Interchangeable Core A-3 Pinning Kit
This rekeying kit works with the A3 Interchangeable Core lock system.
Difference Between A2 and A3 Interchangeable Core (IC) Systems
The A3 shares some commonality with the more popular A2 system, but the main difference is the height of the lock pins. Each pin size comes in a different height than the A2 or A4 sizes. Therefore a number 1 bottom pin from a A2 or A4 system would not interchange with the A4 system.
