or 6 digits. Yale has documented an iOS quirk where a freshly created 5-digit code can fail on the first attempt; editing the code afterwards clears it. Four and six digit codes work first time.
How many entry codes can the lock hold?
Yale's documents do not agree, and we will not publish a number we cannot stand behind. All sources agree on 25 codes with no network module fitted. The installation instructions quote 250 with a Zigbee or Z-Wave network module and a lower figure again for Bluetooth operation, while the later user manual quotes 250 with the module and 25 without. Since the Australian build ships a Bluetooth Home Module rather than a Zigbee or Z-Wave module, we have asked ASSA ABLOY Australia to confirm which figure applies here. If code capacity is critical to your project, ask us before ordering. Related: how PIN credentials work.
My codes stopped working after I set up the app. Why?
Entry codes created at the keypad before the lock is paired to the Yale Home App are wiped by the pairing process. Re-create them inside the app. This is by design and is the most common support call on the Assure range. Codes made in the app are also the only ones that show up in the activity trail.
Can two people share the same code?
No. The lock rejects a duplicate. Each user needs their own code, which is also what makes the activity trail meaningful.
What is All Code Lockout Mode?
A master-only switch that suspends every user code at once while leaving the Master Entry Code working. A red padlock icon appears on the keypad when a suspended code is tried. Useful when a property is between tenants or when you want to cut access immediately without deleting codes one by one.
Can I give someone temporary access?
Yes, through the Yale Home App. Access can be Always, Recurring on a schedule, or Temporary between two dates. Temporary codes expire on the end date and are removed from the guest list automatically seven days later, which frees code memory on the lock.

App, Smart Home and Voice Assistants

Does it work with an Android phone?
Yes, and with no functional penalty. The Yale Home App is a free download on Google Play and on the App Store, and the two versions are the same: entry code creation and deletion, guest and temporary access, the 24/7 activity trail, Auto-Unlock, Auto-Lock and DoorSense alerts. The one genuinely Apple-only item is Apple HomeKit, which pairs to the Home Module at the lock without any gateway. For Google Home, Amazon Alexa or Samsung SmartThings you add the Connect Plus Hub 2 - and Apple users need that same hub for remote access, so past the doorstep the platforms are level. Some of Yale's marketing leads on HomeKit because that is the hub-free integration; it is not a statement about Android support.
Does it record who came and went?
Yes, once the Yale Home App is set up, on either platform. The 24/7 activity trail logs each entry against the user who made it. One caveat worth knowing: only entry codes created inside the app appear in the trail, so set codes up through the app rather than at the keypad.
Does Apple HomeKit need the hub?
No. HomeKit pairs to the Yale Home Module over Bluetooth at the lock itself. Siri works from an iPhone, iPad or Apple Watch in range. Remote HomeKit control still depends on your own Apple home hub, exactly as it does for any HomeKit accessory. Compare the ecosystems in Chapter 15.
How does Auto-Unlock work?
The app watches your phone leave and return using geofencing, then completes the unlock over Bluetooth as you reach the door. It only arms once you have genuinely left the area, so it will not fire while you are in the back garden. Worth knowing: only one lock per keychain can use Auto-Unlock, so on a two-lock home you pick which door it applies to.
Which voice assistants work?
Amazon Alexa, Google Home and Samsung SmartThings, all of them via the Connect Plus Hub 2 and all of them independent of whether you carry an Android or an Apple phone. Apple Siri is the exception that works through HomeKit without the hub. See Chapter 08 for what a gateway does and does not add.
Can it open my security screen door at the same time?
Yes, with DualDoor. Pair the Assure Lock SL and a Yale Unity Security Screen Door Lock to the same Connect Plus Hub 2 and one command opens both. Read how DualDoor entry actually works first - the screen door needs its own clearance check.
The app keeps losing the lock. What should I check?
Bluetooth range first - the phone needs to be genuinely close. If you run the Connect Plus Hub 2, check it is on the 2.4GHz band and within range of both the router and the lock. Mesh networks that steer clients between bands are a common culprit; see band steering and smart locks.

