Is there a way to disable the security system? My truck turns over but won't start. The red key warning light is flashing on the dash. According to the manual the computer is not accepting the key code, so the security system is locked on. The mechanic I spoke with said the key has to be coded at the dealership with the truck. I Have to have the truck towed to the dealership then pay them $100? This is ridiculous. I'd rather not have a security system.
