Question about 2002 Toyota Camry
The power locks work when the car is placed in drive, but will not unlock. The remote does not unlock them nor does the main switch by the driver.
The remote will open the driver's door only.
Where do I start
Do you have a remote starter installed in this vehicle? If so, you body computer is probably compromised. Aftermarket remote starters kills the body ECU with unfortunate regulararity.

I do have a book on the 1996 but no on me but I have had a problem with it the same, Get in and sit in the drivers set and push lock from the in side and then do the same but this time unlock it and then get out and try to use the remote. if no then try to do the same thing but in the passenger side. lock and then unlock. no then call the ford dealer shop and they have a alarm department that will help you and I know because I had then do a job on one of my other cars and I was charged $20.00 he did it on a side job.

Tips for a great answer:
DOOR LKS fuse
Driver door lock actuator
Driver door lock switch
GMLAN serial data link
Keyless entry transmitter
Passenger door lock actuator
Passenger door lock switch
Remote control door lock receiver (RCDLR)
The DR LCK fuse supplies battery voltage to the body control module (BCM) for the power door lock system. The BCM supplies and monitors a reference voltage to the driver and passenger door lock switches through the door lock switch lock/unlock signal circuit. Each door lock switch receives ground at G300 which is also the ground for the door lock and unlock relays located in the BCM. When a door lock switch is placed in the lock position, the reference voltage is switched to ground and the BCM senses 0.0 volts on the door lock/unlock signal circuit. When a door lock switch is placed in the unlock position, the reference voltage is switched to ground through a 1.5k ohm resistor that is internal to each of the door lock switches and the BCM senses approximately 2.9 volts on the door lock/unlock signal circuit. The BCM interprets what position the activated door lock switch was placed in based on the voltage drop.
The BCM, upon receipt of a lock or unlock switch signal, will switch the appropriate door lock/unlock relay coil control circuit to ground causing the appropriate door lock/unlock relay to energize. With the relay energized, voltage is applied to the door lock actuator control circuit causing the door to either lock, or unlock depending on what command was received from the power door lock switch or remote control door lock receiver (RCDLR). When a power door lock/unlock relay is not energized, the switch contacts are normally grounded through the BCM which provides ground to the appropriate door lock actuator for the lock/unlock function being performed. The power door lock/unlock functions are performed by reversing the flow of voltage through the door lock actuator control circuits. The BCM has three internal drivers for the power door lock system. Driver door unlock, passenger door unlock and all door lock. This is done to isolate the driver door lock actuator so it can be unlocked separately from the passenger door. For additional information concerning keyless entry, refer to Keyless Entry System Description and Operation.
This is one you may want to take to dealer or some other ASE certified repair shop ! To do this right you need a Tech 2 scan tool !
Ignition ON, observe the scan tool Door Lock Switch parameter while using the driver and passenger door lock switches. The parameter should change from Idle to Lock and Unlock.
If the value does not change, refer to Door Lock Switch Malfunction.
Command the doors to LOCK and UNLOCK with the scan tool, the door lock actuators should LOCK and UNLOCK when changing between the commanded states.
If one or more doors do not LOCK or UNLOCK, refer to Door Lock Malfunction.

Command the driver door and passenger door lock actuators to LOCK and UNLOCK with the scan tool, the doors should LOCK and UNLOCK when changing between commanded states.
If a door lock actuator does not perform the LOCK and UNLOCK functions, refer to Door Lock Malfunction
