Thanks Dippypud, not in the least electrically competent so don't really know where to find the sensors apart from possibly ? the bonnet one, so will try that this morning,also I've been told that if I disconnect the sounder that the hazards will start flashing and wont stop ??

Thank you for that Mark, yes it did unlock with the key fob beforehand ,the doors aren't open but as soon as I reconnect the battery it kicks off.

I have been doing some welding on the above so disconnected the battery but now that I've come to reconnect it every time I do the alarm kicks off and wont stop, I've followed all the procedure's in the handbook all to no avail it still goes off, thought of pulling the wire out completely but...
