These don't initialize like most.
So I replaced two of my bad sensors with these and spent several hours trying to get them to program. Like most, they will not initialize with a scanner. You have to write down the number off of the sensor because they likely have to be rolling down the road to transmit. Once I recorded the numbers and programmed them to the car they worked great. Just make sure whoever installs them writes down the unique ID number if your car is not self-learning. In my case it was a 2009 Toyota Yaris. Worth every penny, compatible with my vehicle and fit just like the OEM?

Worked well for about 1 week, then issues
All 4 sensors worked well for about a week. One sensor started to malfunction and not show proper air pressure, causing the low tire pressure to come on, when all are at proper pressure.

Trustworthy
Had to wait a couple of months before I could take them to Discount Tire for installation. Service man put the scanner to them and determined that the batteries were already dead. Marsflex saw my review and immediately replaced the entire order with new modules. . Very happy with the integrity of the company and the manner in which they responded. I recommend this company and the fine people running it. Thank you! !

Pre-Programmed TPMS tire sensors
I was hesitant with all the negative comments from the web about buying non authorized TPMS manufactured sensors. These sensors worked just like the original ones. Very happy with them even if they last only half the time I will still be way ahead of the game! The car did not automatically recognized these sensors I had to program them into the car's computer. Buying the pramming tool and the sensors was still cheaper than buying the car's brands which it would not accept unless it was programmed into the car which is not free. If your one of your sensors are not working they others are not far behind! So get them all replaced together. Now my car uses 5 but I only got 4 because the spar has never been used and the tread design on the new tires are totally different so the spare will always be a spare for emergencies, so when it finally stops working I will buy another sensor and replace it then or sooner if it I get a super deal on one! Oh,did I say I'm totally happy with this purchase? I am!!!
