I have three keys for my lovely......two work fine and do all functions.... One however, works with the exception of energizing the starter motor.. All the bells and whistles light up and work with third key. Just the starter does not energize?????
Any clues appreciated......

 

I'm going to guess that your mystery car is later than 1997 because from 1998 onward, the cars were fitted with a KTM that needs to have the keys configured to the car.

The key could also be a key that was cut correctly but lacks the transponder (built into the key).

Might need to find someone with the correct computer to configure the keys to the car?????
