Door lock replacement in Singapore

Door lock replacement in Singapore covers everything from changing a worn lockset to fitting a digital lock on an HDB main door. Before booking, say which door and gate the lock is for, whether you want a like-for-like replacement or an upgrade, and whether you are supplying the new lock. Then compare quotes that state what is included.

Common lock jobs

Most lock jobs fall into a few groups. Knowing which one you need helps the handyman bring the right parts and give an accurate price.

If you are locked out, that is an urgent job, and the priority is safe access without unnecessary damage. Ask about call-out charges before the technician arrives, and be ready to prove you live at the address.

Replacing a lock like for like

The simplest job is replacing a lock with one of the same type and size, so it fits the existing holes in the door. Take a photo of the lock from both sides and the edge of the door, and measure if you can. Share these with the handyman so they can confirm compatibility.

If the new lock is a different size or type, the door may need new holes or the old ones filled. This takes longer and may affect the look of the door. Ask whether this is needed and how the door will be finished afterwards.

Digital locks

Digital locks are popular for main doors and gates in Singapore. They need a suitable door thickness and structure, and some models require modifications to the door. Ask the installer to check the door before you buy, and confirm whether the lock needs batteries, a mechanical key backup or a mobile app.

Some digital lock retailers bundle installation with the lock, while handyman companies may install a lock you bought separately. Compare the total cost and the warranty for both the lock and the installation. Ask who to call if the lock malfunctions, and what happens if you are locked out because of a dead battery.

For HDB main doors and gates, check any rules that apply to changes on the corridor-facing side. The HDB information on renovations is a useful reference. In condos, management may have rules about main door hardware.

Security and keys

When you move into a new home, changing or rekeying the main door lock means previous owners or tenants cannot use old keys. Ask how many keys come with the new lock and whether more can be cut. For digital locks, set new codes and remove old access cards or fingerprints.

Fire safety matters for main doors. Do not fit a lock that makes it hard to leave the home quickly in an emergency, and keep a way to unlock the door from inside without a key. Ask the installer how the lock opens from inside.

How lock work is priced

Companies price lock work per job, often with separate rates for repair, replacement and digital lock installation. The lock itself may be included or supplied by you. Extra work, such as modifying the door, fitting a gate lock or attending an emergency lockout, usually costs more.

The published rates further down this page come from company websites in the HomezyPro directory, one matching rate per company with its source and capture date. Check each source for whether the lock is included and what the price covers.

• Is the lock included, or do I supply it?
• Is door modification or hole filling included?
• Is there a call-out or after-hours charge?
• What warranty applies to the lock and the installation?
• Is GST included?

Preparing for the visit

Have the new lock, its instructions and all parts ready if you are supplying it. Clear the area around the door and make sure the technician can work on both sides. If the job is on a gate, check that it can be opened fully.

After the job, test the lock several times from both sides, with all keys and, for digital locks, every code and access method. Check that the door closes smoothly without forcing. Keep the receipt, the warranty card and spare keys in a safe place.

Other door and window repairs

If the problem is with the door itself rather than the lock, such as a sagging hinge or a door that no longer closes properly, the door and window repair guide explains what to ask. A lock may stick simply because the door has dropped out of alignment, so it is worth checking the hinges before replacing a lock.

Door lock questions

Can a handyman replace a door lock?

Yes, many handyman companies replace locks and install digital locks. Share photos and measurements of the existing lock so they can confirm compatibility and bring the right parts.

Will a new digital lock fit my HDB main door?

It depends on the door's thickness and structure and the lock model. Some locks need door modifications. Ask the installer to check the door before you buy.

Should I change the locks when I move into a new home?

Many people do, so that previous owners or tenants cannot use old keys. You can replace or rekey the lock, and for digital locks reset all codes and access methods.

What if my digital lock battery runs out?

Many digital locks warn when batteries are low and have a backup, such as a mechanical key or an external power option. Check the manual for your model and keep spare batteries at home.
