Can I reprogram auto door lock feature-97 Explorer

Is there a way to re-program the automatic door lock feature on a 1997 Explorer so the door locks open when the key is turned off. It is really frustrating when you have to push the "unlock" button every time you get out of the vehicle to get items out of the back seat. The local Ford dealer says it can't be done (or they don't know how to do it).

To active/deactivate autolock/relock feature:
1.Turn ignition from OFF to ON/ACC.
2.Press power door UNLOCK,three times.
3.Turn ignition from ON/ACC to OFF.
4.Press power door UNLOCK three times.
5.Turn ignition from OFF to ON/ACC.
A horn chirp indicates the activate/deactivate feature mode is entered.
6.Press power door UNLOCK one time.
7.Press power door LOCK to switch between Autolock/Relock.
The user will hear a horn chirp followed by either a:
Long honk--autolock/relock activated.
No honk--autolock/relock deactivated.
After leaving the activate / deactivate mode,if autolock/relock has been
changed,there will be a horn chirp.

I assume you leave the activate/deactivate mode (after step 7, the chirp & the honk/no honk) by turning the ignition to OFF?
