Installing a Master Key System at Home: Pros and Cons

Home is supposed to be our safe sanctuary. Our homes must be equipped with proper locks of supreme security.

In recent years, with the advancement in technologies, a new system of locking has surfaced, which is a master key system.

This type of locking system acts like a spare key in case you lose the primary key of your house or vehicle. If on any day you lock yourself or forget the key inside your home, there is no need to call up a locksmith. This master key can easily save you from this hassle.

What Is a Master Key System

Master keying refers to a mechanical locking system used throughout a building, whereby one key can access multiple locks. Master keys function with lock models that are designed to work with two completely different keys.

A change key is used to exclusively open a specific lock, while a master key is used to open the respective lock, as well as several other ones.

For the locks part of the group, some of the pin pairs are separated by a third one. The latter is called the master wafer or master spacer. Once three pins are mingled inside the shaft, they can be positioned in two ways to open the lock.

For the change key, the pins might go up for the shear line to reach the position just above the top of the master wafer.

When the master key is used, it might work by raising the pins for the shear line to reach the bottom of the master wafer.

In both scenarios, there is a gap at the shear line, and the key can turn. When the gap is formed at the shear line, it will cause the key to turn in the lock.

For master key designs, the lowest pin must have the same length in each lock part of the group.

However, the master wafer will have different lengths. This will enable the holder of the master key to get access to any lock part of the group. A person with a change key will solely be able to only open their own.

How Does a Master Key System Work

A master key system is simple and sufficient. A single key is designed to work with multiple locks, rather than just one.

This is a commonly used option for businesses looking to transform their outdated security measures and gain control over the number of people with access.

However, it’s not just commercial buyers driving sales of master key systems, domestic shoppers have started turning to this solution, too.

Master Keys vs. Alike Keys

Many people confuse keyed-alike (KA) locks with master key locks. Keyed-like systems are sets of locks that can be opened using the same key.

All locks in the set are clones of one another, and they have the same set of pins and levers. A keyed lock can only be opened by a single key or its copy.

On the other hand, similar master key systems refer to sets of locks that can all be opened by both a master key and a separate key.

Pros of a Master Key System

Installing a master key system has plenty of pros. Here they are to help you decide if it is a good fit for your home.

Master key systems are cost-effective and budget-friendly. Not to mention, it is an efficient security measure, which can eliminate the need for multiple locks or additional security devices.
