Since the early 2000s, Jeep Grand Cherokees have come equipped with some of the manufacturer's top technologies. These capabilities include an on-board radio transmitter that can control a variety of tools, including a garage-door opener. You can program the Jeep's transmitter to act as a garage-door opener in just minutes from your home. Be sure you are in or just outside of your garage and that your garage-door motor is working.
Turn off the engine of the car and press and hold buttons 1 and 3 on the Jeep's transmitter for 20 seconds to erase previous codes. Release them when the display reads "Channels Cleared."
Hold your garage-door remote 1 to 3 inches from the Jeep transmitter.
Press and hold the open button on your handheld remote and simultaneously press the button you wish to program on the Jeep's transmitter. For example, if you want button 2 to be the one you use to open your garage door, press button 2 while pressing the open button the remote.
Release the button once you hear a beep and the display reads "Trained."
Press the "smart" button on your garage door motor. This button is usually located on the back or side of the motor near the antenna wire and light lens.
Return to your vehicle and press and hold the programmed button in your Jeep for 2 seconds. Release and press and hold the button for another 2 seconds to complete the programming sequence. You will now be able to use the vehicle's transmitter to open your garage door.
