Autool Autel MaxiTPMS PAD TPMS Sensor Programming Accessory Device (1pcs MAXITPMS PAD)

Relatively inexpensive option for DIY TPMS. I wanted to clone sensors to install in the winter tire/wheels. Cloned sensors should not require the TPMS to relearn new codes, since the 4 ID's on each set are the same. Thus, avoiding the $80 trip to the dealer for relearning the TPMS codes.Reading already mounted sensors on the summer tires had a hitch. After many read-fails, thought maybe a status change would "wake" the sensor, so I released about 5 lb out of each tire, and sure enough, sensor went live, and could be read (late model Subaru's).

Not as promised in in the product details. Missing 4 TPMS as per description of item.Now need to order separately.
