Good morning, on the caravans it is a one key opens and starts it vehicle. However you might try spraying some wd-40 into the lock itself and see if that helps you be able to turn the key, also someone could have replaced the back hatch and not changed the lock. I would like to believe it is just stuck so try the wd-40 first. Hope this helps and have a great day.
Thanks,
Joey

Why won't the passenger door unlock?


Door Lock System Controls
The Power Door Lock System is controlled by the body control module (BCM) and can be activated by any one of the following:
?€¢
A door lock switch lock or unlock actuation

?€¢
A keyless entry transmitter actuation

?€¢
An automatic door lock or unlock actuation

?€¢
A last door closed locking (LDCL) actuation
If the driver door cylinder switch feature of the vehicle is functional, the locks may also be operated by a driver door cylinder switch lock or unlock activation.
Power Door Lock Switch Operation
Each door lock switch is wired to the body control module (BCM) through a separate door lock/unlock signal circuit. While these circuits are separated between the BCM and respective door lock switch, they are connected into a single circuit within the BCM. The BCM supplies voltage through the door lock/unlock signal circuits to each door lock switch. When either door lock switch is operated, this supply voltage is pulled to ground, providing the BCM with the required lock or unlock signal. In order for the BCM to distinguish between a lock and unlock signal, the lock switch contains two separate paths for this voltage to flow to the same body ground. When the switch is operated to the unlock position, the supply voltage flows to ground through a 1.5 K?© resistor. When the switch is operated to the lock position, the supply voltage flows to ground through a different part of the switch circuit, which has no resistor. The BCM then interprets the flow of voltage as a lock or unlock request and powers the door lock actuators to the appropriate lock or unlock position.
I'll post a youtube video on how to test the power door locks computer controlled , check it out ! Your problem could be a switch or the lock actuator , BCM , wiring etc.... you need to test it to see !

You can purchase new Remote Keyless Entry (RKE) transmitters from the dealer or you can order them online at the web sites listed below or several others. Your vehicle provides for programming the RKE transmitters without the use of a scan tool. Follow the instructions below.

2000 PONTIAC GRAND AM RKE TRANSMITTER PROGRAMMING

WITHOUT A SCAN TOOL

1. Close all vehicle doors. Remove key from ignition lock cylinder

NOTE: STEPS 2 AND 3 MUST BE COMPLETED WITHIN 25 SECONDS OF PRESSING THE DOOR UNLOCK SWITCH
2. Press and hold door UNLOCK switch. While holding UNLOCK switch, insert and remove the key in the ignition lock cylinder twice. Do not rotate the lock cylinder.
3. Insert the key a third time, leaving the key in the lock cylinder. Keep the lock cylinder in the LOCK position for the remainder of the procedure. Release the door UNLOCK switch. The chime will sound 3 times to signal that the programming/diagnostic mode is active.
4. Press and hold LOCK and UNLOCK at the same time on the RKE transmitter for approximately 4 seconds. The chime will sound 2 times signaling that the transmitter has been programmed.
5. Repeat step 4 for each transmitter being programmed. (You can program up to 4 transmitters.)

6. To exit program mode, turn the key to the RUN position then back to the LOCK position and remove the key. Your transmitters should now work to lock and unlock your doors.

Can not lock car by key remote . toyota rav 4 53 plate


If your car has an alarm with a separate remote, it is a separate system and it is probably self-arming. When you lock the doors with the key central lock, the alarm gets armed by the RAV4 being OFF and the door locking action. When you unlock the doors with the key, the alarm is still armed because the key is not comunicating with the alarm just the cars factory keyless system.
