If you're moving into a new home and have a traditional Nightlatch fitted an easy way to change the lock is to replace the cylinder. It’s a simple DIY job and you will need a screwdriver and a hacksaw to complete.

Suitable for use on timber/ wooden doors between 35 - 54mm thick.

Step 1 :

Identify the lock fitted There are slightly different ways to approach this depending on which nightlatch is currently fitted to the door, please read these instructions before proceeding to Step 2.

If you're swapping the cylinder on an ERA traditional nightlatch the screws are surface mounted on the inside these can be unscrewed and the cylinder itself pushed through the door on the outside.

Remember that the arm of the cylinder only needs to sit in the aperture of the lock, it does not need any pressure applying to push it in.

If you’re swapping the cylinder on an ERA Replacement front door lock it is the same as above but the lock is removed by unscrewing screws that are on the latch face of the lock. The lock then will lift off and leaving the fixing plate still attached to the door. The cylinder can then be replaced in the same way as the traditional nightlatch.
