More Info

An interchangeable core has many advantages over a any other keying system. Interchangeable cores provide for flexibility to easily and quickly exchange the core of  your lock without taking the lock apart. This can be very useful if a key is misplaced or if someone unauthorized got hold of your key and can gain access to the wrong places. Interchangeable cores are great protection.
