Vault Guardian Lever Smart Lock with 3D Face Recognition
At A Glance
Not Available
The Vault Guardian (Vault_Guardian) is a lever-handle smart lock that combines 3D facial recognition with multiple credential options for residential entry doors. It stores up to 50 face profiles, 200 fingerprints, 150 PIN codes and 200 RFID cards, and a mechanical key override is included.
The Guardian supports facial recognition, fingerprint, PIN code, Bluetooth app, RFID card and mechanical key access, with optional remote access and voice control available through the Vault G5 Wi-Fi Gateway.
Its lever format suits mortice lever door preparations where a more traditional handle style is preferred over push-pull hardware, while still providing a feature-rich biometric entry system.
Usually ships in 3 business days.
Key Features
- Lever-handle smart lock with 3D facial recognition - up to 50 face profiles.
- Supports fingerprint (200), PIN code (150), RFID card (200), Bluetooth and app control.
- Optional remote access and smart-home integration via the Vault G5 Wi-Fi Gateway - dual-band, avoids the band-steering problem common on single-band gateways.
- Electronic Locking Button privacy function - lock the door from inside so only the app or the mechanical key opens it.
- Powered by an 18650 rechargeable lithium battery with USB-C charging; mechanical key backup included (2 keys).
- Lever format suits mortice lever door preparations where push-pull hardware is not preferred.
- IP66-rated external module for everyday outdoor exposure; suits doors 35mm to 60mm thick.
Facial Recognition Access
The Vault Guardian supports 3D facial recognition for touch-free entry. The 3D sensor type differs meaningfully from 2D camera-based recognition in spoofing resistance - see our buyer's guide for the technical distinction.
Facial recognition works alongside fingerprint, PIN, RFID card, Bluetooth app control and backup key access. Face capacity for the Guardian is 50 face profiles, stated in the Guardian's own manual.
If installing in a commercial, strata, or managed rental context, review the Australian Privacy Act obligations that apply to facial recognition data collection before proceeding.
The external (outside) module is IP66 weather rated for everyday outdoor exposure. The internal module is for interior use only and is not weather rated.
What's in the Box
This lock is supplied with a 6085 (60mm backset) mortice for hinged/swinging doors as standard.



Battery, Power & Backup Access
- Powered by an 18650 rechargeable lithium battery; a USB-C charging cable is not included. For realistic expectations on charge cycles and maintenance, see our guide to smart lock battery life.
- A low voltage alarm warns when the battery drops below 7.2V, so recharge promptly once it sounds.
- Mechanical key backup remains available for emergency entry in all power conditions.
- Confirm battery charge and key access during initial setup.
The Guardian's electronic locking button lets you secure the door from the inside. The function is enabled in the Vault Smart Locks app; when the button shows its red (locked) state, the door can only be opened by the app or the mechanical key - keypad, card, fingerprint and face entry are blocked until it is released.

