There are two general categories of Interchangeable Core Locks. Large formant and small format. In this lesson we will look at some of each. The main difference between the two is that the small format uses a smaller pin and you will need a special pin kit in order to work with them. The other major difference is that small format locks are interchangeable among the manufactures. For example you could remove a Best small format lock and replace it with a Falcon, Arrow, and Eagle or a number of other small format locks.
