The Avocet ABS Mk3 has been around for a while now and is one of the most popular anti snap locks found around Yorkshire so I thought I would do a review.

As the name suggests the mk3 ABS is the 3rd generation of ABS anti snap lock. The ABS works in a different way to all other anti snap locks with its patented cam mechanism. The clever cam mechanism means that even if the cylinder is broken in the middle access to the multi point mechanism is still blocked. The ABS has been awarded the British standard kite mark and the BSI TS007 3 star rating, it also has the secured by design accreditation. It has 8 pins and a magnetic pin for pick resistance and unlike the mk1 and mk2 it also has pick resistant trap pins. The abs is also drill and bump resistant as well.

A lot of the earlier attempts to make anti snap locks by other company’s just involves a sacrificial cut in the lock cylinder meaning if the cylinder is attacked the front section will break off leaving the remaining part of the cylinder still locked and flush with or just set back slightly in the door so it’s not possible to get hold of the rest of the cylinder. Unfortunately it didn’t take long for people to work out that there are ways of bypassing the sacrificial mark and still snapping the lock at the cam. This is where the ABS seems to exceed other anti snap locks.

The Abs does still feature a standard sacrificial weak point like a lot of other cylinders but it also has a second weak point which is just before the cam. This means that if a more up to date snapping technique is used and both the first and the second weak spots are bypassed the cam mechanism will activate. Once the cam has activated it will seize the cam meaning it can’t be turned or removed from the outside. The seized cam will then block any access to the catch in the locking mechanism which is used to unlock the door. A nice feature is that if you are inside the property and the lock is snapped from the outside at the second weak spot even though the cam is seized the lock can still be operated with the key from inside which means you are not left locked in.

The Avocet ABS is available in all the normal sizes and also all the normal sizes of thumb turn as well. They can also be ordered keyed alike and in brass or chrome effect finish. One thing to watch out for is the cylinder handing, as the cylinder will only provide anti snap protection if fitted the right way round. The lock is clearly marked EXT on one side meaning this is the external side and should go to the outside. When ordering make sure you get the handing correct, normally they are ordered by giving the internal measurement first and the external measurement second but make sure you check this first with whoever you are ordering your locks from. The Abs comes with 3 keys as standard and a registration card. The registration card must be retained in order to obtain duplicate keys.

All in all I think this is probably the most secure cylinder on the market today. All the views and opinions in this post are my own.

    What happens if your outside the property and come back to find somebody has attacked your ABS Mk 3 and snapped both sections. Does this mean you are locked out of the property

      If both sections were snapped then yes you would be locked out. But it’s better to be locked out than come home to find you have been burgled.

    Hi,
    I was wondering what were the main features and improvements introduced in mk3 when compared to the good mk2 generation?
    My house is currently protected with mk2 range and I’m just curious if upgrading to mk3 would bring me high on anything except the mentioned trap pins?
    Thank you for your reply.
    Jim

      Hi Jim

      The only real difference is the added trap pins in the mk3 which make it more pick and bump resistant. The mk2 is still a very good and secure lock.
