...And don't forget to link with Foursquare account, so we'll know when you're on vacation overseas! Well, I'm obviously kidding, but I don't feel it's wise to share key material just like that. Guess, an encrypted file that's kept near the lock (like QR code kept at friendly neighbor's place or in your own postbox) which is decrypted and shown to a locksmith only when necessity arises would be a better idea. Unless, well, you forget the passphrase (which has to be strong) to decrypt the key. (Yep, they may kept data encrypted, and they probably do, but one has to trust on their word for that.)
