I also bought the Kent-Moore tool.. And yes, 30 seconds is no exaggeration.. Super easy to do..
Just use your steering wheel control to bring up your tire pressure monitor screen.. Then press and hold the select button until the cars horn blows once.. Leaving the key fob in the car, start at the left front wheel.. Point the reprogramming tool at the tire by the valve stem, and press the button..
When the programing is complete for that tire, the horn will toot once.. Proceed clockwise around the vehicle, pointing the tool at each tire and waiting for the horn to toot.. Once you've completed the reprogramming on the left rear tire.. The horn will blow twice.. This tells you that the reprogramming has been successfully completed.. 30 seconds tops..
