Common problems
Key Turns But The Door Will Not Open
The key goes round freely (sometimes round and round), but nothing moves and the door stays shut.
Lost House Keys
Your keys have gone missing or been stolen, and you do not know who has them or whether they can find your address.
Locks Do Not Meet The Insurance Standard
Your policy asks for British Standard locks and you have no idea whether the locks on your doors qualify.
Euro Cylinder At Risk Of Being Snapped
Your uPVC or composite door has a barrel lock sticking out past the handle, and you have read that they can be snapped.
Changing The Locks After Moving In
You have just moved in, you have a handful of keys from the agent, and no idea who else still has one.
Lock Or Door Damaged After An Attempted Break-In
Someone has been at the door: the cylinder is broken, the frame is split, or there are marks around the lock.
