When we're speaking about residential and commercial security and safety needs, keys will almost always be on top of the subject. Master keys are commonly used in commercial setups where the master key holder may have a key to their office's main door that can also open the bathroom, or a maintenance staff may have a master key that opens every door in the same building.

Apartment owners uses master keys to open each door of their rented apartments, then occupants have their keys for their unit being rented. Other common areas in the apartment can also be opened using this key including the main door of the entire building. It cannot be used to open another unit.
