To unlock a 1991 Pontiac Bonneville radio, you typically need the security code that was provided with the vehicle or the radio's manual. If you don't have the code, you can often retrieve it by contacting a Pontiac dealership and providing them with your Vehicle Identification Number (VIN) and radio serial number. Some users may also consider removing the radio to find the serial number, which can be used to obtain the unlock code.
on a 93 Pontiac Bonneville you would remove the passenger side front tire. there may be a plastic cover that just pulls off. look to your left,back and up a little bit you should see the wires that connect to your cam sensor. theres your cam sensor. 91 Bonneville is probably the same.
