No. Blade blanks are similar to traditional key blanks in that they do not work until they are duplicated to fit your particular lock. Keyport ships you the Blade blanks, which you take to a locksmith or key cutter along with your original set to duplicate.
The only instance where we may be sending you a precut or "live" Blade is when you have a custom key for which we cannot obtain a corresponding blank. In that instance, you may need to send in a copy of your original key to be custom modified. We would be sending back the same key transformed into a working Blade. For the return address/shipping address, we do not recommend including any addresses linked to the keys you are sending. Instead use a trusted friend's address, work address, etc.
