Popular Locks Explained


There are many different types of locks on the market today.  The question is "Which one do you need"?


Below is a list of the main types of locks you will find on doors to your property with the correct terminology.


Also, follow the links at the bottom of the page to other ideas for security.

Rim Cylinder.  This is more commonly known as a "Yale" lock.  These are normally found on timber doors and is the most basic form of security measure for a property regarding locks.  This cylinder is used with a nightlatch of your choice.

Night Latch.  Simplistic, it gives a latch securing the door at a single point.  Mounted on the inside of the door, it is used in conjunction with a rim cylinder to operate the latch from the outside.  It is used mainly on timber doors. This type of latch rises from the most basic up to high end security.

Euro Cylinder.  These are mainly used on UPVC doors and secure multipoint mechanisms.  They are the most common lock on a residential property today.  This type of cylinder can also be used with Euro Mortice Cases on timber or steel doors.  

Euro Thumbturn cylinders (escape locks).  These are used in the same way as euro cylinders.  Useful so that you don't have to look for a key when opening a door on the inside of a property.  This type of cylinder is ideal for HMO property and letted bedrooms.

Mortice Deadlock.  Available with 2, 3, 5 & 7 levers and with 2.5" & 3" cases.  If considering fitting a deadlock, we recommend that a 5 lever BS3621:2004 should be fitted to timber external doors and main exit doors on a residential property in order to comply with your insurance regulations.  These locks are particularly useful to bolster security of a timber door where only a "Yale" lock is being used.

Mortice Sashlock.  These are the same as Mortice deadlocks with the exception of having the capability to use handles.  Generally not used to bolster the security of a "Yale" lock.

Euro Mortice Case.  These types of locks work in exactly the same instances as the Mortice locks.  The difference is that they are operated with a Euro cylinder.  Eespecially used in conjunction with Euro thumbturn cylinders in HMO ans letted bedroom accommodation.  They come as a sashlock, deadlock and profiled night latches.

Multipoint Locks.  This is the "de-facto" type of locking system you will find on a UPVC door.  The system comprises of a central gearbox / casing, hooks and / or rollers above and below the centre normally towards either end.  A well designed and strong locking system giving you probably the most secure defence against an attack.  The system is operated with handles and is locked / unlocked with a euro cylinder.
