When I press a button on the hatch to close the hatch, it closes pretty slow... Then I have to verify that it is closed then lock on my remote control. I would like to auto lock when the hatch is closed. Is it possible? I decided to press the button for long time (2-3 seconds) then the light blinks then hatch closes, but it does not lock or do anything special. Is it doing something? Does it suppose to auto lock but mine is broken?
