Moved into a resale flat? Change the main door and gate locks first. You don't know how many copies of the old keys are still around.
Send a photo of the door edge and the old lock and we'll quote with a lock that fits. Buying your own? Send the photo before you buy. Locks come in different sizes, and we'd rather tell you now than after you've paid for the wrong one.
Workmanship carries a 3-month warranty.

Frequently asked questions
How much does it cost to change a door lock?
It depends on the lock and the door. Send a photo of the old lock and the door edge on WhatsApp and we'll quote from that, before anyone comes down.
Can you change my HDB gate lock?
Yes. Gate locks get rained on, so they rust and go stiff faster than door locks. Send a photo of the lock on the gate and we'll quote from it.
I've just moved in. Should I change the locks?
For the main door and the gate, yes. You don't know who still has a copy of the old keys. One visit can change both.
Do you supply the lock, or do I buy it?
Either. We can supply a lock that fits, or fit one you've bought. Send a photo of the old lock first so you know which size to get.
