Simple to use, sensors are cheap and simple to install.
In the last few weeks I have sold more TPMS work then I ever thought I would. Programing sensors is fast and training them to the car is also quick.
Removing old sensor only requires breaking the bead on one side and remove old sensor. Install new sensor and rebalance tire. I did 5 sensors for one car in about 35-40 mins. Programing takes about 5 mins.
