Hi. There is no way to bypass the anti theft system. If the theft light is blinking rapidly when you turn key on then yes that is your issue.
So, to understand you, the answer to how to reset the truck's anti-theft device so the engine will start is to take it to the dealer and not to our usual shop? There's nothing wrong with the car but it's decided not to allow us and we will have to pay the dealer to reset it? This isn't sarcasm and no offense meant, but this sounds incredulous to us and we just want to make sure we understand we've hit a brick wall on this.
