ABS Bump Resistance

The principle of a cylinder lock is different height pins that, when raised to a certain level, by different height cuts in a key, they all line up to give a shear line enabling the key to be turned.

The principle of bumping is inserting a specially cut key, and "bumping" the key to make the pins jump apart whilst turning the key and so enabling a break position.

The video below demonstrates a few of the many security features of the ABS cylinder door lock.

The ABS cylinder uses double pins, (a pin within a pin), in each position to make bumping more difficult. You can see the pin within a pin when the key is turned in the video.

It also has one pin (the pink one in the video), which is in a random position, that sits across the shear line but is not touched by the key. This means it cant be bumped by the key.

This pin is then drawn in the opposite to the other pins by a magnet, which means to be able to bump this cylinder eight individual pins, some inside others, have to be bumped in one direction and the magnetically drawn pin in the other.

It is worth remembering that to bump a lock you have to have a key blank that fits the lock to make a bump key.

ABS keys are different to normal cylinder keys and we do not supply key blanks to anybody!
