My battery was dying on my keyfob so I changed it. Now it doesn't work at all. I have a spare key that still works fine remote locking etc. The key that doesn't work does flash. I can manually lock/unlock/start the car with it too.
I've searched everywhere and tried serveral methods of re programming my non working key. Anyone got a sure fire method?
