Thanks everyone. Let's hope the saying is true and karma really is a !!
It bugged me how they by passed the central locking and alarm as the van was open and alarm off when I found it and the central locking wouldn't work to lock it. I locked it with the key, left it for an hour then the central locking would work.
Found a couple of odd things today. Our door bell and outside deck light wouldn't work both work on remote conrol basis. Can they really buy a product that can send a signal to turn thing off in the area they're about to rob?!!
