I had this happen to me last year in my 97. Heat and WD finally got it unstuck.
Here is my current thinking on the issue. grease solidifies in the door latch mech.
eventually when its really cold and the grease is really thick, it will jam.
WD40 is kind of a band-aid. WD and a heatgun might get you back on line.
What i would do now is try to clear the old grease out of the latch. The latch is a royal pain
to get out. Next time it happens to me, i an first going to get spray starting fluid and squirt the
hell into the latch and work it back and forth. Starting fluid is a great degreasser. Put gloves on and don't smoke..
What i did rather than close the door was to use the handle of a socket ratchet or such to work the lock claws
on the door manually rather than open and shut the door (takes the place of the door striker plate).
then when you get it unstuck (maybe with some heat latter after the starting fluid has evaporated),
then spray in the lithium grease. Its all about getting the chunks of old grease out of the inside of the lock
mech and getting some fresh in it.
