Where is the key fob transmitter located in a pont g6 2006

Looking at the service info for your Uplander, it has Remote Control Door Lock Receiver technology, so keyless entry should work if you have a capable key fob.

Your Uplander will need the key fob programmed by a service center or dealer with the technology to program those GM vehicles that can't be done manually (i.e. Tech 2 scan tool).

The scan tool must stay connected until all of the transmitters are programmed.
Invalidate All
This procedure will erase all keyless entry transmitters from memory.
Install a scan tool.
Turn ON the ignition with the engine OFF.
With the scan tool, select Body.
Select Remote Control Door Lock Receiver (RCDLR).
Select Module Setup.
Select Program Key Fobs.
Select Invalidate All Fobs.
Follow the scan tool on screen instructions.
Transmitter Slot Programming
Transmitter slot programming allows a single transmitter to be programmed into a specific slot without affecting any of the other programmed transmitters. By using slot programming, the transmitter originally programmed to a specific slot is erased and the new transmitter learned in its placed.
Install a scan tool.
Turn ON the ignition with the engine OFF.
With the scan tool, select Body.
Select Remote Control Door Lock Receiver (RCDLR).
Select Module Setup.
Select Program Key Fobs.
Select the key fob desired to be programmed.
Follow the scan tool on screen instructions.
Remove the scan tool.
Exit the vehicle. Operate all functions on transmitters to verify correct system operation.

Your car's fob can't be programmed like that .
Transmitter Programming
Important: Up to 4 transmitters can be programmed. Do not operate or program the transmitters in the vicinity of other vehicles that are in the keyless entry program mode. This prevents the programming of the transmitters to the incorrect vehicle. The order in which the transmitters are programmed is important. The first transmitter programmed will be transmitter #1, and the second transmitter programmed will be transmitter #2. Use care to program the transmitters correctly.
Important: All key fobs must be programmed each time any one fob is programmed. The scan tool must stay connected until all of the transmitters are programmed.
Install a scan tool and navigate to the BCM Module Setup menu.
Select Program Key Fobs.
Follow the scan tool on-screen directions.
When the programming operations have completed, operate the transmitter functions to verify correct system operation.

What is year--make--model?
The key fob is a transmitter so there has to be a receiver in the vehicle. At the moment, I can't tell if problem with transmitter or receiver? Can you try a different key fob? Where applicable, if key fob needs to be programmed, maybe the info is in your owners manual?

How was it programmed ? Was a scan tool used ?
Program All Key Fobs
To complete this programming operation, all keyless entry transmitters associated with the vehicle must be available for programming. Once placed into program mode, all previously programmed transmitters will be erased from memory upon the receipt of the programming signal from the first transmitter.

1. Close the lift gate.
2. Ignition ON, access the scan tool Lift gate Module Setup menu and select Program All Key Fobs.
3. Follow the scan tool on screen instructions in order to program the transmitters. Select "Start" on the scan tool to enter the program mode.
4. As each transmitter is successfully programmed, the scan tool will show how many transmitters have been placed into memory.
5. When all transmitters are programmed, exit the program mode by selecting "Stop" on the scan tool. The vehicle will not respond to the transmitters until the program mode is exited.
6. Operate the transmitter functions in order to verify correct system operation.

Program Individual Key Fob
If there are less than four keyless entry transmitters programmed to the vehicle, an individual fob transmitter can be added. This method will not erase previously programmed transmitters from memory.

1. Close the lift gate.
2. Ignition ON, access the scan tool Lift gate Module Setup menu and select Program Individual Key Fob.
3. Select "Program additional Key Fob" on the scan tool.
4. Follow the scan tool on screen instructions in order to program the transmitter.
5. Operate the transmitter functions in order to verify correct system operation.

The keyless entry system has the following main components:
• The transmitters
• The passenger door module (PDM)
The PDM communicates with the body control module (BCM) through the keyless entry serial data circuit. When you press a button on a transmitter, the transmitter sends a signal to the PDM. The PDM sends a request to the BCM and the BCM performs the appropriate function.

The receiver for the fobs is located in the rear hatch, and it needs to be reprogrammed to the fobs. Try the following procedure;

1. Close all the vehicle doors.
2. Insert the ignition key into the ignition lock cylinder.
3. Press and hold the door unlock switch.
4. While holding the door lock switch in the unlock position, cycle
the ignition ON, OFF, ON, OFF.
5. Release the door unlock switch. The doors will lock and unlock to
confirm the program mode.
6. Press and hold the LOCK button and the UNLOCK button
simultaneously on one transmitter. After a delay of approximately 15
seconds, the doors will lock and unlock to confirm the programming of
that transmitter.
7. Repeat the previous step to program up to four transmitters.
8. Turn the ignition switch to the RUN position in order to exit the
keyless entry transmitter mode.
9. Operate the transmitter functions in order to verify correct
system operation.

The sensor is located inside the BCM (body control module)

all keys/car have to be programmed at the same time.using nissan diagnostic machine.you could try a quickfit centre (if they have correct machine)

Transmitter Programming Procedure
Close all the vehicle doors.
Insert the ignition key into the ignition lock cylinder.
Press and hold the door unlock switch.
While holding the door lock switch in the unlock position, cycle the ignition ON, OFF, ON, OFF.
Release the door unlock switch. The doors will lock and unlock to confirm the program mode.
Press and hold the LOCK button and the UNLOCK button simultaneously on the transmitter. After a delay of approximately 15 seconds, the doors will lock and unlock to confirm the programming of the transmitter.
Turn the ignition switch to the RUN position in order to exit the keyless entry transmitter mode.
