Should cost you $20 or so.
Also, you can disable the auto-unlock feature, see that post above. 97/98 Explorers are pretty much the same, I would say it would be relevant for a 98.
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.
