2021 Chevrolet Silverado 2500HD Owners Manual - Universal Remote System

Universal Remote System

If equipped, these buttons are in the overhead console.

This system can replace up to three remote control transmitters used to activate devices such as garage door openers, security

systems, and home automation devices. These instructions refer to a garage door opener, but can be used for other devices.

Do not use the Universal Remote system with any garage door opener that does not have the stop and reverse feature. This includes any garage door opener model manufactured before April 1, 1982.

Read the instructions completely before programming the Universal Remote system. It may help to have another person assist with the programming process.

Keep the original hand-held transmitter for use in other vehicles as well as for future programming. Erase the programming when vehicle ownership is terminated. See “Erasing Universal Remote System Buttons”

later in this section.

To program a garage door opener, park outside directly in line with and facing the garage door opener receiver. Clear all people and objects near the garage door.

Make sure the hand-held transmitter has a new battery for quick and accurate transmission of the radio-frequency signal.

For questions or programming help, see www.homelink.com/gm or call

1-800-355-3515. For calls placed outside the U.S., Canada, or Puerto Rico, international rates will apply and may differ based on landline or mobile phone.

Programming involves time-sensitive actions, and may time out causing the procedure to be repeated.

To program up to three devices:

Hold the end of the hand-held transmitter about 3 to 8 cm (1 to 3 in) away from the Universal Remote system buttons with the indicator light in view. The hand-held transmitter was supplied by the manufacturer of the garage door opener receiver.

Press and release one of the three Universal Remote system buttons to be programmed. Press and hold the

hand-held transmitter button. Do not release the hand-held transmitter button until the indicator light changes from a slow to a rapid flash or continuous light. Then release the hand-held transmitter button.

Some garage door openers may require substitution of Step 2 with the procedure under “Radio Signals for Some Gate Operators” later in this section.

Press and hold the newly programmed Universal Remote system button for

five seconds while watching the indicator light and garage door activation.

If the indicator light stays on continuously or the garage door moves when the button is pressed, then programming is complete. There is no need to complete Steps 4–6.

If the indicator light does not come on or the garage door does not move, a second button press may be required. For a second time, press and hold the newly programmed button for five seconds. If the indicator light is continuously lit,

or the garage door moves, programming is complete.

If the indicator light flashes rapidly and the garage door does not move, continue with programming

Steps 4–6.

Learn or Smart Button

After completing Steps 1–3, locate the Learn or Smart button inside the garage on the garage door opener receiver. The name and color of the button may vary

by manufacturer.

Press and release the Learn or Smart button. Step 6 must be completed within 30 seconds of pressing this button.

Return to the vehicle and firmly press and hold the trained Universal Remote system button for two seconds and release. Repeat the “press/hold/release” sequence up to three times to complete

the training process.

The Universal Remote system should now activate the garage door.

Repeat the process for programming the two remaining buttons.

For questions or programming help, see www.homelink.com/gm or call

1-800-355-3515. For calls placed outside the U.S., Canada, or Puerto Rico, international rates will apply and may differ based on landline or mobile phone.

Some radio–frequency laws and gate operators require transmitter signals to time out or quit after several seconds of

transmission. This may not be long enough for the Universal Remote system to pick up the signal during programming.

If the programming did not work, replace Step 2 under “Programming the Universal Remote System” with the following:

Press and hold the Universal Remote system button while pressing and releasing the hand-held transmitter button every

two seconds until the signal has been successfully accepted by the Universal Remote system. The Universal Remote system indicator light will flash slowly at first and then change to a rapid flash or continuous solid-light. Proceed with Step 3 under “Programming the Universal Remote

System” to complete.

Press and hold the appropriate Universal Remote system button for at least one-half second. The indicator light will come on while the signal is being transmitted.

Erase all programmed buttons when vehicle ownership is terminated.

To erase:

Press and hold the two outside buttons until the indicator light begins to flash. This should take about 10 seconds.

Release both buttons.

To reprogram any of the system buttons:

Press and hold any one of the buttons. Do not release the button.

The indicator light will begin to flash after 20 seconds. Without releasing the button, proceed with Step 1 under

“Programming the Universal Remote System.”
