Resetting the TPMS '12 Liberty?

My better half has a '12 Jeep Liberty 3.6L and last week the TPMS alert light came on. I inflated all the tires to a little higher than recommended and she drove for days and it never reset. Thinking it might be the spare I dropped that down and was right around 0psi so I inflated that, too. Still the light will not go off. So looking online I found many, many, many sources stating things like:

Without starting the car, turn the key to the “On” position. Press the TPMS reset button and hold it until the light blinks three times, then release it.

Many stated the TPMS reset it below the steering wheel or to the right of the steering wheel. Search and search and search and don't see any TPMS reset button. Where the h3ll is that button???? Have a code reader that can do resets but have never done that before and would prefer doing the TPMS reset button method.

Any idea where the TPMS reset button is on a '12 Liberty or how to get the light to turn off?

The TPMS light generally indicates that one or more of the TPMS sensors are worn out, if the tire pressure are where they should be.
Drive up to any Discount Tire store and they'll be happy to check them for you for free, it only takes a few mins for them to walk around the vehicle with their magic wand and see if the sensors are transmitting.
These are common wear items, as they operate on tiny batteries. They usually need replaced every 3-5 years.
It's a good idea to do them when you get new tires if they're more than a few years old.

I have a code reader that I got but never even unpacked. It from Amazon, Kobra Newest Version OBD2 Scanner Car Code Reader - Universal Auto OBD Car Diagnostic Tools for All Cars, Automotive Check Engine Readers with Reset. Anyone know if (and how) you can use this to reset the tire pressure warning light?

Code readers need to specifically support ABS codes, most don't. And they can't physically check the sensors.
Did you have the sensors checked as I suggested?
Does the light flash for a minute when you start the Jeep? This would be another hint of a bad sensor.
If one is bad, the light will not go away no matter what.

Haven't had a chance as this is my fiancée's Liberty and I don't drive it. I'll see how the light acts and try to get her to go have them checked.
