You can unlock a bike only through the Donkey Owner application.
- Login to the Owner app and make sure you are into the fleet view (Select 'Fleet' at the bottom left corner of the screen).
- Press bike name (of the bike you would like to unlock) from the bike list.
- Make sure you are close to the bike/lock.
- Press 'Unlock button'
The ap will then connect to the lock. A new page will open and a loading bar will show you the progress of the unlock operation. Make sure you hold the smartphone as close as possible to the lock, especially if there are more locks in the surrounding area.
