I can't unlock my Facelift CDTi Tourer on either of the two fobs but it will unlock on the key but when door is opened alarm goes off as BCU presumably knows to set off alarm, so Battery unhooked and alarm stops, I have locked on key , re- connected battery but alarm still active, then all of a sudden all doors will lock and unlock on fob but alarm still active so off it goes again, I have checked bonnet sensor and it seems to be working, and during all this I can actually start the car!

It was recommended by my MGR mechanic to unplug the BCU and plug back in but all still the same and also all door actuators are working.

It seems that at the moment the car has decided not to recognise either fob to disarm.

This is doing my head in - HELP!

NOW FIXED - Thanks to the helpful advice from Yorkshire GOC.
