Solved this problem on my 97!
Hey, I had exactly the same problem on my 97 Chrysler Voyager.
Tried everything, by the book, by suggestions from the good people on here. But still could not get it to disable the autolock feature.
Finally found this piece of information. Step 2 below is what I had not been doing.
Step 1. Close all doors.
Step 2. Place ignition key in the OFF position for 20 seconds or more. (this is the step all the other instructions failed to mention)
Step 3. Turn the key to the RUN position and to the OFF position (without cranking the engine). Do this four times. Apparently the "Malfunction" lamp will come on each time when key is in the RUN position - mine did not, however.
Step 4. Press the door lock switch (ie the one on the driver's door that locks all doors) to the lock position.
The programming is now complete - the doors should no longer autolock at 16 mph!
Hope this works for you as it did for me.
