Hi all, I am going to change the keyfob battery for my 307 as I have to get within 5 feet of the car for the remote to work now! I'd better change it before I get locked out! Is there a procedure to resync the keyfob with the car after the battery is replaced, like unlock manually get in the car and press the unlock 5 times then back outside press the lock button? (along with standing on your head, rubbing your tummy and tapping your right foot :-)) Or is it as simple as just chage the battery and it works (not likelely I know but there is a chance). Thanks, Chris
