If you bought these tires thinking you would take them to a tire shop and get rid of the TPMS light then you are an idiot and should read the description very carefully! You must use the Autel tool if you want to program automatically. We buy a lot of these sensors, we also have a couple of Autel tools that program them. You copy the old sensor via obd or clone and push the program. We need about 60 seconds to complete everything. This year we have installed about 80 of these systems and in the two years we have used them there has never been an outage. Again, if you don't have an Autel tool or one of the Autel scanners with the tpms option, don't buy them. You only leave bad reviews because you can't read about a product that works the way it's supposed to.
