Long ago, I put a set of tires on a car and a few weeks later, the tire pressure warning light came on. After verifying that the air pressure in all 4 tires were fine I realized I must have a bad TMPS. I bought one from the dealer and took it to a tire shop near my job for them to install it since you have to pull the tire off the rim in order to replace it. It worked fine. A few months later another sensor went out on a different tire. Repeated the process. A few months after that, it happened again to another TPMS.I made the decision then that in the future, whenever I have to put a set of tires on a car I'll also replace the TMPS's while I'm at it. Might as well while the tire is already off the rim right???My wife's Highlander recently needed a set of tires and I bought these sensors at half the price that the dealer wanted.When the sensors came, they included a card in the package with a set of instructions on how to program them. I'm actually pretty knowledgeable when it comes to cars as I've worked in the automotive industry for many years and the instructions didn't really make much sense to me. Why does it matter if I place the sensors on top of the tires and activate them before installing them??? I did a little research and found that on this model, you have to write down the sensor ID code (in the picture with the red arrow) and program the code to the car's computer using a scan tool (most scan tools don't have this capability, the scan tools that do can cost A LOT of $$$) so it will communicate with the sensor. I followed the procedure (there are videos on YouTube that show you how to program the sensors) and they work perfectly!I seen a few reviews stating that these are not OEM Toyota sensors. One thing I can say is that sometimes, even car manufacturers get their sensors or other parts from a 3rd party vs manufacturing them themselves. You ever heard of the Takata air bag recalls? Those air bags went in all types of Japanese car brands. They were purchased from Takata and installed in their cars at the factory. I can't say for sure if these are the exact same sensors as the ones I would have gotten from the Toyota dealer, but I included a picture of one of the old sensors that was taken off the car and it looks almost identical to this one. If you notice, at the bottom left corner of both the old sensor and this one purchased here on Amazon, they both say Pacific Industrial Co LTD.If you are in the market for a TPMS for your car I would suggest doing what I did. You call the dealer for a price on a new TPMS for your car. When they give you the price say ok, great! Btw, what's the part number? Once you have the part number you can search for one here on Amazon and you will usually find them MUCH cheaper than the dealer.Although these sensors worked out great for me, I would HIGHLY suggest doing your research beforehand to make sure it's something you can handle on your own. Otherwise, just pay a professional to do it and avoid the aggravation.Hope this helps! Good luck!  Read Less
