Somewhat related: the lock in my apartment is actually based on cryptography too. It uses SHA-1, which is somewhat scary, because it's not considered "safe" anymore. The algorithm was probably chosen because it uses less energy compared to safer ones, as the lock gets the energy from the turning of the key.
