In many Singapore homes—especially older HDB flats and landed properties—wooden main doors or room doors still have deadbolts that are 15–25 years old. Over time, the internal metal parts wear out from daily use and humidity, causing the key to turn stiffly, the latch to stick, and the door to become difficult to open or close properly.
A customer recently contacted us with this issue:
The lock can’t turn properly at times. The latch will not return fully, preventing the door from opening.
We inspected the lock on-site and found significant internal wear. Below is the complete step-by-step documentation of the replacement job we carried out in Singapore.
Customer’s initial view of the old faulty deadbolt
The old deadbolt with keys inserted is on the wooden door. The customer reported frequent issues with the lock turning and the latch not retracting properly.

Close-up of the 20+ years old lock

Old lock bolt extending fully (before replacement)
The old bolt was extended. Even though it could extend, internal wear made operation unreliable and frustrating.
The deadbolt mechanism was faulty after 20+ years, but the handle was still in good working condition, so we kept it because costs were reasonable.
Inside the old lock—metal dust showing heavy wear
Look at the metal dust accumulated at the bottom of the mechanism. This is clear evidence of long-term wear from the moving parts rubbing against each other.
Old vs New cross-hand comparison
Compare the new crosshand (top) with the old crosshand (bottom). Notice how the old one has expanded and deformed significantly over the years due to constant friction and wear.

This is after the new deadbolt has been successfully installed. The bolt now retracts smoothly and easily, solving the main problem.
