ive recently switched to an e53 X5 from an A4 and really really dislike the key.
an odd thing to hate i know......!
i was wondering if there was a way to possibly replace it with an audi flip key like this one?

has anyone got any experience with this and how hard it might be?
also where in london can i get the key cut? is it only the stealership that cuts keys?
thanks for any advice info!
