Fingerprint Door Locks
Fingerprint door locks turn your finger into the key. Press, step in, done — no app, no code, no key to lose. KeldCo fingerprint locks are built for Australian doors, backed by a 12-month warranty, and ship from Australia.
A fingerprint, read locally, in under a second
A fingerprint door lock uses a capacitive sensor to read the unique ridges of your finger. The pattern is stored locally on the lock — not in the cloud — and when it matches, the motor retracts the latch. No subscription to unlock your own door, and no privacy headache if your Wi-Fi provider goes down.
Buying guideWhat to look for in a fingerprint door lock
- Enrolment capacity. Four prints is the bare minimum. Fifty gives you room for tradies, cleaners and guests without rotating slots.
- Backup access. Fingerprints fail — wet hands, cuts, kids. Look for PIN or key fallback. Ours offer five ways in.
- Auto-lock. Locks itself after a set delay. Catches the moment everyone forgets.
- Battery life. 4 x AA lasts about 6 months with normal use. Rechargeable means more frequent top-ups.
- Australian door fit. Standard AU doors are 35–44.5mm thick with a 60mm or 70mm backset. Imported locks often don't fit.
- Security certification. IP65 for weather. Cyber-security certification if the lock is Wi-Fi connected.
Fingerprint vs PIN vs card vs key
| Method | Best for | Weakness |
|---|---|---|
| Fingerprint | Daily household use | Wet or injured fingers |
| PIN code | Guests, temporary access | Someone can watch you type |
| IC card | Kids, elderly, those without phones | Can be lost or stolen |
| Real key | Emergency backup only | The thing you bought a smart lock to avoid |
Fingerprint door lock questions
Are fingerprint door locks secure?
Yes. Fingerprint patterns are stored locally on the lock, not sent to the cloud, and the capacitive sensor requires a live finger — printed images won't work. Look for cyber-security certification if the lock is Wi-Fi connected.
Do fingerprint door locks need Wi-Fi?
No. The fingerprint reader works offline. Wi-Fi is only needed for remote access via an app — unlocking from work, or granting someone a temporary code.
Can I still use a physical key?
Yes. KeldCo fingerprint locks include a real key for emergency entry. If batteries die or electronics fail, you're never locked out.
How many fingerprints can a smart lock store?
Varies by model. Entry-level locks hold 10 to 20. Premium locks like Door Nerve store up to 50 — enough for every family member, tradies, cleaners and regular visitors.
Do fingerprint door locks work in cold weather?
Yes. Capacitive sensors read ridges even with cool fingers. IP65-rated locks like ours handle Australian conditions year-round.
How long do the batteries last?
About 6 months with normal use on 4 AA batteries. The app warns you when batteries get low. If they die, you can still use the physical key.
Will a fingerprint lock fit my Australian front door?
KeldCo fingerprint locks fit standard Australian doors 35–44.5mm thick, with a 60mm or 70mm backset. Install takes about 10 minutes with the included template.
