Sliding Patio Door question

Yes, those holes at the lower corners are the access holes for the roller assy to adjust the panel position. Normally a #2 Phillips is the required tool, a healthy dose of WD-40 or other in each hole won't hurt. The sliding panel should be able to be lifted up, then the bottom rotated inward to remove it. Before you attempt to pull it out, open the door and look up at the top of the frame(the head) and see if there are any filler pieces or spacers etc above where the venting panel sits when it's closed. These are at times used as an "anti-lift" device to prevent nefarious souls from just lifting the panel up to remove it and gain access thru a locked door. Sometimes you remove those to pull the panel, other just slide the door over to the "open" position to clear them then rotate inward.

If the bottom of the panel hits something, it's probably the rollers. If so, stick it back on the track and adjust the rollers so that the panel moves down(which sucks up the rollers) and you should be able to get it clear then, but you'll need to adjust those rollers again once you stick it back in, otherwise your operation force will suck.
