Are there PIN code locks where the owner can remotely change or disable specific PIN codes? That is, rotate to a new code when each guest’s stay has ended (either automatically or manually by the host), and of course retire/erase the prior guest PIN code.
I suppose the next level would be some ability to remotely monitor and track the use of each guest’s access. So you could see when a new guest arrives for the first time, as an example.
Of course, any lock with any form of remote control must be viewed from the angle of potential ‘internet’ hacking or other unwanted lock behavior.
