EURO CYLINDER locks are a common type of lock found in most uPVC and aluminium doors. A euro cylinder lock can be fitted easily without the need for a locksmith and you should be able to obtain one that will fit any door.

DOUBLE CYLINDERS are found on uPVC and classroom doors. Keys can be used to open these double cylinder locks from both sides.


Stainless steel pins within the cylinder provide anti-drill protection where the steel from the drill bit is softer than the protective metal.
Anti-snap features help to prevent lock snapping (hammering the lock in a forced entry) but primarily leaves enough of the lock in working order.
Some locks can be picked open using a hair pin or a paperclip. Anti pick locks are designed so that it is almost impossible to open the lock in that way.
Lock bumping is a technique used to open a lock using a special key to jolt it open. Anti-bump locks have a specially made key and more pins.
Euro cylinders have the same dimensions and are easy to install and remove. The actuator in the centre needs to be turned with a key so that it lines up flush with the lock hole and then a screw in the frame of the door holds it in place.
1. Locate and remove the fixing screw on the side edge of the door.
2. Insert the key into one side whilst slowly turning the key to enable you to push the old cylinder out.
3. Measure the overall length of the cylinder and the dimensions either side of the centre hole.
4. With the key in the lock and the cam lined up with the cylinder, insert your new lock.
5. Secure the lock in place with the new fixing screw provided.
It is important to remember that the cylinder has an external and internal side which must be the correct way round when fitting the lock.
