We sell replacement lock cores for a nominal charge. If you choose to ship your old cores back to us, and we'll reimburse you the same amount you paid us for the new ones.
Why change keying?
You are moving an alarm from one key code group to another.
What you need
If you are switching to a new key code you've never had before, you will also need to order new operating keys.
Cores can only be changed when the alarm is unlocked. Changing a lock core is not a solution if you've lost your alarm key
