The procedure will replace the previously programmed key fob with the key fob requiring programming.
(Follow Instructions, if it don’t work repeat entire procedure)
All desired key fobs must be present.
When the first key fob is programmed, the module will erase the rest of the slots.
The module will fill slots until [Done] or [Exit] is selected.
Note: Only select [Start] once. If the procedure is started again, the control module will start over.
