Deadlocks

A deadlock is a single-throw, key-operated bolt that adds a strong locking point to internal and external doors. Choose from BS 3621 Kitemarked 5-lever deadlocks, standard 3- and 5-lever cases and euro profile deadlocks. A deadlock pairs well with a sash lock higher up the door.

Deadlock buying guide

What is a deadlock used for?

A deadlock throws a solid bolt that can only be moved with a key, so it cannot be slipped or forced back like a latch. It is often fitted below a nightlatch or alongside a sash lock for extra security.

How do I measure a deadlock?

Measure the backset from the door edge to the centre of the keyhole, and note the case size. UK cases are commonly 64mm or 76mm.

Do I need a British Standard deadlock?

For external doors and to satisfy many home insurers, look for a BS 3621 Kitemarked 5-lever deadlock. Euro profile deadlocks rely on a separate cylinder.
