ABUS Touch 57/50 Fingerprint Padlock - Weather Resistant

ABUS Touch 57/50 Fingerprint Padlock - Weather Resistant

The ABUS Touch 57/50 opens on a fingerprint. There is no key, no PIN and no app - an enrolled finger goes on the sensor and the shackle releases in under a fifth of a second. What makes it useful to a household or a work crew, rather than to one person, is the way it handles more than one user: the lock stores up to 20 fingerprints, and the first two you enrol become administrators.

Administrators are the only fingers that can add a new print or wipe the lock back to empty. Everyone enrolled after them is a user - they can open the padlock and nothing else. That one distinction is what turns a biometric padlock into something you can genuinely share. A shed four people use. A gym locker two of the family open. A site box where the foreman decides who gets in. A storage cage at a club where members come and go but nobody can re-programme the lock.

Enrolment happens on the padlock itself, with no tools and nothing to pair. Hold a finger on the sensor for about three seconds and release, then present that same finger at least ten more times in slightly different positions - flat, on the tip, rolled left, rolled right - until the LED confirms it. Deleting every stored print is an administrator-only job: hold an administrator finger for six to ten seconds and confirm with the same finger.

Power is a single CR2 3 V lithium cell. There is no mechanical key override on this padlock, so ABUS has made the flat-battery behaviour fail safe rather than fail shut: as the cell runs down the lock sounds an S.O.S. pattern after each opening, and after a few of those warnings it stops closing altogether rather than lock you out of something you would have no way back into.

Where this padlock should live - read this before you buy
ABUS is blunt about it. The lock can be used outside, but they recommend indoors or somewhere sheltered from direct weather. Extended periods of heavy rain, and salt water in particular, can damage the electronics, spoil the way it works and stop the lock opening at all. Their own advice is to treat it the way you treat your phone. There is no IP rating on this product and no ingress classification of any kind - "Weather Resistant" in the name is a catalogue descriptor, not a tested figure, and we are not going to pretend otherwise. If the padlock has to live fully exposed on a gate, a pool fence or anything within reach of the sea air, buy something built and rated for it instead - the Master Lock 4401LHEC Enterprise Outdoor Bluetooth Padlock, or the ASSA ABLOY Aperio P100B-100, which carries an IP66 rating. It is worth reading what an IP rating actually covers and what Queensland conditions do to hardware before you decide.

Key Features

• Fingerprint only. No key cylinder, no PIN pad, no Bluetooth and no app - the sensor is the whole interface. See the rest of our fingerprint locks, or read how biometrics compare with the other credential types in Chapter 3 of the Buyer's Guide and in the blog's rundown of the four technology types in our padlock range.
• Up to 20 fingerprints. Enough for a family, a work crew or a club committee without anybody carrying a key.
• The first two fingers enrolled are administrators. Everyone after them is a user. Only an administrator finger can add another print or delete the lot - which is what makes shared use manageable rather than chaotic.
• Enrolment on the lock, no tools. About a three-second hold, then at least ten reads of the same finger in different positions. The LED tells you when the finger is fully stored.
• Fast, accurate reading. A 508 DPI sensor, recognition in under 200 milliseconds, a false rejection rate of around 5 % and a false acceptance rate below 0.002 %.
• One CR2 3 V lithium cell. Externally replaceable, and your stored fingerprints survive the change - there is no re-programming afterwards.
• Fails safe, not shut. On a low battery the lock sounds an S.O.S. pattern after opening, then after a few warnings refuses to close at all, so it cannot strand your property behind a dead lock.
• Rated to work from -10 °C to +50 °C. Comfortably inside anything south-east Queensland will throw at it, weather exposure aside.

Administrators, Users and Enrolling a Fingerprint

Out of the box - and again after a reset - the padlock opens on any touch of the sensor. It stays that way until the first finger is enrolled, so the first thing to do is claim it. The first two fingers you store become the administrators; everything after that is an ordinary user.

