This article is being written to help our customers understand the basics of a master key system and how it differs from rekeying or keying alike multiple locks. Hopefully after reading this blog post you will have a good understanding of the two and also be able to decide which system is best for your purpose. As always, Legacy ProCraft your Locksmith York Pa is working to educate and inform our community and customers about a wide range of lock and key, physical security and electronic security issues.
We will start with keying alike. It is mostly self explanatory and we covered rekeying in great detail in an earlier post so refer to that for more information. Keying a lock alike means having a locksmith York PA change the internal pins or wafers (typical on car locks and cabinet locks) so that one single key will operate multiple locks. The keys that operate all these keyed alike locks are the same. They have the same biting (cut pattern). This is what keying locks alike is, using a very simple explanation. A point to remember is the locks must be able to have the same key fit into them in order for them to be keyed alike and to be operated by the single key.
Master keying on the other hand is different. When a group of locks are master keyed than two or more different keys (keys having different cut patterns or biting) can open a single lock. The most simple master key system is called a level two system and we will use this system as an example.
Suppose there is an apartment building and each apartment needs to have a separate key that will only open the lock on one particular apartment unit, but the building manager needs to have one key that will open all the apartment doors in the building for maintenance and inspection purposes. Instead of the apartment manager carrying around a ring full of keys, the manager calls on the local locksmith York Pa for a master key system and then has a single master key to operate all of the doors. The keys for each apartment are called change keys.
Master keying is a mechanical access control system that can define who can enter which areas of a building. It controls access of personnel or employees to specific areas. Master key systems are primarily a solution for businesses and is seldom appropriate for residential homes (with a few exceptions such as construction master keying). Master key systems can be designed to provide access control for small businesses to very large commercial complexes.
