I hooked up a Bulldog Deluxe500 to my wifes '02 Chev. Trailblazer. It worked fine until I tried to change the programing to "check voltage" to confirm run on ignition. Now the key chain beeps 3 times when I push start button. The system will not reset to default settings, nor will it reprogram the start up buttons - keychain beeps/alarms 10 times when a press the valet switch the required 3, 8 or 12 times. HELP!
