my key's logo is worn too, i'm going to live with it for the time being, however my plan is to get a new one from flea bay.
take my worn key apart (as if you were going to change battery)
put back together using the original half and the new half with logo on
this way i'll only need to get the blade cut as the half with the battery in contains all the electronics that would need to be programmed.
thats the plan, if that wont work then let me know.
