Thanks for the info, Dave. This happened to my car yesterday (2yr old Plus 4). We were just on our way to a meet, so didn't have time to investigate and had to take the tin-top.
This morning I held the chip closer to the barrel (remembering the 20 second rule), and hey-presto the immobiliser dis-armed and the engine fired up.
Now to sort out a permanent fix .............
