What points do I have to remember about the 'Lock' function when I change my smartphone?

Install the eBike Connect app on your new smartphone
Log in using your existing account
Connect your smartphone to your on-board computer via Bluetooth. The message "Lock function activated No motor support until lock function has been deactivated" appears. Your account is the key to the 'Lock' function, so you can confirm the message with "OK".
The 'Lock' function will then be set up again automatically. The app indicates when the Lock function is activated
