Does the lock fit into any doors?

The lock is installed in place of a standard handle and fits into all modern, standard European doors.

Does the lock have to be on-line?

The lock must be within Wi-Fi network because it synchronizes data with the server at a certain time. The codes are stored inside the lock, so temporary lack of Internet does not cause any problems in the operating system.

Does the lock work outside?

Generally yes, but you have to avoid exposure to rainfall and strong sunlight.

Do I have to pay any fees for the system that supports the lock?

Yes, there is a subscription fee. The BookingLock is associated with locks and a part of the constantly working and improved software on the server. The subscription is necessary to maintain services at the highest level.
