In this first case, we were tasked with changing HDB BTO room door lock. When this unit was returned to the owner, the owner realized that the entire lock was completely missing, for unknown reasons. So we re-installed the full lockset, along with the side latch, as shown above. The last panel shows the completed installation, along with the 3 new keys provided.
In this particular case, the latch of the old HDB BTO room door lock did not retract, when the handle was pressed down. This can be seen in panel 1. We also had a lot of difficulty while removing the lock. Upon investigation, the latch of this lock was found to have rusted badly. What had conspired was that the handles had also corroded, which caused them to become stuck. Luckily, we managed to replace the lock successfully. We advised the customer on how to maintain the lock with WD40. Owing to its anti-rust qualities, WD40 is excellent for lock maintenance.
This lock type is commonly used for room doors in new BTO flats in Singapore. Other examples of commonly used lock types include the round doorknob, lever handle and cylinder lock.
