I bought an XTool TP150 that I used to relearn the sensors but any tire shop could do it. It takes 2 min with the tool. The sensors are preprogrammed, but you have to pair them to the ECU.After taking the tires off, I used a VEVOR manual tire bead breaker to break the bead all around (just step on it after the bead is broken) and then to hold the tire down far enough that I could replace the sensor. Windex around the bead / rim to lubricate it and then remove the bead breaker and air it up. No problems on 5 tires, took about an hour all in with an impact to take off / put on the tires.All in, it cost less to buy all of the tools and to do it myself vs what it would’ve cost to have the tire shop do it once. After the initial investment, it’s just the sensors and they’re cheap!

I was skeptical about the quality of this but I decided to try it and it installed easily and appear to be high quality and had no issues after programming it into the car. Please note that you do have to know what you're doing to install these things. You don't just install it and hope it works. You need a tool to program it into your car. In fact this work better than the more expensive unit that I have purchased previously and I like it so much more. The other one doesn't actually activate until the tire starts rotating so the light on my car stays on for a while until it runs for a little bit while but this one works immediately. I have no idea how long the battery on this one will last but if it can last for at least 5 years I would be very happy for the price I paid. It is so much less expensive than the other brands that I won't mention here.

Worked on my 2008 Lexus IS250. The only issue I ran with these sensors is that the tire shops I went to all said they couldn’t program them. All three shops said I needed OEM Lexus sensors and that these from Amazon don’t work. I can safely confirm that the sensors do in fact work and can be programmed easily! The way I did it was I bought a TPMS relearn tool here off of Amazon and it worked like a charm. America’s Tire, Pep boys, and Big O tires were gonna charge me almost 500 dollars to replace the sensors. Don’t let these tire shops scam you these off of Amazon work! What I would recommend is try and finding a honest tire shop that won’t try to upsell you or buy the relearn tool yourself. It’s easy!!! Good luck!

Works great 2007 Lexus rx350.it program to scan tool right away.my only concern is how long will the battery will last?I hope I get five years of it.

Recently purchased used auto with dash light blinking. Took these to the repair shop for installation. Mechanic said they chsrge $60 per sensor to repair. Saved a bucket of money. Thanks for a great product.

I liked that the sensors seemed like they were quality made, the valve stems seemed solid and the mechanic was able to mount/install them on my tires for around $100 labor. I don't like that after just over 2 months of being installed, the TPMS light is on again, and the mechanic showed me with his sensor that one of the 4 is no longer working. I guess I'll just by another set of 4 but only replace one at a time to save on the installation costs and keep 3 for spares and keep my fingers crossed.EDIT - after posting this review, I was contacted by the seller who offered to refund/replace the bad sensor, so I'll revise to 4 stars. The labor to have the sensor installed is more of a cost concern than the devices themselves. They do seem like a quality product (good sturdy metal valvestems, appears well assembled), so maybe I just got unlucky.

Had these installed at Walmart. The shop was completely incompetent and crushed 2 of the seals and one was split due to the improper installation. They gave me my car back and said they installed them but could not program them. When I asked which one would not program they just stared at me, then the brightest of the 3 stooges told me I would have to take it to the lexus dealer to have it done.10 miles later my wheel started to pull hard to the left and there was a wicked vibration, then the front left wheel blew out ( the tires were installed 1 week prior and the sensor error appeared 1 day after installation.I went to a non getto walmart and they showed me the torn seals and claimed they were installed incorrectly. Once they were balanced they programed them to the car in less than 15 minutes.I originally filled a return for these sensors and was furious with my self for not being mindful of the reviews.The fact is that all 4 sensors worked the way they were supposed to and it was the malicious incompetence of 3 people attempting to do job that they were clearly not capable of performing.

Very affordable and good for oem replacement. $14 per each tire paid to car shop to install and it is much cheaper than buy and installing by car lot or tire shops.
