The master key features a common pattern for a specific style of lock that is used across a specific series of locks in an apartment complex. The master key is used to enter everyone’s apartment. Typically, the key is held by the property manager or a maintenance man for the property. The master key is designed with a cylinder lock and a cam. The key can work with a variety of locks.
The design of a master lock
There are two different types of keys that can work in a typical lock. There is a traditional key and then a master key. The typical lock is a cylinder design. A pin and tumbler design is one of the most commons styles. The master lock comes with a cylinder lock that turns a cam. The cylinder or plug is turned in one direction as the cam pulls the bolt to open the door. The plug turns and the cam releases the bolt. The spring will snap back into place once cam is released. The master key is inserted into a lock where the key notches raise all of the pins so that there is a line made directly to the third pin. The space created allows the key to turn in a different way. There are two different ways the pins can be positioned to complete the turning process. If the pins do not line up properly, the key doesn’t work properly in the lock. The key will work properly when turned if all of the pins line up correctly. The pins in the key are not paired. There are three per sequence, and the third pin is called a spacer.
Advantages of having a master key
The master key consolidates multiple keys for a property into one set of keys. Instead of having multiple keys, a master can be used. Multiple keys are ideal for employees in a setting where they must gain access to a property. Landlords who need access to all units will access the keys. A tenant who may have to have access to more units will have a key to unlock more units in a property. Custodial workers can be used for janitorial purposes.
The master key eliminates the need for one to carry too many keys at one time to gain access to an apartment building. The master key is designed work with a group of locks. The person can use a master key with units or spaces where the third pin spacer is exactly the same in design.
