Mortise Lock Replacement in Singapore
Mortise lock replacement starts from $100 in labour at SG QuickFix, with the new lock charged separately. A mortise lock sits in a pocket cut into the door edge, common on main doors. A worn case or broken levers are replaced with a matching lock so the existing pocket can be re-used. Most replacements take 45 to 90 minutes.

Task guide
When this may be needed
- The deadbolt doesn't throw fully or sticks halfway.
- The handle turns but the latch stays out.
- The key turns but nothing happens.
- The lock makes a grinding noise.
- The faceplate on the door edge is loose or bent.
What the team does
The technician removes the handles, cylinder and lock case, and measures the case size, backset and faceplate so the replacement matches the existing pocket. The new case is fitted, the cylinder and handles are refitted or replaced, and the strike plate is checked against the latch and deadbolt. The lock is tested with every key, from both sides, and with the door closed.
Included in this price
- Removing the old mortise lock case
- Measuring and fitting a matching case
- Refitting handles and cylinder, and adjusting the strike plate
- Testing the latch, deadbolt and every key
Limits & price factors
The lock is charged on top of the labour price. Converting to a digital lock, enlarging the pocket for a bigger case and door or frame repairs are separate tasks.
The price covers a like-for-like mortise lock in the existing pocket. A case of a different size, a frame that needs the strike re-cut, and fire-rated or metal doors take longer. A photo of the faceplate on the door edge helps match the lock before the visit.
FAQs
Look at the edge of the door. A mortise lock has a long rectangular faceplate with both the latch and the deadbolt, because the lock case sits inside the door.
Sometimes a sticking lock only needs cleaning or a strike plate adjustment. Broken levers or springs inside the case usually mean the case is replaced.
A lock with the same case size and backset will. That is why the faceplate is measured before buying.
About 45 to 90 minutes.
