Re: Problem with Key
Yep if it starts, or rather the code light goes out, then there's nothing wrong with the transponder code system and both your keys are being recognised.
The remote alarm/central locking is controlled seperately. In the 155 the receiver is in the rear interior light but I'm not 100% sure if its in the same spot in the 146, actually something rings a bell in my head that its in the front interior light in the 146......
Anyway there is a sequence on this site somewhere which I found and it showed how to re-program the receiver, by entering the code with the small 'secret' button in the mirror with a pin or similar. It worked for me but you need the original 4 digit code that came with the car when new.