Wi-Fi Remote Access (Optional)
This smart lock operates via Bluetooth connectivity as standard, from the Vault Smart Locks app on iOS
and Android
. Remote access and internet-based control are available only when paired with a compatible Vault Wi-Fi gateway.
When connected to a gateway, you can remotely manage access, view activity, and add Alexa or Google Home functionality on supported systems. The G5's dual-band Wi-Fi avoids the band-steering problem that affects single-band gateways on modern routers.
For a full comparison of gateway generations, see our G2 vs G3 vs G4 vs G5 gateway guide.
For remote functionality, see the Vault G5 Gateway.
This lock includes a mechanical key override to ensure access remains available if battery power is unavailable or electronic access cannot be used.
Frequently Asked Questions
Yes. The Guardian uses 3D facial recognition with a capacity of 50 face profiles, stated in the Guardian's own manual. The 3D sensor type differs from 2D camera-based recognition in spoofing resistance.
Yes, but only when paired with the Vault G5 Wi-Fi Gateway. Without the gateway, the lock operates locally via Bluetooth, keypad, face recognition, fingerprint, RFID and mechanical key. Our guide to what a gateway does explains the difference between local and remote-enabled operation.
Yes. The Vault Guardian Vision adds a two-way video intercom, a built-in indoor display screen and built-in 2.4GHz Wi-Fi (no separate gateway needed), in the same lever format.
No. Vault smart locks are not certified for fire-rated doors. For Queensland fire door compliance requirements, see Chapter 05 of our Buyer's Guide, or browse fire-door-suitable smart locks.
Yes. Checking your door type, existing door preparation and mortice backset before purchasing is strongly recommended - the Guardian suits doors 35mm to 60mm thick with a 72mm clearance. See our installation guide for when professional assessment is advisable, and our guide to common hardware selection mistakes.
Additional Information
This page previously stated an IP55 rating. The Guardian manual's own specification badge states IP66, and that figure was adopted on 2026-09-26. As with any two-part smart lock, the rating applies to the external (outside) module only; the internal module is for interior use. Correct installation and maintenance still matter, particularly in coastal Queensland environments where salt air accelerates wear.
The Vault Guardian Vision is the video-intercom variant of this lock, adding a camera, indoor screen and built-in Wi-Fi. Other levers in the range include the Vault Prime, the Vault Triton and the Vault Pearl. For the full lineup, see the Vault smart lock range overview.
Deploying facial recognition in a commercial, strata, or managed rental setting may trigger obligations under the Australian Privacy Act. Review these requirements before installation. The manual's colour row lists black or silver hardware; the product we stock on this listing is Black.
A mortice is included in the box, but the correct type for your door still needs to be confirmed and selected at checkout. Hinged and sliding doors require different mortice types - the hinged swinging mortice and the sliding hook mortice are the two common options. Choosing the wrong mortice is one of the most common installation errors - see our guide to common hardware and backset selection mistakes. On the Gold Coast we also offer a measure and install service.
The Guardian is positioned as a residential entry smart lock. It is not suitable for fire-rated doors, storerooms requiring high-cycle durability, or other applications outside its residential design intent. For remote unlocking, notifications and voice control, add the Vault G5 Gateway - see Chapter 08 - Gateway Comparison.
Warranty
Vault Smart Locks products purchased in Australia are covered against defects in materials and workmanship under normal residential or commercial use for:
- Standard range: 12 months from the date of purchase
- Select Signature Range models: 24 months (as stated on the product listing or packaging)

Vault Guardian - FAQ, Setup and Owner's Guide
Deeper answers for owners and buyers of the Vault Guardian. For category-wide questions, see our Smart Lock FAQ (Chapter 13) and the Buyer's Guide.
Access and Credentials
A 3D sensor maps the depth of a face rather than matching a flat image, which makes it far harder to spoof with a photo or a screen. The distinction, and what it means for everyday reliability, is covered in Chapter 06 - 2D vs 3D face recognition.
Face profiles are added from the Vault Smart Locks app: open the lock's user settings, choose Add Face, and follow the on-screen prompts while the person stands in front of the lock's sensor. The Guardian stores up to 50 face profiles, and each can be assigned to a named user so unlock records show who came in.
Yes. Through the Vault app you can issue passcodes that are permanent, timed or one-time, and delete them when they are no longer needed. The Guardian holds up to 150 passcodes alongside its 200 fingerprints and 200 cards, which comfortably covers a family home or a managed short-stay property. See PIN codes explained.
The Guardian ships with three RFID cards and stores up to 200. Additional cards are enrolled at the lock through the app's Add Card flow. See RFID credentials explained, or browse our RFID cards, fobs and tags.
Like most smart locks, the Guardian's mechanical key cylinder is deliberately unobtrusive. Our blog on where the keyhole is hidden shows the usual locations, and how to store the override key covers what to do with the two included keys.
Fit, Mortice and Installation
Timber and aluminium hinged doors 35mm to 60mm thick, with at least 72mm of clear stile for the escutcheon. It ships with a 6085 (60mm backset) hinged-door mortice as standard; sliding doors take the Vault Sliding Hook Mortice selected at checkout. Measure your backset and door thickness before ordering.
Hinged and swinging doors use the standard 6085 mortice or another size from the Vault hinged swinging mortice range; sliding doors need the hook bolt mortice; internal doors that do not need a deadlocking bolt can take the optional 60mm tubular latch. Our guide to backset and mortice selection walks through the decision.
Rebated (overlapping) door pairs need the Vault Rebate Kit to convert the mortice preparation. Confirm latch and strike alignment for your door pair before ordering.
No. The Guardian's handle direction is changed during installation (a three-step procedure in the manual), so one unit suits left and right-opening doors. Set it before the panels go on the door.
A competent DIYer with an existing mortice lever preparation can, following the manual's six-step sequence and the supplied template. If the door needs a new mortice pocket cut, or you are unsure about backset and alignment, professional fitting is the safer path - see when DIY makes sense and our Gold Coast measure and install service.
Power and Batteries
An 18650 rechargeable lithium battery, charged over USB-C (a charging cable is not included in the box). A low voltage alarm sounds when the battery drops below 7.2V - recharge promptly once you hear it. For a realistic view of recharge habits, see the realities of smart lock battery life.
Use one of the two included mechanical keys to open the door, then recharge the battery. Keep a spare key somewhere other than inside the house the lock secures - our blog covers what to do when the battery dies.
Remote Access, App and Smart Home
Only for remote features. Locally, Bluetooth covers pairing, unlocking, user management and record reading when you are at the door. The Vault G5 Gateway bridges the lock to your home Wi-Fi for remote unlock, remote passcode changes and unlock history from anywhere. Chapter 08 explains what a gateway does, and the blog asks whether you need one at all.
The G5 is dual-band, which sidesteps the band-steering problem that stops many single-band gateways pairing on modern mesh routers. The full comparison is in Chapter 08 - band steering and the G2 vs G3 vs G4 vs G5 blog.
Yes, on supported systems - once the lock is paired with the G5 Gateway. Voice control is not available from the lock on its own, because the lock itself has no Wi-Fi radio.
Yes. The Vault app reads the lock's unlock records over Bluetooth when you are at home; with the G5 Gateway added, records can be read remotely as they happen. Each face, fingerprint, code and card can be tied to a named user.
Security and Privacy
Enable the function in the Vault app, then use the button to secure the door from the inside. In its red (locked) state the door only opens by app or mechanical key - outside credentials are refused until the privacy lock is released. It is the smart-lock equivalent of a privacy snib.
In a private home, no special obligations apply. In commercial, strata or managed rental contexts, collecting biometric data can trigger Australian Privacy Act obligations - review Chapter 06's Privacy Act section before rollout.
No. Vault smart locks carry no fire-door certification, so fitting one to a fire-rated door would void the door's compliance. Chapter 05 explains where fire doors are required in Queensland and which locks are certified for them.
Care, Warranty and Support
The Guardian carries Vault's standard 12-month warranty (select Signature Range models carry 24 months, as stated on the listing or packaging). Note that Vault charges a refundable assessment holding fee for warranty assessments - $200 in metropolitan areas and $250 elsewhere - refunded when the claim is accepted. Full terms are in the Vault warranty policy and our Returns & Warranty page.
The IP66 external module handles everyday rain and dust, but salt air is a corrosion question, not a water-ingress one - warranty cover excludes coastal corrosion. Rinse-free wipe-downs and a sheltered mounting position go a long way; see coastal environment realities.

