Keyed alike padlocks have the same key that can be used to open all padlocks from the same set. This type of lock is commonly used by maintenance personnel in charge of several machines or isolation points. With fewer keys on the keyring, it is easier to identify and use the right one.
Meanwhile, keyed different padlocks have different keys for each lock. It’s the ideal lockout solution if an employee commonly applies a single lock. It also ensures no risk of key duplication when numerous maintenance employees need to access the same piece of equipment.
