The Pontiac Montana does not come with a factory installed amp in the sound system. The wiring goes directly from the radio to the speakers.
It will probably have to go to the dealer and have the system repaired & then they have to reprogram the security system
How to disengage Pontiac Montana 2002 anti-theft system
If you have the "PassLock" Security system on your vehicle, you MUST take it to the dealer to have the ignition changed out. The will have to reprogram the security system to match. If they don't your security may stay engaged which will cut of the fuel.
The 2003 Pontiac Grand Prix does come with a factory security system installed. If your security system is enabled it should have a "security" light that flashes when the key is turned on.
You can do it with a scanner. Usually when the security light is flashing it means there is a problem with the passlock system. Dealer item and about $500.00-$700.00 to replace parts & reprogram.
you will need to call a pontiac dealer and get an activation code, because of the anti-theift system.
