KINGBOLEN EL-50448 TPMS Reset Tool

KINGBOLEN EL-50448 TPMS Relearn Tool — one-button tire pressure sensor activation / relearn tool for GM-series vehicles with 315 MHz or 433 MHz TPMS.

• Designed for GM vehicles including Opel, Buick, Cadillac, Chevrolet, GMC, and more (approx. 2006–2023; confirm your model before purchase)
• Completes the sensor relearn procedure after tire rotation, TPMS sensor replacement, or remote door lock receiver module replacement
• Works with original factory TPMS; quickly activates sensors so the vehicle can relearn all 4 tire positions
• Simple one-button operation: set the vehicle to TPMS learn mode → hold the tool against the tire sidewall near the valve stem → press the button until the horn confirms
• Durable PVC housing — dust-proof, wear-resistant, impact-resistant; lightweight and easy to store in the car or toolbox
• Responsive activation — typically finishes sensor relearn in about 1–2 minutes

Important Notes

1. Not compatible with heavy trucks or external / aftermarket TPMS systems. If your vehicle is not listed, it may not work — contact us to confirm.
2. Keep the antenna in the correct position against the sidewall near the valve stem. Different vehicles may need different time to complete all four sensors.
3. Requires a 9V battery (not included).
4. This tool is for TPMS sensor activation / relearn only — it is not a full-system OBD2 diagnostic scanner.
