Keyed Different (KD)
Each 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 padlocks.
Keyed Alike (KA)
All padlocks in the set are opened by the same key. This option provides "same key" convenience and eliminates the need for multiple keys where numerous padlocks 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 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.
MK in the product number designates that the products will be Master Keyed.
If the customer is adding on to an existing MK system, please specify the master key code.
The cylinder in rekeyable padlocks can be removed in order to (a) change the pinning or (b) replace the original cylinder with a new one, restoring security quickly and economically. This is ideal for situations where keys are lost or stolen. Products with this option can be identified by "rekeyable" in the item description. Rekeyable padlocks are available Keyed Different, Keyed Alike, or Master Keyed.
- Quickly restore security – should lost keys or employee turnover compromise your padlock system
- Save money – replace cylinders instead of locks

Interchangeable Core Locks
Interchangeable core padlocks and door locks don't require disassembly in order to change the cylinder. The figure-8 interchangeable cores (IC) can be removed and replaced with a single control key.
This convenience addresses common security issues:
