hi all, before I start buying can some kind sole tell me if I am on the right track with the latest issues please. Will keep it brief. new heavy duty battery new 120amp alternator battery goes flat after a couple of days poss rf receiver? rebuilt key fob new buttons and batteries re sync ok now progressed to "enter key code" msg which it will not except engine disabled ,alarm light constantly flashing .all the doors will open apart from passenger front which seems to be dead locked, would this be a knackered micro switch? or has anyone got a better idea as to what's going on
