Common Questions

Can I order multiple padlocks that all open with the same key?
Yes. Padlocks that can be opened with the same key are called Keyed Alike (KA)

Can I order new padlocks keyed alike to match a padlock key code I already have?
Yes. We can supply Master Lock, American Lock, ABUS, PACLOCK, and Enforcer padlocks keyed to a specific key code. Some restrictions may apply.

What are keyed differently (KD) padlocks?
A group of Keyed Differently (KD) padlocks will have randomly selected key codes for each lock so that the key from one lock will not open other locks in the group. The number of key differs depends on the the number of pins in the cylinder. The only way to guarantee that there will be no duplicate keys in a group of padlocks is to request that the padlocks be registered (not available for all padlock models).

What are master keyed (MK) padlocks?
A master key (MK) is a unique key that will open all padlocks in a group of padlocks. A group of padlocks that open with a master key is called a master key system. Master keying is not the same as keyed alike. This is a common misconception. See keyed alike above. REQUEST A QUOTE for master keyed padlocks.
