Systems and methods for unlocking a digital lock. A system may include a master key and a nested key. The master key may be configured to transmit authorization data to the digital lock or the nested key. The nested key may be configured to unlock the digital lock upon the digital lock or the nested key receiving the authorization data. The nested key may be configured to transmit the authorization data to the digital lock to unlock the digital lock if the master key is configured to transmit the authorization data to the nested key. Alternatively, the nested key may be configured to transmit key data to the digital lock to unlock the digital lock if the master key is configured to transmit the authorization data to the digital lock.
