I hope someone will help me with a big problem!!

I have a 1999 3.3i v6 Grand Voyager / T&C in the UK it has been running fine up till yesterday!!! I went to it in the morning and unlocked the car with the key fob, then tried to start it and the "Alarm Set" starts flashing and then beeps 16times and then stays on permenantly and the car wont start.

I only have the Grey key and fob, the wife lost the other set!!

I went online and found the suggestion of the plug on the heater control panel pin 21 and that is fine no melting or anything but tested it and still the same.

Does anyone have any ideas? I need to get the car working ASAP!!! as we have a disabled child and need the car for mobility for her.


Thanks for any help in advance!!!!
