I think you're going to have to expand on that... how to lock doors when top is up? Er press lock?
If you mean auto lock, it only does that if you unlock the car but don't enter it.. after a short time, it relocks thinking you hit the button by accident. I've never noted whether top up or down make a difference to this tho.
