[xPost from] Interchangeable cores provide a simple and effective way to "change your locks" in a matter of seconds. An interchangeable core (or I/C) system can easily and painlessly be installed in place of your existing locks.

What is an interchangeable core lock

Locks with I/C cores have an easily removable core. Using a special "control key" the end-user is able to easily swap in a new core if keys are lost or a tenant moves out. This eliminates the need to remove the entire lock every time you are in need of rekeying your door locks. Instead, you are able to pull the existing core out of the door and swap in a new pre-pinned core. You can then take the removed core to your local locksmith to pin up at your earliest convenience. This system eliminates having to leave the door unattended, since you will be locking it up with the new core almost instantly.

What key protection is available
