Hello Dave, I wonder whether it would be possible to program the keys using the Autologic procedure for Landrover, where you can use the number printed on the inside of the plip? It may be worth trying(if you can borrow someones Autologic or get someone near you to try,that is) as the Rover plips program ok to Landrover, or have I mis-understood your post & you have the bar codes, but just didn't get the horn sounding? Hope this helps, Regards,Andrew
