Keying Options Available
How do we prepare your order? If you have a more complex system, please contact us for a free estimate.
Keyed Different (KD)
Keyed Different (KD) – Each door lock is opened by its own unique key that does not open any other lock in the set.
Keyed Different is the standard keying default on Master Lock and American Lock door locks.
Keyed Alike (KA)
Keyed Alike (KA) – All door locks in the set are opened by the same key. This option provides “same key” convenience and eliminates the need for multiple keys where numerous door locks are used. KA in the product number (ie 3KA) designates that the products are Keyed Alike. In some cases the customer can select a key code for the KA locks
Master Keyed (MK)
In a Master Keyed system, a master key opens all the locks in the system although each door lock also has its own unique key. This permits organizing master key systems along departmental or other functional lines to allow supervisory or emergency access. If the customer is adding on to an existing MK system, please specify the master key code.
