It should be a thing of beauty.
A client of mine wanted me to design carbon fibre covers what would slip over the old fob when me got his previous Martin but was low down on the list so it never happened.
Quite happy with my 4200 Classico key!
....stick it in the hole and turn it. Job done.
Unless you are in the habit of wearing it on your belt or leaving it on the table in wine bars????????????????????????????
Can't see a problem with the key myself.
They both came a bit scuffed and bashed! One is now resplendent with a shiny new fob, the other is still a more sorrowful looking sight.
