1- Open the SwitchBot App and see if the Keypad Disable option is still on. If it is, we need to turn it off.
2- If we cannot find the Keypad on the SwitchBot App, it might be deleted when the Keypad is under the status of being disabled. In this case, please try to re-add the Keypad.
3- If the above solutions are not working, please try to replace the battery and re-add the Keypad.
