I'm actually more worried about this[1]. I don't want my key and associated information stored with bank-grade cryptography, I want it deleted after it's cut and sent out. It's easy enough to change a password if you get hacked, it's slightly more difficult to change a credit or debit card but it's more hassle in "changing all the places it's used" than anything else. But changing locks is a huge pain, and not always possible to do depending on what the key is for. I'd far rather take a picture of a key, save it somewhere secure myself, and send it in when I need a copy made. Having both my shipping address and the key to that address stored on a remote server is particularly worrying to me.
