If you receive the message "No key assigned" during registration, it means that no key has been assigned to your phone number. Keys are assigned on the day of check-in only if the booking is paid in full.
If you are unable to register your phone number or not receiving any SMS, please ensure that you have internet access on your phone and that you are able to receive SMS messages. If the problem persists, please contact our customer support team.
If the door blinks yellow when you try to open it, it means that there is a problem with the connection between your phone and the lock. Ensure that your Bluetooth is enabled and that your phone software is up to date.
If the door blinks red 3 times in a row, it means that the lock's battery is empty. Please contact our customer support immediately.
To ensure privacy and prevent room service from entering your accommodation while you're inside, simply locate the button at the bottom of the door knob. By pressing this button, you can activate a lock mechanism that effectively prevents anyone (except you) from accessing your accommodation from the outside. The lock automatically disengages when you open the door by pulling the handle.
If you want to give door access to an additional person please : - Install the JustIn Mobile App - Provide us with the phone number by mail on [booking@coucounco.ch](mailto:booking@coucounco.ch).
