http://www.explorerforum.com/forums//showthread.php?t=195398 Has a lot of info on keyless entry, and says to enter your code and press hold 7/8, press release 3/4 then release 7/8.
That being said, I have been unsuccessful doing it on my 95. We have some different things from others, like to program a remote, we only cycle the key 5 times instead of 8, so I am thinking a 95 is programmed differently.
And it is. This is from the manual for a 96:
You can also deactivate or reactivate the Autolock feature by
this method:
1. Make sure the anti-theft system is not armed or triggered,
ignition is off, and all doors and liftgate window are closed.
2. Turn the ignition key from OFF to RUN.
3. Press the door power unlock button 3 times.
4. Turn the ignition key from RUN to OFF.
5. Press the door power unlock button 3 times.
6. Turn the ignition key back to RUN within 30 seconds of step
2.
7. The horn should chirp once. If not, wait 30 seconds and
repeat steps 1 through 6.
8. Press the door power unlock button.
9. Press the door power lock button.
10. The horn will chirp once if the Autolock feature was
deactivated, twice (one short chirp followed by a long chirp)
if the Autolock feature was activated.
11. Turn the ignition OFF.
12. The horn will chirp once to confirm that you activated or
deactivated the Autolock feature.
I will test this once the sun comes up!
