Principles of operation

The ABUS 80TI/50 padlock is a standard pin-tumbler lock with a paracentric keyway, and six pin pairs. While the key pins are the traditional design, the driver pins are various security pin shapes: spooled, serrated, and special T-pin shape that suggests it is intended to provide protection from bumping attacks.[2]

When all the pins are lifted to the shear line, the plug can rotate clockwise.

The ABUS 80TI/50 can only be opened by rotating the plug clockwise.

Disassembly instructions

The ABUS 80TI-50 cannot be disassembled non-destructively; to disassemble, you have to drill open the seventh pin chamber and remove the retaining pin and spring. Be warned, you can't use a follower or a shim, maybe a modified pinning shoe will work. If not, the driver pins will shoot in the empty chamber when you pull the plug out.



The ABUS 80TI/50 is vulnerable to "over lift" attacks, where the entire pin stack can be lifted, using a comb pick, into the driver's pin chamber, allowing plug rotation.

The ABUS 80TI/50 may be vulnerable to one or more of the following:
