Hi Shaun I got the toad immobiliser which went well for four years or so, then one day when out and about I couldn't start the bloody car. Just about pulled the dash apart looking for loose wires etc. Got towed home. Tried the spare fob and started immediately !!!! So down to one working fob. If that were to fail the car would be undrivable! Aaaarrrggghhh . New fob ex Morgan costs GBP150 !! So if you get one make sure you get the immobilisers immobiliser jump connector which means you can at least keep mobile. Due to the isolation of the colonies I had to concoct one for myself. Which was quite simples when I finally found the right connector. None in NZ so had to get from USA. Total cost. GBP10 !,