There is no way to delete one user without deleting all of them - removing somebody's access means clearing the lock and re-enrolling everyone who should still have it.

Storing the first fingerprint (this finger becomes administrator 1)

1. Place the finger on the sensor and hold it there for roughly three seconds, then release. The lock answers with a three-tone then single-tone sequence.
2. Present the same finger at least ten more times, moving it each time - flat, on the tip, rolled to the right, rolled to the left. The point is to give the sensor the whole fingertip, not the same patch ten times over.
3. Watch the LED. Blue means the read was stored, red means it was not. Green means that finger now has all ten prints recorded and is finished. If you do not get green, keep presenting the finger.

Adding another fingerprint (administrator only)

1. Place an administrator finger on the sensor for about three seconds and release, and wait for the three-tone then single-tone sequence.
2. Present the new finger at least ten times, displaced each time, exactly as above.
3. Confirm with the administrator finger.

Deleting every stored fingerprint (administrator only)

1. Hold an administrator finger on the sensor for six to ten seconds - noticeably longer than a normal enrolment hold - and wait for the three-tone then single-tone sequence, then release.
2. Confirm with the administrator finger and allow the lock a short moment to process.
3. A single confirming tone means every stored print is gone and the padlock is back to opening on any touch.

Getting the best out of the sensor
Enrol at least two fingers, and if you are the only user, enrol every finger you have - there is no key to fall back on. Write down which fingers are stored and keep the note somewhere sensible; six months later nobody remembers. Keep the sensor clean, dry and free of grease, and the finger too. Cuts, abrasions, very dry skin, moisture and hand cream all change a fingertip enough to slow recognition down, and you may need two or three attempts. One thing worth knowing before you need it: while the battery is low you can still open the lock, but you cannot save or delete fingerprints. Change the cell first, then make your changes. There is more on enrolment technique and wet-finger failure modes in Chapter 3, Fingerprint and Biometric access.

Do not use this lock where somebody may need in under pressure
This is ABUS's own restriction and it is worth repeating in plain language. Do not fit this padlock to anything that has to be opened in a hurry or under stress - medicine or defibrillator cabinets, emergency doors, chains across an escape route, firearm storage. Panic makes fingers sweat, and a sweaty finger may not read. A product that opens 999 times out of a thousand is fine on a shed and completely wrong on a cabinet somebody has to open while their hands are shaking.

What's in the Box

• ABUS Touch 57/50 fingerprint padlock
• Multilingual user booklet covering battery fitting, enrolment, deletion, technical data, conformity and warranty

Whether a CR2 cell ships in the box is not something we can confirm from the paperwork - check your packaging. Either way it is worth having a spare: CR2 is a common camera cell and every hardware shop and camera counter carries it. ABUS asks for a quality brand-name cell, naming Varta and Panasonic as examples.

Suitable Uses

• Sheds, garages and home workshops shared by several people, under cover. Compare the rest of the range on our smart padlocks page.
• Gym, school, club and staff lockers, where issuing and recovering keys is the real cost.
• Tool chests, site boxes and plant cages under a roof, with the supervisor holding an administrator finger and the crew enrolled as users.
• Storage cages, garage cupboards and internal roller-door latches in units and apartment blocks.
• Caravan, boat and trailer lockers that live under cover between trips - not ones permanently exposed to spray.
• Households that keep losing, copying or lending keys. Everybody carries a finger; nobody carries a key.
• Any situation where you want to hand access to someone and take it away again without changing a lock - though note that revoking one person means clearing the lock and re-enrolling the rest.

Not the right lock for: anything permanently exposed to heavy rain or salt air; anything that must be opened under stress or in an emergency; and anything where you need a guaranteed way in if the battery goes flat and nobody noticed the warnings. If you are weighing the formats up, the blog walks through which smart padlock suits which job, and what actually makes a padlock "smart" is a good place to start if this is your first one.

