hi everyone, my HDB flat has window grilles facing a common corridor. The window grilles have a keyed lock (i.e. can be locked with a key) but my mum is concerned that the lock is quite generic and therefore either very easy to pick, or common key sets exist (i.e. there may be other people with the exact same key which can open the lock).
My initial thought is therefore to buy another, if possible, more secure lock to additionally lock the window grilles. Perhaps one that is pick-proof.
Any suggestions on my problem ? Or suggestions where to get grille locks ? Thanks.
