Use the Bring & T Update App to bring your digital key to the latest software version.

  
Step-by-Step Instructions:

    2. Tap "Update digital key" at the bottom of the screen.
  

  

    3. Select your digital key from the list (e.g., BR_xxxxxxxx).
  

  

    4. If your key does not appear:
    

      
Tap [Search again] to refresh the list.
    
  

  

    5. The app will display the current version and any available updates.
  

  

    6. Confirm "Your device is correct". The key’s LED will blink purple for 10 seconds.
  

  

    7. During this time:
    

      
Press the digital key’s button briefly (0.5 seconds).
    
  

  

    8. When the update is complete, the LED will turn solid blue.
  

  

    9. Tap "Close" to exit the application.
  

  

    Important Notes:
    

      
Keep your device within close proximity (under 1 meter) during the update.
      
Update time: 2–3 minutes. Do not interrupt the process.
      
Ensure your device has at least 20% battery before starting.
      
If an error occurs, restart the app and try again.
      
Only registered digital keys can receive software updates.

✅ Key Improvements:

• Clear visual hierarchy with numbered steps and consistent styling.
• Mobile-friendly design with responsive padding and font sizing.
• Better accessibility with semantic HTML and proper contrast.
• User guidance enhanced with icons and visual cues (via CSS).
• Interactive "Update Complete" button (for demonstration — can be replaced with actual app logic).

💡 Pro Tip: If this is part of a real app or website, ensure the "Close" and "Update" buttons are tied to actual app functions (e.g., closing the screen or triggering a background update process).
