• providing an electrically actuable mobile lock together with an activation means that comprises a virtual key associated with the lock;
• performing an interaction with a first mobile end device and the activation means;
• transferring the virtual key to the first mobile end device and storing the virtual key in the first mobile end device in response to performing the interaction with the first mobile end device and the activation means;
• establishing encrypted data communication between the first mobile end device and the lock while using the virtual key;
• and
• coupling the first mobile end device to the lock and thereby authorizing the first mobile end device to actuate the lock;
• granting administration rights to the first mobile end device;
• performing the interaction with a third mobile end device and the activation means, subsequent to performing the interaction with the first mobile end device and the activation means;
• and
• in response to performing the interaction with the third mobile end device and the activation means, granting administration rights to the third mobile end device and at least one of:
• removing the administration rights granted to the first mobile end device;
• and
