Review on 🔧 ACDelco GM OE 23445327 TPMS Sensor for Tire Pressure Monitoring System by Larry Breeze

Worked like a charm, still lights up after Walmart shipped my new tires. I knew because they don't have a programmer. Simply put the key in the "on" position and press and hold the lock and unlock buttons at the same time until you hear a beep. Then start with the driver's left wheel. Deflate for about 3-5 seconds and you should hear a beep. Then to the passenger side and repeat the process until you get to the back of the driver. After you're done with that, you should hear 4 beeps letting you know the reset was successful. Then lift the tires back to the desired location. The light will go out and your gauges should show all four tire pressures again.
