Key Code:

We offer our customers the ability to have all your new locks work with the keys you currently have. This feature will save you time, money and allow for smooth transition in using your newly purchased hardware. All you need to do is enter your current keys Key Code in the box provided on the Product Ordering Page.

If you do not know your current key code here is how you find it:

  • The key code should be stamped on your original keys
  • Your contractor should have this code on file
  • Bring your keys to a local locksmith and they will be able to determine the key code

 

Key Codes depend on the type of cylinder your locks contain. All residential applications will either consist of 5 or 6 numbers. The manufacturers we stock all use the standard in residential applications which is the C Keyway. This just means that all keying regardless of manufacturer can function off of one key. So feel free to mix and match manufacturers as you see fit.
