Oh my God! You are my hero! I borrowed my son's car today (usually not a thing he lets Mum do!) and of course it had to go berserk on me. The flipping alarm kept going off every time I opened the door. The fob wouldn't work and the ear piercing scream was doing my head in. I searched and found this reply. Followed your instructions and voila! Problem sorted and Mummy's little soldier will never know his Mother almost drove his pride and joy into a flipping wall!
Thank you so much.
