What is Lock Snapping?

Research from Evander Glazing and Locks 2013 Home Security Survey has revealed that 85% of home owners are still unaware of lock snapping.

Lock snapping is a forced-entry method, where force is applied to standard euro cylinder locks and the lock is snapped. Once this damage has been done, the perpetrator can access the locking mechanism to open the door. It’s quick, easy and requires very little equipment, making it a very simple way for thieves to access your home.

How do I know if I have vulnerable locks?

If you need to move the handle up to lock the door, it’s likely that you’ve got a euro cylinder lock fitted to your door. And if the door was fitted before 2008, it’s likely that your door doesn’t have an anti-snap lock fitted, which is currently the only way to protect yourself from having your locks snapped. Essentially, the old-style euro cylinder lock has a weakness in its design, making it easy to snap when pressure is applied.

Many of you reading this will probably think that you don’t need your locks changed and it will never happen to you. When this was first highlighted to lock manufacturers in 2006, the technique was only used by burglars in the Leeds/Yorkshire area of the country. However, since the technique was featured on the BBC in 2013, we have seen a dramatic increase in the number of lock snapping incidents throughout the country.

To help you understand the extent of the issue, Evander repair over 60,000 homes a year from the effects of burglary on behalf of our insurance clients. Eighteen months ago 1 out of every 20 burglaries in London were the result of lock snapping. Now that number is more than 1 in 5.

The ‘Anti-Snap’ SolutionEuro Double Cylinder Lock

To combat the problem of lock snapping, many lock manufacturers have come out with their own version of an anti-
snap lock. As you’ll see from the picture below, an anti-snap lock generally has a purpose-built weak point at the front of the lock (on the picture below, it’s the thin black line towards the front of the lock). In reality, the name anti-snap is a bit confusing. The lock is actually designed to snap, but in a place where the security is not affected. This manufactured weak-point saves the important part of the lock itself, as without it the lock would snap where the thick black line is. This is the part which actually secures the door and should not be compromised.
