Euro Cylinder

You will typically find a euro cylinder style lock on a UPVC or composite door with a multi-point locking system.

Below is the euro cylinder profile and the typical style of key that will operate the euro cylinder locks.

Mortice locks

This type of lock is embedded (morticed) into the door and the strike plate is fitted to the frame. This lock is usually only fitted to timber/wooden doors and can only be opened with a key, from either side.

Sometimes 5 lever mortice locks are confused with the less secure 3 lever mortice locks. You can check this by looking on the faceplate of the lock, the number of levers should be stamped there.

For optimum security the 5 lever mortice lock should be Kitemarked and conform to BS3621. If it is, these details should be stamped on the lock faceplate. In fact, many insurance companies require these types of locks to conform to BS3621.

What is BS3621?

BS3621 is a British Standard that sets minimum performance requirements for thief-resistant locks, particularly those used on external doors and windows, and is widely recognized for property security and insurance purposes.
