The driver side door of my 2003 toota camry will

no you needs a new lock actuator on that door its about $90 installed,
all the locks are on same circuit . sorry about the bad news :(

it is not the actuators, try a different remote, you may have an issue with the car security system/body computer not functioning on the unlock driver door command, one press of remote is unlock driver door and 2 presses is unlock the other doors.

Does the Driver side door lock and unlock from the lock switch inside? If not then you have a bad motor or bad connection to the lock/unlock motor inside the door.

1. Driver door open and unlocked. Key out of the ignition
2. Insert the key and remove 2 times in 5 sec.
3. Close and open driver door 2 times in 40 sec.
4. Insert the key and remove it again from ignition.
5. Close and open driver door 2 times in 40 sec.
6. Insert the key in ignition,
7. Close the door,
8. Turn to on and back to lock in 1 second intervals. 1 time for add, 2 times for rewrite, 3 for confirmation 5 for prohibition. (yes, there is no “4”)
9. Remove the key
10. Power lock will cycle to confirm
11. For add or rewrite mode within 40 sec of the confirmation,
A. press “lock” and “unlock” buttons of the FOB at the same time between 1 and 1.5 seconds.
B. within 3 sec press “Lock” button for more than 1 sec and release.
C. If it’s correct, the power door lock will cycle once. If it’s wrong the door lock will cycle twice.

lock actuator is bad...

Remove the door panel and reconnect the plug going to the front driver door lock or, if you can hear the motor trying to engage the door lock cam when you press the lock/unlock remotereconnect the door lock lever bar

I believe this was done as a safety feature. It stops a potential car hyjacker from sneaking in the passenger door when you open the driver door. I know recent Hyundai models are set up such that if you turn the key in the driver's door once it only unlocks the driver's door. If you turn it twice in quick succession it unlocks all of the doors. Maybe the Camry is set up the same way.

you have to change your lock system in the driver side. it is gone.

You may have inadvertantly locked the passenger windows by pressing the little button to the right of the door locks (on the driver side). It's a push to lock/push again to unlock type button, so try pushing it--if it stays down, then that wasn't the problem. If it comes up, then try the window. I hope that helps
