What you might be experiencing is:
* Door Lock Timer: The Explorer might have a timer that automatically locks the doors after a certain amount of time (e.g., 10-30 seconds) after the ignition is turned off and the driver's door is opened. This is a *feature*, not a malfunction, and it cannot be fully disabled without modification.
* Alarm System: If your Explorer has a factory or aftermarket alarm system, that system might be responsible for locking the doors. Disabling or removing the alarm system might indirectly stop this behavior (but this is risky without proper understanding of your vehicle's electrical system).
* Faulty Door Lock Actuator or Switch: A malfunctioning door lock actuator or switch could be causing erratic locking behavior, misinterpreting signals, or causing the doors to lock unintentionally.
Therefore, you can't simply "disable auto-lock." If you're experiencing unwanted automatic locking, you should:
1. Consult your owner's manual: See if it mentions any adjustable parameters related to the door locks' timing or behavior. (It likely won't offer a "disable" option, but may have some setting adjustments).
2. Check for aftermarket alarm system settings: If applicable, review your alarm system's manual to see if you can adjust the locking behavior or potentially disable the auto-lock feature from within the alarm's settings.
3. Have it professionally inspected: A mechanic can diagnose if there's a problem with the door lock system itself (faulty actuator, wiring, etc.). This is the best option to pinpoint the cause of the unwanted automatic locking.
Trying to bypass the system yourself without proper electrical knowledge can damage your car's electrical system, so seeking professional help is the safest and most effective way to address this.
