WARNING: This page is about a different car, the 2019 Chevrolet Malibu. However, it is still accessible from the selected car via links, so may be relevant.

NOTE:

This procedure will clear any learned transmitters from the S25 Garage Door Opener. This will require reprogramming by the customer to reestablish universal home remote functionality.

If available, J 41540 Universal Home Remote Tester may be used to diagnose the S25 Garage Door Opener. To test, press and hold the two outer buttons on the S25 Garage Door Opener for greater than 30 s. The LED on the S25 Garage Door Opener will illuminate for 20 s, then begin to flash quickly for another 10 s. When the LED stops flashing, the system has been cleared and placed into default mode. Place the J 41540 Universal Home Remote Tester so that it is adjacent to the S25 Garage Door Opener. Verify the appropriate J 41540 Universal Home Remote Tester Indicator Lights illuminate when each button on S25 Garage Door Opener the is pressed, one at a time. If the tester does not respond to each button press, replace the S25 Garage Door Opener. If the tester does respond to the button presses, using the Hand Held Transmitter from the J 41540 Universal Home Remote Tester kit, program a single button on the S25 Garage Door Opener. Refer to the instructions provided with the J 41540 Universal Home Remote Tester for programming instructions. Verify the Programmed indicator on the J 41540 Universal Home Remote Tester illuminates when the programmed button on the S25 Garage Door Opener is pressed. If the programmed button does not illuminate, replace the S25 Garage Door Opener. If the button does illuminate, instruct the customer to program the S25 Garage Door Opener to their device. Refer to the vehicle owners manual. If further malfunction occurs, a possible rolling code or incompatibility with the S25 Garage Door Opener will prevent programming.
