Hi Steve, thank you for reaching out. This TPMS sensor for your 2013 Ram 1500 Longhorn Laramie comes pre-programmed from the factory and does not require additional programming before installation. However, after replacing the sensor, you will need to perform the vehicle’s TPMS relearn procedure for proper TPMS function.
