In this article, discover all you need to know before integrating the master key system into your property.
What is a Master Key?
A master key is a key that can be used to open different locks. People often believe they have a master key because the key works with different door locks in their house. In reality, the locks in their homes are keyed alike, making it easy for similar keys to open the locks. Typically, a master key overrides every lock in a system, no matter the design. Even though none of the keys available in the system may fit each other, the master key grants access to all locks.
Five Things You Need to Know About a Master Key System Security

Master keys give you access to all doors within a particular system. This means that if the master key falls into the wrong hands, they can easily unlock every door. The good news is that with master key systems, key copying is prevented. All keys under the system are created on a restricted keyway, preventing key copying without the revelation authorization.
3. You have the option of key tracking

Master keys eliminate the need for a massive bunch of keys. Carrying around different keys for different doors in an apartment building or office complex can be exhausting.
In an emergency, master locks can be opened conveniently using a single key. For maintenance purposes, superintendents, managers, and security guards can use a single key to open and close all the building doors.

Can a Locksmith Set-up a Master Key System?
Yes, a locksmith can make a master key. If you need to set up a master key system, you can contact an expert locksmith Toronto to help set it up.
How Much Does a Master Key System Cost?

Some factors that determine how much you will spend on a master key include:
- How many areas require special restrictions/access
- How many copies of keys you need
- The various types of keys you need
- The number of doors in your system
- The complexity and size of your system
Generally, a simple system begins at about $30. Considering the convenience and extra security of a master key system, this is a small price to pay.
Can a Master Key Open Any Lock?
Yes, a master key can open all locks in a system. No, a master key cannot open every similar lock, except the manufacturer builds that feature in.
A modern pin tumbler lock system with the same type of lock throughout can be set up using master pinning. This type of pinning will allow a master key to open any available lock in the system. However, this does not mean that the same master key from building A will open similar locks in building B.
With the warded lock system, you may be able to configure one key to unlock all doors, while individual keys can only unlock one or two select doors. You may find that your master key opens other locks from the same manufacturer, depending on the level of thought put in the designs.
How Do You Tell if a Key is a Master Key?
A master key opens all the locks in a particular system. If you have a key that has been fashioned or designed to grant access to every lock in a system, it is a master key. Master keys should not be mistaken for keys that can open like locks. A true master key will override the system, irrespective of design.
How Do Master Key Systems Work?
There are several keys in a master system, offering different levels of access. They include:
Great Grand Master Key
This master key will grant access to all grand master key systems under it. It will also offer access to the master key systems under the grandmaster keys and the change keys.
Grand Master Key
A grandmaster key grants access to multiple master key systems. This master key opens all the master systems under it, and subsequently, the change keys under those systems.
This is the main component that transforms a basic lock into a master keyed lock. Without this key, individual locks have their keys. Some master key systems consider this the highest-ranking key.
The change key is also known as a sub-master key. This key will only open one lock and replica locks. A master key and other keys above that rank can also be used in opening the lock that the change key opens.
Components of a Master Key
You will find skinny cylinders that move up and down. Usually, there are two pins, one below the line in the lock’s center and one above.
The shear line is the straight line that goes through the center of the lock. The shear line creates the space needed for the lock to turn when the pins line up.
At the key’s jagged edge, you will notice notches designed to match the pins contained in the cylinder. What differentiates a master key from other keys is that their locks have a third pin. This third pin is called a master wafer and can only be unlocked by a master key.
Usually, master key systems operate off a simple pin tumbler lock. A pin stack made up of a key pin and driver pin must be elevated to open this type of lock. This elevation will allow the two pins to rest opposite the shear line. When a key is inserted, it lifts key pins within a lock. These key pins are in varying sizes, but the driver pins are usually a universal size.
Therefore, to lift the key pins to the required height, the key needs to have the right set of grooves. All you need to convert a standard pin tumbler to a master key system is a master pin. More commonly known as s master wafer, this is a small hockey pick shaped pin placed between a key and driver pin.
Once the master wafer is in place, the pin stack will branch into two shear lines. One of the shear lines will hold a pin stack, with its master wafer located above it below the line.
