I've seen few too but all of them were Rover 75 keys even though they were advertised as D2 keys and we all know what's the difference... here's the risk: if the car stood unlocked more than 15 seconds and the R 75 fob fails to give unlock command(let's say due to faulty microswitch which is common) then the engine will be unstartable due to the passive immobiliser as the R 75 fob doesnt have the "hardware" to work with the passive remobilisation exciter coil...i've seen this with my own eyes not onceKeys can be easily sourced on the internet, I usually pay about £10 to £15 for mine.