Power and Batteries

What batteries does it take and are they included?
Four AA alkaline cells, supplied in the box. Yale specifies alkaline. Lithium and rechargeable cells hold a flat voltage curve and then collapse, which defeats the low-battery warning.
What do I do if the lock is dead and I am outside?
Hold a 9V alkaline battery against the two metal contacts on the underside of the keypad. Polarity does not matter. The keypad wakes, you enter your code, and the door unlocks. Replace all four AA cells straight afterwards. It is worth keeping a 9V in the car or with a neighbour, since there is no key.
Why are my batteries flat so quickly?
Three usual causes. A cable connector that is not fully seated in the inside lock, a deadbolt binding in the strike, or a door that has dropped on its hinges. All three make the motor work harder on every cycle. Check the thumbturn with the door closed - it should turn with no resistance. More detail in the realities of electronic door locks.
How is low battery indicated?
A red battery symbol on the lower left of the keypad flashes and the lock announces low battery on entry. Yale does not publish a percentage threshold for this model.

Fit, Door Prep and Installation

What door preparation does it need?
A 54mm cross bore through the door face, a 25mm edge bore for the bolt, and a 60 or 70mm backset. Door thickness 35 to 57mm. A marking template and a door checker are supplied for new doors. See Chapter 02 on door preparation.
Do I need to specify the handing?
No. The lock hands itself electronically the first time the batteries go in, with the bolt retracted. If you move it to another door later, re-hand it from the settings menu with the bolt retracted.
Which through-bolts do I use?
Only one of the three supplied pairs. Green set B for a 35mm door, black set C for the 44.5mm standard, silver set D for 51 to 57mm. Using bolts that are too long stops the keypad seating flush and strains the housing.
Can I fit it to an aluminium door?
Yale lists timber, fibreglass and aluminium. In practice the constraint is the stile - the escutcheon needs enough flat face either side of the 54mm bore. On narrow-stile aluminium, look at the Yale Unity Slim instead, which is purpose-built for narrow frames. Check stile width in Chapter 02.
Is this a DIY job?
On a door already prepared for a deadbolt, yes - a Phillips screwdriver is the only tool listed. On a new or unprepared door you are boring a 54mm hole through the face and chiselling a faceplate mortice, which is where most DIY installs go wrong. We offer installation across the Gold Coast if you would rather it was done once, properly.

Security, Privacy and Compliance

Is a keyless lock less secure?
It removes the attack surface that picking, bumping and cylinder snapping rely on, and it removes the risk of a copied key circulating. What it adds is a dependency on power and on code discipline. The lock is ANSI/BHMA A156.36 Grade 2 certified and carries an Australian Cyber Security Declaration. Read the trade-offs of locks without an override.
What is the Cyber Security Declaration?
Under the Australian Cyber Security Act, IoT consumer products carry a manufacturer declaration of compliance. ASSA ABLOY Australia has issued one for this model (Cyber-AU-00007) covering firmware V4.5.3 with a three year support period from 29 January 2026. The PDF is linked in the PDF Files tab. Background on Australian standards: Chapter 11.
Can someone see my code from the wear on the keys?
The touchscreen is a flat capacitive surface with no moving keys, so there is no mechanical wear pattern. Fingerprint smudging is still worth wiping occasionally, and rotating the everyday code from time to time is sound practice on any keypad lock.
What is the privacy button for?
Held for four seconds on the inside lock, it disables every PIN code so nobody can enter from outside. It is a do-not-disturb function, not a security lockdown, and it can be released from inside at any time. Read the real-world perils of internal snib functions before using it in a rental or share house.
Is it fire rated or DDA compliant?
No. Yale publishes no AS1905.1 fire test and no AS1428.1 accessibility claim for the Assure range, and no AS4145.2 security grade either. For a fire door, use the Yale Unity Entrance Fire Rated with DDA Lever. Chapter references: AS1905.1 and AS4145.2.

