Clone your TPMS sensors so that you can switch between two sets of tires without having to ever Relearn your system. Example if you have a set of summer and winter wheels and do not want to have to go to the dealer and Relearn the TPMS every time you switch back and forth. THE WAY IT WORKS. Please let us know if you have any questions. UNMATCHED QUALITY While you’re matching everything, don’t forget our most important feature: the unmatched Genuine German Quality that puts sens. It® in a class by itself. Sens. It® products are designed and rigorously tested in Germany by ALLIGATOR® – the world’s leading supplier of OE tire valves. So you get more durability, better performance, and happier customers.
