Mortice lever locks (sometimes called mortise locks) are commonly fitted to wooden doors but can also be found used in steel, aluminium, and composite doors. They are locked from both the inside and outside with the key which throws the deadbolt. By definition, a mortice lock is fitted (“morticed”) within the door, rather than being fitted to the face or surface of it.

There are multiple types of lever lock in use in the UK. Dead locks (mortice dead locks) are operated by a key only whereas sash locks (mortice sash locks) feature a dead bolt and a latch which is operated by a handle (often a lever handle). Both lever locks with throw the dead bolt into a strike plate. The strike plate on sash locks also accepts the sprung loaded reversible latch.

Lever mortice deadlocks can be used for fitting to front or back doors and to internal doors and external doors, but we’d always recommend fitting a British Standard BS3621 product to external doors for maximum security. You should also check with the houseowner’s insurer’s requirements on both residential properties and commercial properties. You may find lever locks fitted to commercial properties but cylinder lock cases operated by a cylinder or pin tumbler lock are more common mortice locks fitted in commercial environments.

Lever mortice door locks are commonly used for internal doors too. These tend to be 3 lever mortice locks where the requirements for security and burglary prevention are lower.

When replacing an existing lever mortice lock, you may find that your replacement mortice lock is larger than the one that you are replacing. This may be because you are improving security, such as upgrading to a lock with thicker, anti-drill hard steel plates or because the forend length, forend width or the design of the lock has changed. The hole for the lock can normally be made larger with a hammer and chisel. This can also be the case for strikes, which may have changed design.

Please always ensure that your door is sufficiently thick to accommodate the mortice lock that you are fitting. The Master Locksmith Association recommend a minimum thickness of 44mm.

A lever mortice lock prevents a door from opening by throwing a bolt from the lock into a metal keep or strike, fitted to the frame. Once the bolt is engaged in the keep, a hinged door is prevented from being opened. A mortice lock bolt is locked or unlocked from either the inside or outside by a key. Inside the lock, there is space for the bolt to be retracted. If the cuts in the key match the levers inside the lock, the user will be able to turn the key to throw (to lock) or withdraw (to unlock) the bolt. If the wrong key is used, the levers will not line up and the lock will not operate.
