Place your OV-chipkaart in the slot on the control panel. You will hear a tone informing you it is safe to open the door. Inside the box, follow the instructions on the key machine display. A number will appear that corresponds with the number on the OV-fiets key for your rental bicycle.
Place the bicycle back in any free spot in the box and lock the bicycle. Go to the key locker and follow the instructions on the display. You will be asked if the bicycle is in good condition. If that is not the case, you can report the damage or defects, and the OV-fiets will not be rented out to another person until the damage has been repaired. Place the key pin in a free spot in the key machine and exit the OV-fietsbox.
