| Comment | This is pretty straightforward to do yourself if you have a few hours to read about how to change locks. Usually you will need a deadbolt, which needs to match "backset" depth with your existing lock (otherwise you have to drill a new lock hole. Ideal if you can match brand too but generally they actually are mostly the same size as each other so they fit the slot quite well. And then the Yale (nightlatch) cylinder is literally the easiest thing in the world to change. You don't need to change the lock just the cylinder, they cost maybe £8. |
