Hi guys, i need help, i went shopping yesterday and came back to the car to find the central locking would not open and had to use the key, the alarm did not activate either as it usually does.
The car was just serviced two weeks ago and new batts replaced in remotes.
I have 2 keys and neither work on opening the doors but do work opening and closing the windows, tried adding a piece of paper on the back of the battery to give stronger connection with no joy and also re-sync the remotes and the fuses are okay too. can anyone help
