If the charger does not unlock from the car when you have completed charging, ensure you have completed all processes required to end the charge on the Level 2 or 3 public charger display. If that does not resolve the issue, most likely, the auto lock connector preferences have been set. Enter the vehicle through the driver’s side door and lock and unlock the car using the controls on the door. The charger should then open.

To reset the preference, use the screen and select Settings > Charging > Connector Lock > Off.
