Saved me a lot of time and money! Last year I bought new wheels, tires and TPMS monitors for my 2011 Camaro SS. The TPMS sensors were bought off ebay and I felt like they sent me the wrong ones as I couldn't program them by hand and the tire fitter couldn't get them to install them with their tire monitor. So, I've been driving with the TPS light on for 8 months. I was finally ready to order new sensors and pay $200 for a fresh install when someone on another site recommended I try this monitor. It was $18 so I figured why not. After receiving it and inserting the battery (which is not included) I went to the car, followed the procedure in the manual and after 2 minutes all the sensors were programmed and working! Couldn't be happier!
