What are Interchangeable Core or IC door locks?

IC door locksInterchangeable Core Locks or IC door locks have a removable core with its hallmark ‘figure 8’ that can be swapped with other cores as needed. So, if you want to rekey your lock, you can simply do it by extracting the current core and replace it with another.

The extraction of a core from one lock and then installing into another requires a special control key and but you don’t need to disassemble any part of the lock to change the lock cylinder. This means you can easily and immediately rekey your locks (your locks would be as good as new) if you have fired an employee or when your keys are lost or stolen, without having to call a locksmith.

Applications and benefits of IC door locks

IC door locks work best for high security situations where you may require frequent and also immediate rekeying capability; for example, office buildings, apartments, dorms, schools, large campuses, hospitals and especially with exit hardware and all-glass doors, where extensive efforts are needed to rekey.

  1. Fast rekeying; saves time, efforts and money in rekeying or repining locks
  2. All you need is a single control key to pull and remove the core
  3. No need to disassemble the lock
  4. No need to hire a locksmith or use special tools
  5. Readily integrates with master key systems with any type of core, standard or interchangeable
  6. Come with restricted keyway option, thus offering amazing security (with restricted keys no one can copy your keys without your approval.)
  7. Can be easily integrated into your current conventional cylindrical locking systems
  8. Commonly used in master key systems

IC door locks are available as Small Format Interchangeable Core (SFIC) and Large Format Interchangeable Core (LFIC). While the face of both cores resembles figure 8, there is a difference. In SFIC, both circles (plugs) are same in size whereas in LFIC, the bottom circle is larger than the one above. Here’s a quick rundown on both types.

SFIC locks are available in six and seven pin length versions and you can use the same keys for either version. Locks with small format cores offer more security as they are harder to pick and also offer more possibilities with mater keying. LFIC locks are available in six pin variety and they are also easier to take apart than SFIC locks.

IC door locks are great for commercial use. And you have to keep in mind that although IC door locks may cost you more than your traditional non-core lock systems, the investment is really worth it due to all these benefits, including security and rapid rekeying ability and convenience.
