Changed battery. When I disconnected the positive the Alarm went off but it was a very muffled and quiet sound. Put battery in. The car started fine with out having to enter the pin. Seems strange but I've driven it to get fuel and to work and not once has it needed a pin to start. The brant pin pad doesn't even light up except for the number 1. Even when I lock it the immobilizer led flashes but the pin pad does not. Unlock the car, get in and it starts with no code.
Did any one know why? Is this because it needs to be reset or possibly it's stuffed?
