What is a master key system

Master keying is used because it allows those who must have access to many locks such as Landlords with numerous properties, Realtors, Property managers, Schools and government buildings, to name a few, to carry only a few keys. This gives them access to any building or group of buildings in which they may need to access with the use of one key, as opposed to a large ring full of keys. A master keyed lock system is one in which locks are designed not only to be opened by their individual keys, but also by a special master key that opens some or all other locks in the system. It is not usually possible to tell by inspecting a key or a lock from the outside whether it is part of a master system or not as it is the pins inside the lock that determine which key will open specific doors. A locksmith, with the use of a specific pin set up, can create two keys, one key is known as a pass key and the second key, known as the master key. A pass key can give someone access to some doors while the master key will open all doors. This method works well for someone who may have employees, for example, that are allowed into the storage room but not into your office. For a Realtor or Property manager this system could work well in that one master key could open every front door on your property list. This would give you the convenience of handling just one key for every property. For facilities requiring a higher level of security, we recommend that master key system set ups be accompanied by other mechanical mechanisms, as there is a slight risk of vulnerability within a master key system. We will not discuss that vulnerability here so please call to set up an appointment to discuss your special security needs. Overall, a master key system is a convenient and timesaving system for those who deal with multiple locks on a daily basis, however, a master key system is only as good as the locksmith who sets it up.