ABUS Electronic Padlocks - Item Code Family

This product (bold row) is the fingerprint model. The two EVEROX One models are the app-driven side of the same shelf - same idea, different credential. None of the three has a mechanical key override. We have written all three up against the rest of the market in our smart padlock guide, where the ABUS Touch 57/50 has its own section.

Full Specifications

There is no IP rating row on this table because there is no IP rating on this product. Shackle diameter and shackle clearance are not stated in the documentation we hold either - if those measurements decide whether this padlock fits your hasp, ring us before you order and we will measure one. More on what the ratings mean is in Chapter 11, IP Ratings and Ingress Protection, and on corrosion in the same chapter's corrosion-resistance section.

Dimensions

ABUS padlock measurement guide - it shows where each padlock measurement is taken (body width, shackle diameter, and the horizontal and vertical clearance inside the shackle), which is what you need when you are checking a hasp. The Touch 57/50 is a 50 mm body. Shackle diameter and clearance figures are not published in the documentation we hold for this model, so we are not going to guess at them - ring us with your hasp opening and we will measure a lock and tell you whether it goes on.

Battery & Power

• One CR2 3 V lithium cell, 850 mAh. ABUS asks for a quality brand-name battery and names Varta and Panasonic as the sort of thing they mean.
• ABUS does not quote a service life in months or in openings, so we are not going to invent one. What we can tell you is how it warns you, which matters more.
• Low battery: after you open the lock it sounds an S.O.S. - three short tones, three long, three short. That is the signal to change the cell.
• After a few of those warnings the padlock will not close. This is deliberate and it is the right design on a lock with no key override: it would rather stay open than shut on a dying battery and leave you with no way in.
• Changing the cell does not wipe anything. Your fingerprints stay stored and there is no re-programming to do afterwards.
• While the battery is low you can still open the lock, but you cannot save a new fingerprint or delete the stored ones. Change the cell first.
• The battery is a lithium cell: keep it away from children, watch the polarity, do not short the terminals, and do not pierce, heat or dismantle it. Replace a flat cell promptly rather than leaving it in the lock.

The flat-battery question, answered honestly
Every electronic padlock buyer asks it and most product pages dodge it. Here is the straight answer: there is no key, no PIN and no external power point on this lock, so if you ignore every S.O.S. warning and the cell dies completely while the shackle is closed, you are looking at a cut-off. What stops that happening in practice is the refusal to close - the lock takes itself out of service before it can trap anything. Keep a spare CR2 in the drawer and change it the first time you hear the S.O.S. There is broader reading on this in what to do when the battery dies, in battery life, the truth rather than the marketing version, and in Chapter 13's power and battery section. Chapter 1 also covers how electronic locks are powered in general.

Frequently Asked Questions

How many fingerprints does it hold, and who is allowed to add one?
Up to 20 fingers. The first two you enrol are administrators and everybody after them is a user. Only an administrator finger can add a new print or delete the stored ones - a user can open the lock and nothing more. If you are the only person using it, ABUS suggests enrolling every finger you have, because there is no other way in. The full step-by-step is further up the page under Administrators, Users and Enrolling a Fingerprint.

Is there a key override or a backup PIN?
No, neither. There is no key cylinder in the body and no keypad - the fingerprint sensor is the only way this padlock opens. That is a deliberate design choice and it cuts both ways: nothing to pick, nothing to bump, no key to copy or lose, but also no fallback. Read the "no key override" issue for Gold Coast buyers and smart locks that don't have a key override before you commit - they are honest about the trade-off.

What happens when the battery runs down?
The lock tells you, then it protects you. After each opening on a low cell it sounds an S.O.S. - three short tones, three long, three short. Ignore that for long enough and it stops closing altogether, which means it cannot lock shut on a dying battery. Change the CR2 cell when you first hear the warning; your fingerprints stay stored through the change and nothing needs re-programming. One catch worth knowing: while the battery is low you cannot enrol or delete fingerprints, only open. More on flat-battery planning in what to do when the battery dies and in Chapter 13.

