Disconnect the battery
Remove the fuse if the device is on a dedicated circuit. Otherwise, disconnect power to the device.
Have a Pontiac dealer's mechanic look it over and tell you.
First, disarm the theft deterrent system. Then you can power off and disconnect it.
To disconnect the theft alarm on a 2002 Pontiac Montana, first, ensure that the vehicle is unlocked. Insert the key into the ignition and turn it to the "On" position without starting the engine. Press the "Unlock" button on the key fob, or manually unlock the driver's door using the key. If the alarm continues to sound, disconnect the battery for a few minutes to reset the system.
