How do you disable the factory alarm on a Chrysler PT Cruiser?

Answer 1

This is where it gets a little tricky. Chrysler (especially) has been known to incorporate the anti-theft device in the pcm, assuming it IS a factory alarm. If it was dealer installed, then you're gonna have to get a schematic for the ignition system, hunt down the wires that have been spliced into, and bypass the anti-theft module. Again, if it is indeed a factory-installed module, there may be a problem. Removing bits that the pcm has gotten used to hurts its feelings, and makes it go on strike.

actually if u dont want your alarm to go off when u lock the doors u need to lock all the doors from the inside instead of the driver side lock it from the outside then unlock the doors and tell me if that works
