A company called KeyMe has introduced an ingenious app which allows you to scan digital copies of your house keys.

The iPhone app stores a copy of your keys specifications, including its type and the height of and distance between the key’s teeth. So, rather than waiting for a locksmith to replace your locks, you can take your phone straight to a keycutter and have them cut a new key from the app’s digital copy.

KeyMe also have special kiosks situated around New York that you can take your iPhone to and have a new key produced within 30 seconds.

At present the app’s use is restricted to certain key types, but KeyMe is a promising feature for those who find themselves having to replace lots keys on a regular basis.
