Techniques are generally described for a lock system. An example lock system includes a lock with a lock module that controls a lock mechanism. The lock is configured to transmit optical signals to a key. The key reflects the optical signals back to the lock. The key is configured to encode the optical signals with a combination. The lock module is configured to determine whether the combination is valid. The lock module actuates the locking mechanism when the key is determined to be valid. |
