How Do Restricted Keys Work?

Suresafe Locksmiths • September 9, 2022

Provide your residence or commercial space with the ultimate security by installing a restricted key system. These systems allow keys to only be duplicated by yourself or someone you've authorised, and for the locksmith who produced the original design to be the only one who can cut new keys. Interested in learning more about this great security feature, how it works and what it might offer? Read on to learn more.

How do restricted keys work?

Every restricted key is its own unique entity and carries an identification number controlled by its owner. This means no other locksmith is able to cut the restricted key that a registered locksmith has authorised and holds - doing so is even illegal. If there's a problem with a restricted lock, it can be serviced and repaired as long as the work doesn't interfere with system functioning.


If the owner of a restricted key wants to make a copy, they can either make the new key themselves or provide written permission for another person to collect the keys for them. 


The secret to restricted key systems lies in their complex blank network and uncommon broaching, or non-standard profile. This design makes it impossible for anyone other than the original locksmith to duplicate the key. Each key comes with an individual identification number and is classified under a unique system number for the greatest control and security.

Restricted key system benefits

There are fantastic benefits to a restricted key system. These include:

  • Secure locks: Your restricted keys are unique and only able to be duplicated by those you've authorised. This means you won't need to worry about the unauthorised duplication that might occur when standard keys are lost or stolen.
  • Greater access: You can customise a restricted key system to allow different levels of access to different users, and to include a master key that's universal. This flexibility offers the reassurance that you'll know exactly who can enter your home or business at any time.
  • Accuracy: Your locksmith will keep a clear record of your restricted key system. This means you can easily keep track of copies and know when they were cut and who authorised duplication.
  • Durability: It's very hard to pick a restricted lock or use a different key to open it. This is due to a restricted key's unique design, which includes more intricate features than a regular key.