Can I leave it outside on a gate?
We would rather you did not, and so would ABUS. Their guidance is to use it indoors or somewhere it is not directly exposed to weather; long spells of heavy rain, and salt water especially, damage the electronics and can stop the lock opening. It carries no IP rating. A carport, a shed, a covered storage cage, a locker room - fine. A beachfront gate or an unsheltered pool fence - buy a padlock built for it, such as the Master Lock 4401LHEC Enterprise Outdoor Bluetooth Padlock. Our own coastal experience is written up in coastal environments, Gold Coast specific and why coastal Queensland is not gentle on hardware.

Will it read my finger if it is wet, dirty or cut?
Sometimes, and less reliably. The sensor is a precision component and both it and the fingertip need to be clean, dry and free of grease. Moisture, dust, hand cream, very dry skin, a fresh cut or an abrasion all change the print enough that you may need two or three goes. That is what the roughly 5 % false rejection rate looks like in real life - not a failure, just a re-present. The practical answer is to enrol more than one finger per person, and to enrol fingers from both hands if you work with your hands. Chapter 3 on fingerprint access goes through the failure modes properly, and the five questions to answer before you buy is a good sanity check.

Additional Information

Enrol more than one finger - this is the single best habit
ABUS recommends at least two, and every finger if you are the sole user. It costs you five minutes once and it covers the day you turn up with a bandage, a blister or a hand full of grease. Remember the first two fingers you store are the administrators, so think about whose fingers those should be before you start rather than after. Write down what is enrolled and where the note lives.

Never on anything that must open under pressure
Medicine cabinets, defibrillator cabinets, emergency doors, chains across an escape route, firearm storage. ABUS names these specifically and the reason is simple: panic makes fingers sweat and a sweaty finger may not read. This is the one hard prohibition on the product, and it is not a legal disclaimer - it is a real failure mode at exactly the wrong moment.

"Weather resistant" is a description, not a rating
Worth saying twice because the name invites the wrong assumption. There is no IP figure on this padlock and no ingress classification, and the only environmental instruction that comes with it is a restriction, not a permission: keep it out of direct weather, avoid prolonged sunlight, and keep it well away from salt water. Sheltered outdoor mounting is reasonable; full exposure is not. If you want to understand what a real rating would look like, Chapter 11's IP ratings section explains the scale, the corrosion-resistance grade covers salt air, and the Queensland-specific section is the one to read if the lock is going anywhere near the water.

Would you rather use a phone than a finger?
Then look at the ABUS EVEROX One 61/50, which is the same idea on the same 50 mm body class but opens from the ABUS One app over Bluetooth, or the EVEROX One 61/45 if you need the narrower body. Outside ABUS, the Igloohome Smart Bluetooth Padlock 2 adds offline PIN codes, which is the one thing a fingerprint cannot do - you cannot send somebody a fingerprint over the phone. A fingerprint wins when the people are in front of you; a code wins when they are not.

Before you sell it, lend it or throw it out - clear it
Your fingerprints live on the lock, not in a cloud, which is the good news. It also means the responsibility for clearing them is yours: hold an administrator finger for six to ten seconds, confirm, and the padlock goes back to opening on any touch. Do that before the lock leaves your hands. At end of life the cell comes out and goes to battery recycling separately from the lock body. ABUS sits in the commercial and access-control end of the market - there is a short profile of them in Chapter 10's commercial and institutional specialists if you have not bought the brand before.

Warranty

Warranty
ABUS products are backed by a manufacturer's warranty covering defects in materials and workmanship. Warranty periods vary by product - contact us or refer to your product packaging for the period that applies to your model. All warranties are supported under the Australian Consumer Law. Proof of purchase required for all claims. Returns & Warranty | ABUS warranty & returns information

The warranty covers material and manufacturing defects only, with repair or replacement at ABUS's discretion. It does not cover damage from outside influences, improper use, normal wear, or from not following the instructions - which is another reason the sheltered-use guidance above is worth taking seriously. A claim needs the product, the original dated receipt and a short written description of the fault.
