when I try to unlock the doors with the fob it wont unlock and the power window and door lock buttons stopped working
what makes the key fob not unlock the doors and the power windows not work on 2002 Pontiac Bonneville
This could be an issue with fuses. Your best bet is to go to your local auto parts store, but a box of all different kinds of fuses, and replace the ones that indicate the problem areas for your car in the manual. If this doesn't work, it could be a wiring harness. Also, replace the battery in your FOB.
