CLIFF

CLIFF is a toolbox for building and maintaining A2 Small Format Incerchangeable Core lock systems. It can be used to maintain an inventory of keys and cores, who has what keys and where cores are installed, and generate new changes or cores based on your existing system. It also allows for the reverse-engineering of cores to determine what keys operate it, and make finding (or creating) key crossover as easy as a click.

CLIFF is available as a stand-alone or Mercury-integrated web application.