Troubleshooting

The keypad will not respond.
Press the Yale logo to wake it - the numerals only light after that. If nothing happens, check battery polarity and condition, then check the keypad harness is fully seated and not pinched. If the door is locked and you are outside, use the 9V back-up.
The lock chimes but the bolt will not throw.
Almost always handing or alignment. Re-hand the lock from the settings menu with the bolt retracted. If it still binds, check for debris in the door gap, then adjust the strike - bend the tab towards the strike face, or deepen the bolt pocket in the jamb.
An X appears on the keypad after a valid code.
The bolt failed to fully retract. That is a mechanical symptom, not a code problem. Work through the strike alignment and door swing before anything else.
The numerals scroll or flicker.
The keypad harness is not lying flat behind the inside escutcheon. Remove the inside lock, route the harness along the side of the escutcheon, tuck it under the plastic cable guide and reassemble.
How do I factory reset it?
Remove the battery cover and batteries, take off the inside lock to reach the reset button beside the cable adapter, hold that button for at least three seconds while refitting the batteries, then release. Every code including the master is erased and a new Master Entry Code must be created before anything else.
It says wrong number of digits.
The code entered was too short, too long or incomplete. Re-enter it followed by the check key. Remember the check and gear symbols cannot form part of a code, and a code must be entered within about five seconds of waking the keypad.

Suitability and Alternatives

I want the same lock but with a key.
That is the Yale Assure Lock Keyed - the same body, same door prep, same Home Module, with a C4 keyway added. It is the direct upgrade path if a key override matters.
My door has no deadbolt hole, only a lever.
Use the Yale Assure Keyed Lever, which is the same platform in a cylindrical deadlatch leverset that suits a single-bore lever preparation.
I want fingerprint entry.
The Assure range has none. Look at the Yale ByYou Pro, Yale Kyra Pro or Yale Luna Pro+ - all mortice-format push-pull locks rather than deadbolts, so the door preparation differs entirely.
I do not want an app at all.
The Yale Libi Digital Lock Keyed is a deliberately offline keypad deadbolt - no app, no Bluetooth, no gateway, and a mechanical key override. Same range of Australian door preparations.
How does it compare to other keypad deadbolts?
Against the Carbine CDL2 digital deadbolt and the McGrath X3, the Assure SL trades a key override away in exchange for the Yale Home and HomeKit ecosystem. Against the Igloohome Smart Deadbolt Go, Igloohome wins for offline code generation on short-stay rentals while Yale wins on smart home integration. The Lockwood 001Touch Plus is the closest Australian-brand alternative on a deadlatch rather than a deadbolt.
Where should I keep a spare key if there is no keyway?
There is no key to keep - which is the point, but it also means a flat battery and no 9V is a genuine lockout. Many owners keep a spare set of house keys for a second door in a key safe or Bluetooth key box. See secure key storage options.

About the parts diagram
The artwork above is Yale's original parts diagram and labels the module as an optional item. That reflects the international NR build. The Australian HK part number supplied here includes the Yale Home Module and DoorSense in the carton.
Not included
A 9V battery for emergency power is not supplied. It is worth buying one at the same time and keeping it somewhere accessible but not inside the locked house, because this lock has no key override.

All dimensions in millimetres. Outside keypad 66 x 91.5 with a 17.4 projection from the door face. Inside lock 70 x 158 with a 53.9 projection. Note that ASSA ABLOY Australia's specification sheet quotes the inside lock as 175 high x 75 wide, and the Yale catalogue quotes 168 x 70; the drawing is reproduced here exactly as issued and should be used for clearance checks.
Clearance check before ordering
Measure the flat face of the door stile either side of the bore. The outside keypad needs 66mm of clear width and the inside lock 70mm, plus room for the thumbturn to rotate. On narrow-stile aluminium doors, check this before committing.
