How To Prevent Cylinder Lock Snapping


New standards for euro cylinders have now been developed to test them against the most common known methods of attack. The new British Kitemark TS007 3 Star rating and Sold Secure Diamond grades mean that the cylinder has effectively passed snapping and forced entry tests.

The ABS snap secure euro cylinder has Unique Patented Snap Secure Technology that blocks out intruders making it the ultimate door security upgrade.

ABS is the only retro-fit high security euro cylinder that has attained the Sold Secure Diamond accreditation and has Secured by Design and the TS007 3 star British Kitemark rating.

An ABS lock will quickly swap with your current lock with no extra cutting and drilling to your door!


ABS has layered protection which is proven to effectively combat against lock snapping attacks.

1. Break-Off Front!

A front sacrificial section which will break off if attacked. The lock will still be operable with the key on the remaining part of the cylinder.

2. Snap Secure Technology!

ABS takes lock security to another level with it's patented system that locks the cam into position if the second portion of the ABS lock has been snapped.

3. A Total Barrier!

If sections one and two are removed in an attack the patented locking cam and blocking mechanism will provide a total barrier against entry.

The ABS lock will still be operable from the inside of the property allowing the property owner to securely open and close from within.

ABS features a Patented proven cam blocking mechanisim that combats against lock snapping attacks. ABS snaps when attacked but ensures that it provides a barrier to entry. No other lock on the market provides this level of protection.


Most importantly an ABS lock can be installed in a door in minutes as it has been specially designed to ensure that no other modifications are required.


Some locks require the help of a strengthened collar or cylinder guard - whilst these measures may help they do not provide the proven security levels of an ABS snap secure euro cylinder. And importantly many of these require extra material to be removed from the door for installation - this means that the door strength can actually be compromised!


Please note that locks that comply with British Kitemark TS007 "One Star" rating have not passed the snapping tests included in the 3 Star accreditation. One Star rated locks need a Two star rated security handle or cylinder guard (at additional cost and often further door modifications) to be classed as a true anti-snap solution.


Anti-snap lines alone do not secure. They don't always snap at the desired location to provide the protection required - there is a reason why the majority of these locks require additional cylinder guards and security handles. The ABS snap secure lock has reached the highest standards on the market and can be installed without extra security back up.
