ABSTRACT:
A key fob with a housing into which a deadbolt key is mounted such that the shank protrudes therefrom, enabling a user to turn the housing and cause the key to lock or unlock the door. Within the keyfob are a pair of switches or other sensing means configured to close on either the turning of the housing in a first (clockwise) direction or a second (counterclockwise) direction. Based on the direction the housing is turned, either a first coded signal or a second coded signal is transmitted to a control panel. The control panel will then either arm or disarm the security system based on how it has been programmed during installation. This enables the user to easily arm the system when the door is being locked and disarm the system when the door is being unlocked without requiring a separate action on the part of the user.
