Interchangeable Core
An 'interchangeable core is a lock core that can be replaced without fully disassembling the lock. Interchangeable cores typically come in the "Figure 8" form factor. They are characterized by their ability to be changed by the end user rather than a locksmith.
Function
The opening and closing of an interchangeable core is exactly the same as it would be on a full form factor lock of the same type. (For example, a pin-tumbler lock.)
In most interchangeable cores changing of cores is done by using a special key known as a "Control Key" or "Interchange Key". This key functions as a normal key would, but it unlocks the holding mechanism for the core, allowing it to slide out.
Other interchangeable cores (mostly on padlocks) use a single retaining screw below the clasp to hold the core in place, however there is debate about if this is still technically an interchangeable core.
Security
Interchangeable cores have both security benefits and downsides.
The addition of an extra one or more pins controlled by the control key leave at least one extra possible correct position for the lock. Making it easier to pick.
However, the time saving benefits of an interchangeable core and the fact the work does not need to be completed by a locksmith mean that in the event of a key breach, locks can be changed quickly and efficiently by staff rather than a professional locksmith.
