turn it on, wait until it says CHECK, then hold the TA button and the button to the left of it then press hard upwards so the face plate moves. works with mine every time, did it completely by mistake the first time coz i lost the code but its been working like that for months. Or you can go to a fiat dealer and they'll reset the code for you but that would cost a bit, probaby not much.
