central locking unlocks itself some point after locking it. i lock the doors using the key fob, but when i return, it won't unlock, to then discover my car is unlocked, i'v tried using both of my key fobs, but it happens with both, Has anyone got any ideas???? i also found the other night, when i parked my car up for the cinema, that on return, my car wouldn't unlock, firsly thinking it had unlocked itself again, but to my suprise it hadn't!! it was locked but my key fob wouln't work, i manually unlocked the drivers door, but this did not unlock the other doors i had to get in, and turn my key in the ignition n then use the internal button to unlock the other doors????? this has confused me even more can anyone help???
