I'm NOT sure on any of this, I had done a little reading in the past, so take this with a grain of salt.
The internal battery on the sensors last 8 yrs, so if you're going to change tires on a near 8 y.o. car or older, it would save a lot more money in the long run to change the sensors with the tires. (changing sensors require removing/reinstalling and balancing the tires). The battery is NOT changeable, you have to replace the sensor.
Some vehicles require programming to recognize new sensors, some do NOT, and will automatically recognize the new sensor in 10 miles of driving. I "think" the Commander will automatically recognize new sensors, if they are the correct sensors for it.
What complicates this even more is the new aftermarket sensors coming available, and some of them are universal sensors that require programming to mimic the exact sensor for a particular car.
It is my impression, i.e. I'm NOT positive, you can order online specific aftermarket sensors for the Commander (aftermarket will use different valve stems, so get all the parts) far cheaper than tire stores or OEM sensors at the Dealer, and install them. As long as they are the "specific" sensor for Commanders and NOT universal ones, you will NOT need any programming.
Check your state laws and inspection, we can go round and round about if TPMS is required, what it comes down to is if your car will pass inspection without it.
From what little I know about the system, the only way to get the TPMS light to go out without a fully working system, is to go into the dash and remove the light. And I "think" the Commander has LED's soldered into the circuit board for warning lights, meaning you have to do some delicate circuit board surgery. You can remove all the other modules and equipment, that will still light the warning light, you will have stored cores for TPMS problems, because Gateway module will try to talk to the TPMS over the CAN Nework and set a code for NOT seeing it. Since TPMS was mandatory on Commanders, i.e. no option to NOT have it, I highly doubt the vehicle's software was written to be able to reconfigure to NOT have it. I "think" disabling the light physically is your only option.
