In reality, master keys do not exist; however, there are a number of exceptions. It is not the key that is really special, but locks that have been adapted to allow the key to work. This is normally intentional in the makeup of the said locks. Master keys normally exist where a suite of locks have been levered or repined so that an extra key can be used to open them all. The additional key in this case can be used to open all doors in an office building, hence being called a master key. Outside this suite of locks, this key is usually useless.

Are fire brigade master keys?

Keys used to open fire brigade padlocks and mortice are not master keys as the locks used on them are all made the same way. In some countries, for instance the UK, radar keys are used to open all disabled toilet locks. These too are simply normal keys, but that have been made to open a certain brand and model of locks. The same applies to fire brigade drop keys. Homeowners are recommended to have these keys as part of their keyset.

There are a number of lock manufacturers that make locks with true master keys, for example Fletcher, Lowe and a number of others. In this case, these locks are designed in such a way that they can be opened with both the standard keys and a special key for the whole range. The ZL, ZG and ZA keys are very good examples of these special keys. The locks in this range are usually used on garage doors. Although the doors all have different locks, there is one special key that can open all of them.

Other locks, for example those in LF range of lock have extra special keys but that are not 100-percent effective as not all the suites are mastered. Locks that are normally used on filing cabinets, desks and lockers, etc fall under this category.
