Recently picked up a 05 EGC with an dealership installed alarm system. What's the secret with programming a code to disarm the system? I tried following the manual numerous times and no luck. Do you have the system on, steps to disarm the system, etc. anyone with help it's well appreciated.

Thanks

 

If you are talking about using the turn signal switches to enter disarm code, check the manual where it explains how to count the key flashes to determine what code (if any) is already programmed. From that point you can "add to" what is already there. Meaning if a 5 is entered 2 additional turn signal presses will change it to a 7.
