Ive replaced the battery in both key fobs for my vauxhall vectra, one is now working the other isnt!! I did it in the 15 seconds it suggests but it now doesnt work, how do i get it working??
Put the key which is not working in the ignition, turn ignition on (dash lights on, don't start engine), press and hold lock button on key. Doors should lock then unlock. Job done.
