The GLK-Class from Mercedes-Benz hit the American market in 2010, and the 2013 model year ushered in a handful of changes. The most notable change for the base GLK350 was an increase in power to 302 horsepower and 273 foot-pounds of torque -- a 34-horsepower and 15-foot-pound increase over the 2012 model. Optional on the 2013 GLK350 was a garage door opener integrated with the rearview mirror, and programming this opener was fairly simple.
Clearing Existing Codes
Insert the smart key into the ignition and turn it to position "2." Press and release the outer two buttons on the rearview mirror, and watch as the indicator light on the mirror lights up yellow. Continue holding the outer two buttons until the indicator light turns green to clear the existing codes from the mirror.
Programming Garage Door Opener
Clear the existing codes, if needed. Press and hold the button you would like to program on the rearview mirror until the indicator light turns yellow. Release the button and observe as the indicator light flashes yellow. Hold your garage door opener two to eight inches from the rearview mirror, then press and hold the open/close button on your garage door opener until the indicator light turns green. Release the button on your garage door opener. If the indicator light turns red, restart the programming procedure and hold the garage door opener at a different distance from the rearview mirror. Proceed to the " Synchronizing the Rolling Code" if applicable.
Synchronizing the Rolling Code
Press the "program" button on your garage door opener. The "program" button is typically on the back of the opener unit, near where it wires into the electrical system in the garage -- see your garage door opener's manual for more details. Press the button on the rearview mirror that you programmed to the garage door until the door opens or closes.
