hi, my problem started a month ago came to open car with remote, no go, used key in lock to open it,dead battery jump started no problem but now has no remote locking even the button on dash does nothing but locks all doors manually with key in door lock also all interior lights are not working, tried key programme still no go. Sent car to auto electrics people and they have messed with it and now its got no volume on anything still nothing works they reckon bcm
