My wife finally got her Citibike key in the mail yesterday. It appears to be used and reassigned. The bar code is quite marred. We will see if it works. She had to go online and register the number printed on the key, but one of the digits was rubbed out! She tried replacing the missing digit with 0, no good, then she tried 1, and that worked, and it brought up her personal information, so 1 was the right guess. Not impressive, rather rinky-dink. But if it works, all will be forgiven.
