Explanation:

Based on the information provided within the question it can be said that the cryptography concept that is being illustrated in this example is called Symmetric key sharing. This is a cyrptography concept in which the sender and receiver of a message share a single common key that is used in order to be able to decrypt this message. This private key can be shared with any trusted individuals that need to be able to decrypt the message. Such as any trusted individual that need the key to the front door in question.
