What is a master key?

A master key provides a whole new level of security for premises of all sorts. Master key systems are key plans where selected keys can open a number of pre-defined doors, with access determined by individual roles or requirements. A master key system gives homes or organisations more control over their safety, and provides convenient yet filtered access to the rooms on your premises. Master key systems can also save you money on key-cutting and replacement costs.

FAQs about our master key systems

How does a master key system work?

Master key systems generally use cylinders with specially-designed pins which can be re-configured to allow different keys to open certain locks. The master key is designed to open all the locks in the system, while each individual key will only be programmed to open a specific lock or group of locks. This allows for greater control and flexibility when it comes to managing access rights for different users.

Why should I use a master key system?

Master key systems offer a high level of convenience and security for properties with multiple users, as they allow each user to have access to only the areas or locks that they are authorised to use. This increased control over access rights can help to ensure that no unauthorised individuals gain access to the property, while still allowing those who are authorised to easily access the areas they need. 

What is a Grand Master Key?

A Grand Master Key (also known as a Grand Change Key) is a specially-designed key that can open all locks in the master key system, including those locked by other change keys and individual keys. This provides an extra layer of security, as it allows only one key holder to have access to all areas of the property. 

How secure are master key systems?

Master key systems provide a very secure locking solution, as they allow for precise control over who has access to which areas of the property. As each individual in the system is assigned their own key, unauthorized access can be strictly limited and closely monitored. Additionally, a Grand Master Key adds an extra layer of security, as it cannot be duplicated and only one person holds the key. 

Are there any drawbacks to using a master key system?

The main drawback to using a master key system is that if the Grand Master Key is lost or stolen, it can be difficult to regain control over access rights. As such, it’s important to ensure that only one person holds the Grand Master Key, and make sure that proper security measures are taken to protect it. Additionally, master key systems can be more expensive than other locking solutions, so it’s important to consider whether the increased security and control over access is worth the added cost. 

Can I install a master key system myself?

Installing a master key system requires special tools and expertise, as each lock must be configured correctly for the system to work properly. Always seek the help of a professional locksmith to ensure that your system is set up correctly.
