Changing Door Cylinder - Help

donal7

Hi,

I'm looking to replace the cylinder on one of the doors. I read that you begin by removing the cylinder retaining screw which I can't seem to see?

I want to replace the cylinder with a more secure cylinder (have read about lock bumping). Can it be done with this type of setup and can you suggest where is best to purchase a new cylinder and how much roughly for one (one where a special card is required to get a copy of the key).

I have attached pics of the current setup.

Thanks in advance.

I've only ever changed a cylinder on a PVC door, and in that case the cylinder retaining screw was located just above where the PAT GB is in your pic. Obviously different doors can work differently, but what happens when you remove the two visible screws, is it possible it removes the front plate only and reveals more?

Your type of lock is called a eurocylinder. Keyed one side/thumbwheel on the other. You could phone around the locksmiths to find out about bumpproof euro cylinders.

A security key (that you need a registration cert in order to be allowed to) won't necessarily prevent someone getting a blank form of the key then making a bump key.

If you remove the two screws of that vanity plate (in your middle photo), you'll reveal the lock body proper. There'll be a single long bolt just above PAT GB. Remove it and you can slide the cylinder out in the thumbwheel side direction (you'll have to rotate the thumbwheel to align things so the cylinder comes out. It's not too fiddly though)

Thanks delly & antiskeptic for the replies.

I removed that panel and found what I was looking for.

Thanks to you both
