Re-programming Door Locks

That can be the problem but let's look at the fuses and here are the door lock wiring diagrams to help you see how the system works (below).

Door Lock programming:

When the battery is disconnected, the ADL mode returns to the default setting (Mode A). The following procedure must be used to set the ADL function to Mode B whenever the battery has been disconnected.

Initialization Procedure

Perform the following procedure to initialize the ADL function to Mode B.
1. Move the shift lever into the "P" position and close all doors. 2. Turn the ignition switch to the "ON" position. 3. Within 10 seconds after the ignition switch is turned to the "ON" position, push and hold the rear side (unlock position) of the door lock switch for 5 seconds. 4. All doors will automatically lock and unlock when you release the power door lock switch. ^

This indicates that the ADL function is set to Mode B. If all doors do not lock and unlock, the time the switch was held may have been too short or too long. Perform the procedure over again starting from step 1.

If this doesn't work do a head system reset by removing the negative battery cable and holding it to the positive cable for 5 minutes this will discharge the capacitors and reset the system

Please check the fuses

Check out the diagrams (Below). Please let us know what happens.

If the door unlock function is pressed on the remote only the driver's door will unlock. Also will not unlock by inserting the key in the driver's door lock and turning it twice. Will not open by pressing the Door Lock control on the driver's door or any other door. Each lock has to be manually unlocked from inside the auto. Where do I need to look? I surely will appreciate it. Thank You!

the remote may have to be re programmed. the dealer can do it for you.

If the remote was the only method that did not operate the locks I would agree that a re-program would be in order. But, since the Key nor the lock switch inside will unlock the other three doors I'm skeptical of the remote being out of program. I do appreciate your reply and suggestion but I need more please. Thank you!
