Keys again

Just been to view a car with The Silver Fox and everything seemed fine apart from when I went to test the keys. The red key starts the car no problem but the silver/blue one and blue key do not. The cars had a replacement engine (don't tell Carlt, no oil ) about 30k ago. So have both my cars but all keys still work.

Any ideas?

Could try the coding sequence on the red key thread

Hi Mike, and thanks again for your help.

I have put a post in the Technical thread about this. After trying the coding sequence the blue key now works, however the silver one is proving more of a challenge!

Not to worry though, 2 keys is enough for me.
