Understanding HomeLink and Car2U Systems
HomeLink and Car2U are popular in-car wireless control systems that can be programmed to operate various devices, including garage door openers, gate operators, and even home lighting. These systems eliminate the need for multiple remotes cluttering your car. This guide focuses specifically on programming these systems to your commercial garage door opener.
Programming HomeLink for Rolling Code Garage Door Openers
Rolling code technology enhances security by changing the access code each time the remote is used. Most modern garage door openers utilize rolling code. Genie’s rolling code is known as Intellicode, while LiftMaster, Chamberlain, and Sears systems use Security Plus. Here’s how to program your HomeLink system for a rolling code opener:
- Clear Existing Programs: Begin by resetting your HomeLink system. Press and hold the two outer HomeLink buttons simultaneously until the indicator light flashes rapidly. This may take up to a minute. Ensure your car key is in the auxiliary position and the car door is closed for this step to work correctly.
- Sync with Handheld Remote: Select the HomeLink button you wish to program for your garage door. Hold your handheld garage door remote close to the selected HomeLink button. Press and hold the button on your handheld remote and the chosen HomeLink button at the same time. Continue holding both buttons until the HomeLink indicator light flashes rapidly. This step establishes your in-car system as a transmitter for your garage door opener.
- Locate the “Learn” Button: Now, you need to personalize the connection by using the “Learn” button on your garage door opener motor. This button is typically found on the motor head unit, often near the antenna wire. For Genie openers, it’s commonly behind the light lens. For LiftMaster, Sears, and Chamberlain models, look for a colored square button (red, green, or purple) near the terminal screw board. Genie “Learn” buttons will have a red indicator light that flashes when pressed, while Sears/LiftMaster buttons have a green, amber, or purple indicator light that illuminates steadily.
- Engage the “Learn” Mode: Press the “Learn” button on your garage door opener. The indicator light will activate, either blinking on Genie openers or staying lit on Sears/LiftMaster/Chamberlain openers, indicating it’s in learning mode.
- Finalize Programming: Return to your car and press the programmed HomeLink button multiple times to complete the process. For Genie systems, press the button three to four times until the garage door begins to move. For LiftMaster, Sears, or Linear Megacode systems, press and hold the programmed HomeLink button until the garage door opener light flashes. Your HomeLink system is now successfully programmed to your rolling code commercial garage door opener.
Programming HomeLink for Fixed Code Garage Door Openers (Pre-1996 Models)
Fixed code openers, predominantly found in units manufactured before 1996, use DIP switches for setting the code. These switches are usually located inside your handheld remote, near the battery. Here’s how to program your HomeLink system for a fixed code opener:
- Clear Existing Programs: Just like with rolling code, begin by clearing any pre-programmed settings in your HomeLink system. Press and hold the two outer HomeLink buttons until the indicator light flashes rapidly. This reset process may take up to a minute and usually requires the car key to be in the auxiliary position and the doors closed.
- Sync with Handheld Remote: Press and hold the HomeLink button you want to use for your garage door while simultaneously pressing and holding the button on your handheld remote. Keep both buttons pressed until the HomeLink indicator light starts flashing rapidly.
- Test the Connection: Press the programmed HomeLink button to test if it operates your garage door.
- Confirmation: If your garage door opens or closes, your HomeLink system is now programmed to your fixed code garage door opener.
Programming Universal Home Remote (UHR) or Car2U for Rolling Code Openers
For vehicles equipped with Universal Home Remote (UHR) or Car2U systems, often indicated by three LED lights above the buttons, follow these steps to program a rolling code garage door opener:
- Initiate UHR/Car2U Programming: Press and hold the two outer UHR/Car2U buttons simultaneously for two seconds, then release. Ensure your car key is in the auxiliary position and the car door is closed for this step.
- Activate “Learn” Mode on Opener: Put your garage door opener into “Learn” mode. Locate the small square colored button or round black “Learn” button on the garage door opener motor. For Genie openers, these are typically behind the light bulb cover. You may need a ladder for safe access.
- Sync with UHR/Car2U: Once the “Learn” button is activated, the LED light on the garage door opener will illuminate. For Genie openers, the LED will blink. At this point, press and hold the UHR/Car2U button you want to use to control your garage door.
- Activate and Lock Program: Wait for the garage door to activate. Once it moves, release the button, and then press it again to finalize and lock in the programming.
- Programming Complete: Your UHR or Car2U system is now programmed to operate your rolling code garage door opener.
Programming Universal Home Remote (UHR) or Car2U for Fixed Code Openers (Pre-1996 Models)
Programming fixed code openers with UHR or Car2U requires understanding DIP switch settings. Refer to the chart below to identify your DIP switch configuration.

- Initiate UHR/Car2U Fixed Code Programming: Press all three UHR/Car2U buttons simultaneously and release. Ensure your car is in auxiliary mode and doors are closed.
- Enter DIP Switch Settings: Enter your garage door opener’s DIP switch settings into your UHR/Car2U system. Using the chart above as a guide, press the corresponding UHR/Car2U buttons for each DIP switch position. For example, if the first switch is “Up,” press the left button. If the second switch is “Down,” press the right button.
- Confirm DIP Settings: Once all DIP switch settings are entered, press all three UHR/Car2U buttons simultaneously and release.
- Test Operation: Press and hold the UHR/Car2U button you want to use for operating your garage door and watch for the garage door to activate.
- Lock Program: When the garage door activates, release the button and press the selected button again to lock in the programming.
- Programming Complete: Your UHR or Car2U system is now programmed for your fixed code garage door opener.
