How does a master key work?

Question

A master key system references a group of locks, and the keys that operate them, which are related in a hierarchy with one key at the 'top', which will fit into a large number of locks; and a large number of keys at the 'bottom' which may only fit into one lock. The fewer master key levels, the more secure the system.

Can a master key open any lock?

When lock rekeying into a master key system, two keys are created: Change key: This key can open the master lock, but only the master lock. It cannot be used inside any other locks you have. Master key: The master key can open all locks you have in your residential or commercial property.

How does a master key work for different locks?

Master key system is a system that allows two or more keys to open one lock. Master keys will be able to open multiple locks. The greater the difference between the master key and the change key, the more master wafers will be needed. The more master wafers, the more possible keys can open the lock.

What is the difference between a master key and a regular key?

Some locks are designed to work with two different keys. The change key will open only that specific lock, while the master key will open that lock and several others in a group.

What is the purpose of a master key?

A master key is a cryptographic key (typically a symmetric key ( Symmetric Cryptosystem)) whose sole purpose is to protect other keys, such as session keys, while those keys are in storage, in use, or in transit.
