(Pro-E controller) So, I disarmed my alarm. Why does my parking lights flash and I hear a constant clicking sound coming from my receiver when I turn my key?

If you have a sensor installed that detects when your door is open with the “Door-Open Warning” on, it will be alerted if you power the ignition (turn ACC on) while the door is open. To disengage, turn the ignition off and press “Unlock” on your remote.
