Programming your Acura’s HomeLink system to operate your garage door is a convenient feature that eliminates the need for a separate remote. This guide provides a step-by-step process to easily program your Acura HomeLink system to control your garage door opener. Whether you have a standard garage door opener or a rolling code model, this tutorial will walk you through the necessary steps to get your Acura seamlessly integrated with your garage.
To begin, ensure you have the following items ready:
- Your Acura vehicle
- A handheld remote transmitter that is already programmed to your garage door opener
- A small step ladder (optional, for easier access to the garage door opener unit)
Let’s get started with the programming process.
-
Prepare Your Vehicle and Garage Door Opener
Begin by positioning your Acura vehicle close to your garage door. Parking inside the garage is ideal, but ensure there’s enough clearance for the door to open and close during the programming process. It’s also helpful to have a step ladder nearby to easily reach the training button on your garage door opener unit. Locate the training button on your garage door opener. This button is often found on the garage door opener motor unit in the garage. In many models, it’s behind the light bulb cover.

Locate and Test Your Garage Door Remote Transmitter
You will need a working remote transmitter that originally came with your garage door opener. This remote is essential for teaching your Acura’s HomeLink system the correct frequency and code. If you’ve previously used this remote in another vehicle, it will work for this process. Typically, these remotes are small, rectangular devices with one to three buttons and a clip for attaching to a sun visor.
If you cannot find your original remote, you’ll need to purchase a compatible remote transmitter for your garage door opener. Follow the instructions provided with the new transmitter to link it to your garage door opener before proceeding to program your Acura HomeLink.
To link a remote transmitter (if needed):
- Press the “training” or “learn” button on your garage door opener unit.
- Within 30 seconds, press and hold the button on the remote transmitter.
- Wait for the garage opener light to blink or for another indicator (refer to your garage door opener manual). This blinking indicates the remote is now linked.
- Press the button on the transmitter to ensure it successfully opens and closes your garage door.
-
Turn on Your Acura’s Accessory Mode
Enter your Acura and press the “Start” button once without pressing the brake pedal. This will turn on the Accessory ON mode, which is necessary for programming HomeLink. If your Acura has a key-based ignition, turn the ignition key to the “ON” position.
-
Clear Existing HomeLink Codes (Recommended)
Although optional, clearing any previously programmed codes from your Acura HomeLink system is a good practice, especially if you are programming a new garage door opener or have purchased a used vehicle.
To clear existing codes:
- Press and hold the two outer buttons of the HomeLink transceiver simultaneously.
- Keep holding them until the red indicator light starts flashing rapidly. This should take approximately 20 seconds.
- Once the indicator light flashes rapidly, release both buttons. This indicates that the memory is cleared.
-
Program HomeLink with Your Remote Transmitter
Now it’s time to teach your Acura HomeLink to recognize your garage door opener’s signal.
- Hold the remote transmitter about 1-3 inches (3-8 cm) away from the HomeLink button you wish to program in your Acura.
- Simultaneously press and hold the button on your garage door opener remote transmitter and one of the three HomeLink buttons in your Acura.
- Observe the indicator light on the HomeLink system. Initially, it will blink slowly (on/off about once per second) for the first 5-10 seconds.
- After a short period, the indicator light should start blinking rapidly (3-4 times per second).
- Once the red indicator light begins to blink rapidly, release both buttons. This indicates that the HomeLink system has successfully learned the frequency signal.
Troubleshooting Tip: If the HomeLink LED in your car continues to blink slowly and never transitions to a rapid blink, even after holding the buttons for an extended time, it’s highly likely that the battery in your garage door remote transmitter is weak or depleted. Even if the remote still operates your garage door, the signal strength might be insufficient for the Acura HomeLink to learn. Replace the battery in your remote transmitter and repeat this step.
-
Test the Programmed HomeLink Button
After completing step 5, press the HomeLink button you just programmed and hold it for about a second. Check if your garage door opens.
-
If the garage door opens, congratulations! You are finished with the programming process for a standard garage door opener.
-
If the garage door does not open, it’s likely that your garage door opener utilizes a rolling code system. Proceed to the next step. It’s important to complete steps 1-6 even if you know you have a rolling code system.

Rolling Code Garage Door Opener – Training the “Learn” Button
Rolling code garage door openers are designed for enhanced security. They change the security code each time the remote is used, preventing unauthorized access. To program HomeLink with a rolling code opener, you need to synchronize it with the “learn” or “training” button on your garage door opener motor unit.
- Locate the “training” or “learn” button on your garage door opener motor unit (the same button you located in Step 1).
- Press and release the “training” button on the garage door opener unit. A small LED indicator light near the button will usually illuminate, indicating it’s in learning mode. You typically have about 30 seconds to complete the next step.
-
Finalize HomeLink Programming with Rolling Code
- Within 30 seconds of pressing the “training” button on your garage door opener, return to your Acura and press and hold the programmed HomeLink button for 2-3 seconds.
- Watch for the garage door opener lights to flash or hear a click from the opener unit. This indicates that the HomeLink button is now linked to your rolling code garage door opener. You may need to repeat this press and hold cycle up to 3 times, depending on your opener model.
-
Test the HomeLink Button Again
Finally, press the programmed HomeLink button and hold it for a second to test if the garage door opens and closes correctly. The HomeLink indicator light will blink rapidly while you are holding the button.
If your garage door now operates with the HomeLink button, the programming is complete!
Important Note on Programming Multiple HomeLink Buttons: While it might seem convenient to program all three HomeLink buttons at once, especially if you have multiple garage doors or gates, be cautious if you have a rolling code garage door opener. Some rolling code systems have a limit on the number of remotes or devices that can be linked to them. Attempting to program all three HomeLink buttons in your Acura might potentially cause issues with other existing remotes or keypads linked to your garage door opener. It’s generally recommended to program only the HomeLink buttons you intend to use immediately to avoid potential conflicts.
By following these steps, you should be able to successfully program your Acura HomeLink system to control your garage door opener, adding convenience and seamless integration to your Acura driving experience.
