Master Keys Set

In the world of locksmithing, one tool stands out for its inherent versatility and usability—the master key. This specialized key set is designed with simplicity and effectiveness in mind, offering a range of benefits for users of all levels.

Occasionally, someone will want the locks they use in their facility to have “mastered” locks. This means that although all the individual locks have individual keys, there’s also a “master” key that will open all locks. A good example would be in a gymnasium locker room. If someone lost their key, the staff could still give them access to their locker, so they're not leaving the swimming pool in the nude!

How a Master Key Works

The locks have 3 pins rather than the usual 2 to make this work. The actual key aligns the first split in this set; the master key aligns the second split. However, the inclusion of the third pin and the second split reduces the number of possible combinations and, therefore, the key's complexity. This means they are easier to pick or decode. Additionally, the pinning patterns used in these “mastered” locks tend to be predictable and common, compromising their security.

Over the years, lots of these predictable and common pinnings have been recorded, and those patterns are what our master keys are based on, making them very effective try-out keys when working in the field.

The other master keys, such as our fire brigade keys, work because the fire service has maintained the same pinnings, so different forces up and down the country can ensure access to the fire service locks.
