Hi, the infra red key recently stopped operating the central locking system ( though it does work the ignition still ) and so I replaced batteries and still no good. Does any body know how to reset / re- home it if this is necessary..? or could it be another fault - as I'm mechannically unlocking the drivers door now, the electric mirror and window won't operate on that door, and neither do the front interior courtesy lights...?
Could this be a sensor or fuse issue do you think?

I'd be very grateful for any advice.

Regards,
