The d12 is a medium security pin tumbler made by ASSA for residential or commercial use. It is intended as a successor to the ASSA 700 series which dates back to 1948. It features six pins and numerous security improvements over the original cylinder, including a paracentric keyway and patented key profiles.

Disassembly instructions
Due to the atypical construction of this lock, disassembly using a follower is not recommended.
- Remove the Torx screw on the tailpiece and the wafer beneath it.
- Unscrew the retaining cap on the rear of the plug.
- Unscrew and remove the closing rod over the pin chambers (be careful not to allow springs to escape).
- Remove the driver pins and springs. They are all the same so there is no need to keep them in order. Key pins cannot fit through the top chambers.
- Slide the plug out of the housing.

The ASSA d12 may be vulnerable to one or more of the following:
