Lock is non-responsive, even after replacing the battery. Schlague electronic door lock. Will not unlock when using the correct code. Seems totally dead with no power.

If the driver door lock on your 2002 Ford Explorer is not working even after replacing the actuator, there could be a few other possible causes for this issue. Here are some things you can check:

1. Wiring and connections: Check the wiring and connections leading to the actuator to make sure they are in good condition and properly connected. A loose or damaged wire can prevent the actuator from working correctly.
2. Door latch assembly: The door latch assembly is responsible for locking and unlocking the door. If it is damaged or worn out, it can prevent the actuator from working properly. Check the latch assembly for any signs of damage or wear, and replace it if necessary.
3. Door lock cylinder: The door lock cylinder is the part of the lock mechanism that the key inserts into. If it is damaged or worn out, it can prevent the lock from working properly. Check the lock cylinder for any signs of damage or wear, and replace it if necessary.
4. Central locking system: The central locking system is responsible for controlling all of the door locks in the vehicle. If there is a problem with the central locking system, it can prevent the driver door lock from working properly. Check the system for any error codes, and repair or replace any faulty components as needed.

Do you know anything about automotive electronic's , control module's etc.... work including the truck.???? trunk ? Electronic control module ( DDM ) driver door module control's lock's an power windows . Do you have a professional or factory scanner to test for DTC'S - diagnostic trouble code's ? Do you know what diagnostic pin point testing procedures are ?
Power Locks
The power lock/unlock feature requests all of the vehicle doors to lock or unlock upon a request from the door lock control switch, the RKE keypad, or the RKE transmitter. Power locking and unlocking functions independently of the key position, vehicle speed, or transmission position. The LCM and the DDM activate internal relays to supply the correct power and grounds for the door lock actuators
The DDM receives inputs from the digital transmission range (TR) sensor, ignition switch, brake switch, door lock control switches, lighting control module (LCM), RKE keypad and RKE transmitter. The DDM outputs consists of RKE keypad illumination, door lock actuators, luggage compartment lid release solenoid, and the LCM.

Inspection and Verification
WARNING: If equipped with fire suppression system, refer to Section 419-03 for important safety warnings.
NOTE: Before starting electrical diagnosis, check for mechanical binds by manually operating the door locks. Operate the lock system several times from each switch while observing the operation of all the door locks. Be sure the battery is fully charged.

1. Verify the customer concern.

1. Visually inspect for obvious signs of mechanical or electrical damage.

3. ????????????? Do you have a professional scan tool ?
   ??

You need to understand how they work , do you know about automotive electronic controls ? Your switches are just inputs to the BCM - body control module !
Door Locks Power and Ground
For door lock operation, the IP Fuse Block supplies battery positive voltage, through the 15 amp DR LK/TRUNK fuse, to the BCM. The BCM uses this circuit exclusively to apply power to the door lock actuators. The BCM is also supplied a ground circuit, which it uses exclusively to ground the door lock actuators. When a door lock is pulsed, the BCM internally connects these two circuits to the appropriate lock and unlock control circuits to actuate the locking or unlocking functions.
When diagnosing door lock malfunctions, these circuits must not be confused with the other battery voltage and ground circuits of the BCM. The appropriate wiring schematic must be used to locate the correct circuits. Failure to identify the correct battery voltage and ground circuits of the BCM during diagnosis of door lock concerns may result in misdiagnosis and unneccessary parts replacement.
Passenger Door Unlock Operation
When the BCM detects a transition of either of the door lock switches to the Unlock position, it switches the door lock actuator unlock control circuits to voltage. Since the door lock actuator lock control circuit is at ground potential within the BCM, the passenger door lock actuators transition to the Unlock position.
The door lock actuator unlock control circuits are dedicated control circuits used only for the passenger door lock actuators. This is done so that the driver door may be unlocked individually before unlocking the passenger doors using a keyless entry transmitter or an automatic door unlock function, if programmed. When the keyless entry transmitter is used to unlock the passenger doors, the BCM requires a repeated unlock command before it performs the unlock function. However, when the unlock input is from a door lock switch, a single unlock command is all that is required to unlock all doors.

How to test computer controlled door locks

I would started with the most obvious possibility and checked to be certain all 4 batteries are good even if you just replaced them, check each battery as 1 bad cell will pull down the others. If you find a cell that reads lower than the others, try replacing that one.

You need to reset the lock, so it will be set to the correct handing (left or right hand door).

Open the door and extend the lock bolt. Remove the battery. Press the reset button three times and wait 20 seconds. Push and hold the lock button, while inserting the batteries. Hold the lock button until the bolt starts to move. Allow the lock to complete it's learning cycle.

Program a new code and test.

Synchronization
When
Key buttons operated repeatedly while vehicle out of range and system becomes inoperative.
How
Press key lock or unlock button for approximately 1 second. Manually lock or unlock vehicle. System should now lock or unlock vehicle. If not, carry out programming procedure.
Programming
When
Key added or replaced. System malfunction.
How -

98MY
Keys can only be programmed using diagnostic equipment.
NOTE: A maximum of 4 keys can be programmed.
How - 99MY

Switch ignition ON. Insert key to be programmed into driver's door lock. Lock vehicle manually. Press lock or unlock button. Wait at least 1 second. Press lock or unlock button again. Vehicle horn sounds to indicate correct programming. Keys can also be programmed using diagnostic equipment.
NOTE: A maximum of 4 keys can be programmed.

You might not be pushing the correct sequence of buttons to unlock the door. You should only have to enter in your code to unlock the door, unless there was a problem when the lock was programmed.

Here's a copy of the user manual so you can verify the codes were entered properly and that the lock is set up correctly.

Hope you find this Very Helpful and best regards!

Pls explain if you have electric door locks or not. A seized solenoid (if you do) will preevnt the latch from working...Regardless of whether you do or not, anything wrong with the alternator will give not you door lock issues. You problem is purely mechanical. The electronic function (option) just assists the mechanical (non-powered) door locks. The doors should work; (the lock/unlock/open/close) even with the battery disconnected, using the manual controls.
