Master keyed locks (also called a master keyed system or suite) are a number of locks that operate with their own individual keys, but can all be operated with a single master key. We combine our master key system with our restricted profile to give a restricted master key system. Property owners / management have complete control over the issuing of keys and additional keys. Also owners / management have the convenience of operating all the locks on their properties with a single key. No more trying to keep track of which key is for where or carrying around bunches of keys like a prison guard

Here is an example of how a Cuddihy Window & Door Services restricted master keyed system is advantageous in a managed properties setting.

  • Property 1: Front door and back door
  • Property 2: Front door, back door and garage door
  • Property 3. Front door, garage door and a set of French doors.
  • Property 1 – The tenants key will open both doors at this property only
  • Property 2 – The tenants key will open all three doors at this property only
  • Property 3 – The tenants key will open all four doors at this property only.
The landlord / owner’s master key will open every lock at all three properties.
As the master keyed suite is also restricted, a tenant cannot get extra / spare keys cut at any other locksmith or key cutting service. Spare keys can only be cut by Cuddihy Window and Door Services at the request of the owner.
The highest level of convenience, security and peace of mind all together in one package.
