I somehow lost the 1-chirp lock and 2-chirp unlock functions for my alarm. I know I caused this problem myself -probably by holding down more than one transmitter button too long. I have tried to follow the manual for restoring the chirps but have not been successful. All other alarm functions seem to be working. Can someone please give me the "Alarms for Dummies" step by step - top to bottom directions for restoring the missing chirps?
