If you have guests visiting or if you are an Airbnb host, sometimes, they may encounter difficulty in unlocking the door, especially if you have the SDL-H1 or SDL-H2 lock models installed. This may likely be due to the privacy switch located on the interior panel being inadvertently activated. When the privacy switch is turned on, it restricts access and only allows the Bluetooth Administrator to unlock the door from outside. This can potentially cause problems for your guests if they lock themselves out.

To prevent such a situation, it is recommended that you disable the privacy switch feature. You can accomplish this easily through the TTLock app.
By doing this, you ensure your guests can access the premises conveniently without needing you to intervene each time they wish to unlock the door.

To know how you can disable this feature, refer to this article titled, 'How to Disable the Privacy Mode in the TTLock App'. It provides step-by-step instructions for you to follow.
