What should I do if I forget my digital lock password?

Forgot digital lock password: first checks

Before you reset anything, try the other ways your lock already knows you. Many digital locks accept more than one credential. Yale, for example, lists fingerprint, PIN or radio-frequency identification (RFID) card access on its YDM7116A mortise lock, with optional app access through a separately sold module and a mechanical key for emergencies.

So check the quick wins. Does your finger still open the door? Is a spare card in a drawer? Can the app open it from your phone? Is the mechanical key in your bag, the car or with a relative?

Then ask the household. If each person in your HDB flat or condo has their own code, a spouse or flatmate may still get you in, and tenants can ask the landlord for the manual. Weighing up lock types for next time? See our digital lock vs mechanical lock comparison.

What a factory reset does

A digital lock factory reset takes the lock back to its out-of-the-box state. Every saved code, registered card and enrolled fingerprint is erased, not only the password you forgot, so everyone in the home must be set up again.

The reset is done from the inside unit, the part of the lock on the indoor face of the door. That keeps it out of reach of anyone in the corridor, but it also means a reset only helps once you are already inside, with the door open and nobody able to remember the code.

The sequence itself varies between brands and can differ between models from the same brand. Your manual or the brand's customer support will give the right one. Steps from a video about a different lock may not match yours, so confirm the model name before you press anything.

How to reset a digital door lock safely

Before you reset digital door lock codes, pick a time when everyone who needs to re-enrol a fingerprint is at home.

1. Confirm you are inside. Work from the indoor side with the door open.
2. Find the manual or brand support. Note the model name on the lock and keep the brand's support line handy.
3. Follow your model's steps. Use only the sequence given for that exact model.
4. Set a new code. Choose something a visitor could not guess, and note it somewhere safe.
5. Re-register cards and fingers. Enrol each person and each card again, one at a time.
6. Test with the door open. Lock and unlock several times from outside before you close the door.

If the keypad will not light up at all, the problem may be power rather than the code, and a reset will not fix it. See our digital lock battery dead guide instead.

Locked outside with no code

Standing in the corridor with no code, card, finger match or key means a reset is not open to you. Call the brand's authorised service first; look up the number on its website or in your purchase emails. A locksmith is the other route.

Expect either to ask for proof that you live there, such as an NRIC showing your address or a tenancy agreement on your phone. In a condo, the guardhouse may also check before letting a contractor up.

Ask how they plan to open the door and how the charge is worked out, since quotes depend on the lock and the job. Our guide to home service scams covers what to watch for. If the lock must be replaced, our door lock replacement page lists companies that do it.

Fire-rated main doors

If the lock is being replaced, check the door too. The Singapore Civil Defence Force (SCDF) says fire-rated doors minimise fire spread and uncertified hardware on a fire door may affect their ability to do so. A serial label near the hinges of the door or frame shows the fire resistance period, for example 30 or 60 minutes; if unsure, check with HDB for public homes or your Management Corporation Strata Title (MCST) for condos.

Since 2024, SCDF says a digital lockset installed on a fire door must be certified for fire resistance, either together with the door or on its own. Ask the supplier for the Certificate of Conformity (CoC): the brand and model must match, the lock's fire resistance must be at least the door's (a 30-min door can take a 30, 60 or 120-min lock), the product details should state a mechanical fail-safe feature so you can still unlock the door to leave if the battery dies, and the lock should be tested to SS 332 or EN 1634-1. SCDF does not endorse or certify products. More in our fire-rated main door comparison.

Keeping codes safe

Keep the mechanical key outside the home, with a relative or neighbour you trust, not in a drawer behind the locked door. Seal the main code in an envelope or keep it in a password manager.

Give each person their own code where the lock allows, so one can be deleted without changing everyone's. Skip codes built from your block number or birthdays, and wipe the keypad now and then so smudges do not hint at the digits. Thinking of a newer lock?
