Choose-a-Color Keyed Alike Lockout Padlocks

Padlocks come in a variety of colors for lockout identification compliance. Choose these locks if you need several locks that open with the same key. If the lock or key with the key number you want isn’t listed, order the “Other Key Numbers” and specify your desired key number.
Pin-tumbler key locking mechanisms are the most difficult locking mechanisms to pick. When choosing between padlocks with four or five pins, the lock with five pins is harder to pick.
