To open your Serea Smartlock, an active NFC antenna on your phone is required. On iPhones, this feature is automatically enabled, but on most Android devices, you’ll need to activate it manually.
To do this:
Open the Settings app on your phone.
Go to Connections or Wireless & Networks (the exact wording may vary depending on your device).
Look for the option labeled NFC and toggle it on to activate your phone’s NFC antenna.
Once NFC is enabled, your phone will be ready to communicate with and unlock your Serea Smartlock.
