I have ordered 5 of these for 07 4Runner. When they were installed at a tire shop one didn't transfer at all so I asked to keep the old one in stock and sent the defective one back for replacement. About a week later the TPMS light started blinking again. I went to the tire shop again to replace the sensor. It was a new front left one that was already broken so I replaced it with a spare. Will now send the defective one in for another exchange and then back to the tire shop to fit the spare tire. I really hope this will happen!
