Fantastic, thank you for all that - makes perfect sense.. I've just ordered the same programmer, once it makes it's way from China I'll get busy.

I'll bother you again once I have that data dump done. To confirm, I have the green label CODE box. I presume it has at least 2 key codes stored, but if I end up with a clone of the one I have, or 'the other one' that's all good, as long as I have a spare.

Presumably the transponder burner won't clone existing keys for the obvious reasons!! Shame though, it would make life simple wouldn't it.
