How Do I Disarm ADT Chime Without Code?

In the event that you are the owner of the ADT system and your user code is not functioning properly or you have forgotten it, the key fob may disable the ADT alarm system without the need for the code. If you have the key fob on you, all you have to do is click the "disarm" button, which looks like a shield with a slash through it, and your security system will be deactivated; no other procedures are required.
