Many uPVC and apartment door locks have a design weakness that lets them be snapped in seconds. Here’s how to check yours.

Does Your Cylinder Stick Out?

Take a look at the outside of your front and back doors. Measure how far the lock cylinder sticks out from the door handle.

The rim of the cylinder should sit less than 3mm from the handle faceplate. If it protrudes further, your home could be vulnerable to being broken into in seconds.

Not sure? Send us a photo.

Take a picture of your lock and send it via our contact page — we'll tell you if it needs replacing.
