GM would have to enable the TPMS option in the BCM. Unfortunately, since it was not built with that option, dealers will refuse to do it. You could always swap out your BCM with one that has it activated...... but then you still need to have the VIN on the BCM changed to match your car, the key fobs reprogrammed AND the key resistor values updated, mileage data corrected, so on....

There is a way to clone almost all that stuff, I've done it myself. But it was not worth the effort.

I wonder why they refuse to do it?

Bring in a set of unmounted TPMS sensors and see if you can find a friendly tech to try for you. Assume you will pay either way for their time. Do any research you can to get them stated. If it doesn't work or they all refuse - try more than one GM dealer - return the sensors.

My opinion, it's not worth it, especially since you are in Canada. What about when you install your snow tires? Another $200 for 4 more sensors. I have a 2015 and have to look at that tire light all winter....Yes, I am a cheap wad.....lol
