How Internal Door Locks Differ from Front Door Locks
The lock on your bedroom or bathroom door is almost never the same type of mechanism you would find on your front door. Front doors in Abbey Wood properties typically carry a Yale-type nightlatch, a five-lever mortice deadlock, or — on newer builds and flats — a multipoint lock operated by a euro cylinder. Internal doors use something far simpler: usually a small tubular latch with a turn-button or a coin-slot release on one side. Bathroom bolt sets, privacy latches, and bespoke-style knob sets with a push-button lock are all common. Because these mechanisms are designed for privacy rather than security, they can be opened by an experienced locksmith without any destructive force in the vast majority of cases. The techniques are non-invasive, and when carried out by someone who works with these locks regularly, the door and its frame are left completely intact.
That said, internal doors in older Abbey Wood properties — particularly the inter-war and post-war housing stock between Wilton Road and Mcleod Road — can present their own quirks. Swollen wooden doors, warped frames, or seized latches caused by years of humidity in bathrooms can complicate what looks like a straightforward job. Our technicians assess the door and mechanism before attempting anything, so there are no guesses and no unnecessary force.
