Is your front door lock snap-safe?

Most uPVC and composite front doors use a euro cylinder: the part you put your key into. Older and cheaper cylinders can be snapped in two, and once that happens the lock can be opened in seconds.

What to look for

Look at the face of the cylinder, by the keyhole. A cylinder that resists snapping is usually marked with one of these:

• TS007 3 star: the cylinder on its own meets the standard.
• TS007 1 star cylinder with 2 star security handles: together they make 3 stars.
• Sold Secure Diamond (SS312): tested against snapping and other attacks.

A quick check you can do

If the cylinder sticks out past the handle or its plate by more than a few millimetres, it gives an easier grip to anyone trying to snap it. A cylinder that sits flush is better.

What we'd fit

If yours has no marks, or you've just moved in and don't know who has keys, we can fit an anti-snap cylinder on the visit. Our £499 full set replaces the mechanism, lock and handles in one go.
