Padlocks come with different keying options, namely: keyed differently, keyed alike, and master keyed. Keyed differently are individual security padlocks with corresponding keys. In short, a key for one lock should not be able to open any other lock.

A keyed alike padlock set, on the other hand, can be opened by a single key. The padlocks have the same locking cylinders, which makes it convenient for an authorized personnel to carry just one key for multiple padlocks.

High security padlocks with a master key actually have different locking cylinders just like padlocks keyed differently. The only difference is that this padlock set includes a master key that can unlock all the padlocks in the group, allowing a supervisor or superior to unlock a padlock in case of emergencies.
