If the letters CR appear on the metal faceplate on the edge of your door or around the keyhole, that is the brand of your lock or cylinder. Sometimes the letters are small and worn and hard to read. That is fine: from a good photo we can already tell what type of lock it is.
How to identify what you have
Take three photos in good light:
- The edge of the door, where you can see the faceplate of the lock with its screws.
- The cylinder from the outside, straight on.
- The key, both sides.
From those we know whether it is a mortice or a surface-mounted lock, whether it takes a European cylinder and roughly what size it is. If you want to pin down the size yourself, use the lock cylinder size calculator.
What we usually do
- If the keys have been lost or the key is stiff, we do a lock cylinder replacement. It is quick and the lock stays in place.
- If the lock does not draw the bolt back, the latch sticks or the handle does not spring back, we try a lock repair.
- If it cannot be repaired or there are no spare parts, we replace it with a compatible one of the same size, from whichever brand best suits your door.
A word of advice
Do not wait for the key to snap inside. When a lock starts to get stiff, it is usually down to dirt, a tired spring or the door having dropped so that the bolt rubs. The sooner it is looked at, the simpler the repair tends to be.
