All locks fitted in households today fall in to 3 different categories of locks.


Five-lever mortice deadlock conforming to BS 3621

This is the typical lock fitted to most wooden doors to comply with Insurance companies.



Key-operated multi-point locking system

This is a rim-locking system that bolts the door into the frame and offers a higher level of security.




Rim automatic nightlatch with key-locking handle

These offer extra security at night, allowing homeowners to lock their doors more securely from the inside.
