My key turns but the door won’t lock — what’s wrong?

Usually a worn or failed multipoint gearbox, or the door has dropped on its hinges. Matt can diagnose and repair it, often on the first visit.

What is lock snapping?

It’s a technique burglars use on standard euro cylinders. Fitting an anti-snap 3-star cylinder is one of the cheapest, most effective security upgrades you can make.
