Will Sezam24 work in the situation in which some doors are ready for the installation of electronic locks, and the rest I would like to replace only with door handles?
Yes, when it comes to electronic locks, these must be one of the locks supported by Sezam24. You can find their list in one of the previous questions.
However, in the case of ordinary door handles, the guest can check-in at the kiosk and pick up the key at the reception or, for example, take it from the box by the device.
