Friday - Tail gate and driver's door opened ok. 3 passenger doors failed to open from inside or out. Used fob and inserted and manually turned key in driver door. Still no joy. Changed fob battery. Disconnected battery for one hour - reconnected - still no joy. Saturday - tried locks and fob repeatedly then suddenly the near side rear door could be opened !! Sunday morning - all the doors could be opened !! Sprayed WD40 in every hole I could find. Sunday night - the 3 passenger doors couldn't be opened again. Monday morning - all the doors opened - and now I've left the car unlocked. Any ideas re: potential causes would be gratefully received. Thanks Alan
