Anti-snap cylinders & rekeying
Anti-snap cylinders are commonly rated to TS 007 3-star or Sold Secure SS312 Diamond; the cylinder is sized to the door so it does not stick out.

What this covers
Replacing euro cylinders with anti-snap cylinders, or rekeying locks after a move or a lost key.
Before the locksmith arrives
- Wait somewhere safe and well lit, especially at night.
- Have ID and proof of address (or the V5C logbook for a car) ready.
- Do not force the door or window — frame and glass damage usually costs more than the lock.
