I purchased a used Smart for two 2015. When I bought it the guy told me it needed a new gear selector with the ignition in it. I can't remember what he called it now. Anyway, I bought one used for 150 dollars and installed it. It came with a key and didn't work. He had the ignition bypassed with a trigger button to start it. It will start with the trigger but will not move. I jacked up the car while started and the rear tires will begin to move but its not strong enough to move the car while on the ground. Also, if you step on the accelerator peddle it doesn't do anything. On the Dash It doesn't show P R N D at all but the wrench flashes. I need help Please!!!
