I have an extra W222 key (S560).

If you're interested at c $700, obo PM me.

 

If it's already been programmed to a car, it's worthless.

 

For OP and potential buyers: If this is a used key, note that it can not be “reprogrammed.” No matter what anyone tells you.

if it is a brand new key, it will require a dealer visit and their associated fees. Don’t be surprised if they refuse to accept a key that you bring to the table.

 

Ah, so…

Thank you.

What about as a curio?

There shouldn’t be very many in used jewelry shoppes.