Vault Warranty
Vault Smart Locks products are backed by a manufacturer's warranty against defects in materials and workmanship under normal residential or commercial use. All claims are handled locally by Terry's Tradies Pty Ltd and its associated websites, trading names, and subsidiaries - start with us and we'll manage the process with Vault on your behalf.
Warranty Summary
How to Make a Claim

- Have your product model and serial number (if applicable) ready, along with a brief description of the fault and your installation address.
- We assess your claim with Vault and advise the outcome and next steps. You may be asked to return the product for inspection.
What This Warranty Does Not Cover
- Normal wear and tear.
- Cosmetic damage that does not affect performance.
- Damage caused by incorrect installation, misuse, neglect, modification, or accident.
- Damage due to improper handling, or installation by an unlicensed technician.
- Products that have been disassembled, tampered with, or where the security seal or warranty label has been removed.

Important Notes
Where a Vault product carries an Ingress Protection (IP) rating, that rating is stated on the individual product listing, packaging or technical documentation. Unless stated otherwise in writing, the IP rating applies only to the external-facing side of the lock - not to the internal assembly, handle, battery compartment, electronics, cables or connectors. The internal side must be installed in a dry, sheltered position. An IP rating describes water resistance, not waterproofing: the lock must not be submerged, pressure washed, or exposed beyond its stated rating, and all seals, gaskets and covers must be correctly fitted and undamaged.
Vault's manufacturer policy applies a warranty assessment holding fee, which is refundable if the fault is found to be covered under warranty. If a product is assessed as outside warranty or damaged by an excluded cause, a discounted replacement may be offered. We will confirm any applicable fees and options with you before any assessment proceeds.
This warranty is provided in addition to your rights under the Australian Consumer Law (ACL). Our goods come with guarantees that cannot be excluded under the ACL. You are entitled to a replacement or refund for a major failure, and to have goods repaired or replaced if they fail to be of acceptable quality and the failure does not amount to a major failure.
