hello fellow c4 drivers ! ,   Can anyone "please" help with this matter ? . Two weeks ago A A , fitted new battery to my car , since the new battery i have nothing but trouble with key fob ie , car locking by itself , starts then  wont start , ect . AA are refusing to admit responsibility as they said when their mechanic left me car was going ,i`am beyond  all hope on that matter , is it true that the mechanic has "spiked" my key code , inturn  all information to keyfob circuit boared is not recognising information and that the only way to solve this will be to get to a citroen dealer and get keys "re-mapped"  ? . I`am losing the will to live with this now !! :).    cheers paul.
