Looking for location of the keyless remote control module on a 2010 Chevrolet Avalanche LT

behind and below the A/C control

The remote keyless entry (RKE) module for a 2010 Volvo S80 V6 is typically located in the trunk of the vehicle, near the spare tire. It is a small module that is responsible for controlling the functions of the remote keyless entry system, such as locking and unlocking the doors, activating the alarm, and starting the engine using the remote.
To locate the RKE module, you may need to remove the trim panel or carpeting in the trunk. If you are unable to find the module or are unsure of its location, you may want to consult your owner's manual or a repair manual for your specific model of Volvo S80. Alternatively, you can try contacting a Volvo dealership or a mechanic for assistance.

Need to go to the dealer. They have a machine they plug into your car to match the remote to the car.

3. System should now lock and unlock doors to indicate vehicle has entered
programming mode.

4. Press any button on keyless remote once. System should now lock and unlock

Do you know anything about automotive electronic's , control module's ? Serial data communication networks ?
Circuit/System Description
The driver and passenger door lock and side window switches are integrated control module switch assemblies. The DDS and PDS door lock switches are normally open, 2 position rocker type switches, with detents for lock and unlock. The DDS and PDS are directly connected to the respective door lock actuator through the door lock actuator control circuits. When a door lock or unlock function is activated from the DDS or PDS, a serial data message lock or unlock command is sent to the other door switch and body control module.

The rear doors will not lock with the keyless remote, the drivers master switch
