Lock snapping is a burglary technique which involves snapping a particular type of lock cylinder in two by applying the right amount of force and removing the outside part to expose the locking mechanism.

Euro-cylinder locks are likely to be fitted to the majority of external doors in your property and some offenders have developed a way of overcoming them to then gain access. There are ways that you can reduce the opportunity for a Euro-cylinder burglary at your home:

• Ensure the locks on your doors are tested and approved to SS312 Diamond Standard.
• Ensure locks and handles follow British StandardsTS0007 (3 star cylinder, or 1 star cylinder and 2 star handles).

You can change cylinder locks yourself, but it is vital that they are measured properly to ensure the right size for your door. They should not be fitted so that they are left protruding from the door unit or handle. 

The best advice is to have them fitted by an accredited locksmith who is a member of the Master Locksmiths Association and consider obtaining more than one quote.
