What is the difference between the A4 and other Best Interchangeable Core systems?

The A4 is similar to other Best IC systems in many ways. Keying and the design is all very similar. The difference lies in the cut depths on the key blank and corresponding pin height. A number one bottom pin in the A4 system does not share the same height as a number one lock pin from an A2 or A3 IC system. The A2 is by far the most popular, but when servicing the A4 system, this pinning kit is required.
