I've been struggling with a set of bad or never programmable TPMS sensors in my TrailBlazer for 7 years and I've finally had enough. I needed to buy tires so I did some research and ended up buying an Autel TS408 + 4 pcs Autel TPMS sensors. I pre-programmed the sensors into my TrailBlazer using the TS408 before going to a tire shop to have them fitted with new tires. Once installed, I simply put my TrailBlazer into programming mode (thanks to the helpful TS408 manual) and programmed the sensors for my car. I could read the tire pressure on the dash and the NO MORE TPMS light on the dash came on too!
