Try this:

• Instead of just PIN + Enter, try PIN + Enter and then Enter again

• Or try PIN + "Stay" or "Lock" if your keypad has those buttons

If your model used to close and now doesn't: The safety sensors (photo-eyes) might be misaligned or dirty. Check that nothing is blocking the sensors near the floor on both sides of the door.
