Locksmith Keying Options: Different Types of Keying Options

Different Types of Keying Options

Locks and keys have been around for centuries. The following are some examples of different types of keying options and how they work:

Different Types of Locks and Keys

Locks that are keyed differently provide an individual key for each locking mechanism and the keys cannot be used interchangeably. For example, if there were five separate locks, five different keys would be necessary; one to open each lock mechanism.

Replicate Keys

Lock mechanisms that are keyed or re-keyed alike allow for multiple doors to be opened with that one key. Regardless of the number of locks that exist, they can all be opened with the same key.

Master Keys

Locks that are master keyed are made to allow very specific access levels for many key holders. A master key system, such as this one can significantly lessen the number of keys that need to be made. A person can possess one key that will let him or her access multiple doors, rather than having to give a different key to the person for every door that he or she must open, one key can be made to access all of these doors. It’s a very convenient system that also allows a different person to be given an individual key that operates only one door. As an example, locks can be designed with a master key so that five doors can be opened with one key, but keys can also be made to only open one of the five doors. This is a prominent system in hotel industry where each guest has a specific key to a specific room, but the housekeeping staff can enter all the rooms with one key.

Construction Keying

This keying option uses many cylinders that are temporarily operational with a single key, which tends to be the case on new construction sites. During the process, all cylinders on the site can be operated with one key. Once the job is complete, a specific transitional key is inserted in the lock, which then changes the access options. This ultimately prohibits the master key that was used during the construction to work in the future.

Three-In-One Keying

Three-in-one keying allows a person to change a lock combination without assistance. This is very helpful when a person has lost his or her key, but immediate entrance is necessary. As its name implies, each three-in-one keyed device includes three different keys, which are typically red, yellow and green. Such devices work in the following way: the green key is initially used to open the lock, but if that key is lost, the user can turn the yellow key in the lock and gain entrance. This process in and of itself changes the combination of the lock so that it can no longer be accessed with the green key should the latter fall into the wrong hands. If a similar situation occurs in the future, one can simply repeat the process with the red key, thus rendering the yellow key ineffective.

This keying option allows a person to change lock combinations without any assistance. Sounds nice doesn’t it? This option is very helpful especially when a person has lost his or her key, and immediate entrance is necessary. As the name implies, these devices include three different keys, which typically come in colors: red, yellow, and green. Here’s how these devices work: The green key is generally used to open the lock, if that key is lost, the yellow key may be used to open the lock and gain entrance. When the yellow key is used to open the lock, the key changes the combination of the lock so that it can longer be accessed with the green, should it fall into the wrong hands. If a similar situation occurs, one can then simply repeat the process with the red key, rendering the yellow key useless. Pretty neat system if you ask us!

One Way Cylinder Keys

One-way cylinder keys are an option that includes: one key that can open the lock, one key that can secure the lock, and a third key that does both. This is an ideal option when the owner wants certain people in charge of unlocking and locking the door, but also wants certain individuals to be able to do both.
