Most modern doors are locked using a euro cylinder. The cylinder can be replaced by removing the securing screw, which is usually fitted through the faceplate on the side of the door.

This screw head is normally the widest head, in comparison to the remaining screw heads on the plate.

Once the screw has been removed, then you need to put the key into the cylinder and rotate it to either 10 to 12 o’clock or 10 past 12 o’clock, which depends on which side of the cylinder you have put the key into.

As you try to pull the cylinder out of the door, you may have to rotate the key slightly to align the lock to remove it.

If you are still struggling, it could help if you slacken the screws which secure the handle to the door, this will allow you to move the cylinder from side to side which also helps you to release the euro cylinder.

When replacing the euro cylinder, it pays to lubricate it prior to installing it, by using graphite powder only.

We recommend you avoid using any type of oil, because oil attracts dust, which can act as an abrasive and can wear out the internal cylinder’s pins. Finally, it is important not to use a battery screwdriver to secure the screw as it can pull the cylinder out of true, which will cause the cylinder to fail, always use a hand driver and do not over tighten the screw.
