Programming your Acura’s HomeLink system to operate your garage door opener offers unparalleled convenience. No more fumbling for a separate remote – with HomeLink, opening and closing your garage door is as simple as pressing a button on your rearview mirror. This guide provides a comprehensive, step-by-step walkthrough to successfully program your Acura HomeLink system, ensuring a smooth and efficient setup process.
Step-by-Step Guide to Program Your HomeLink System
Follow these instructions carefully to link your garage door opener to your Acura HomeLink. Before you begin, ensure you have a working garage door remote and can access your garage door opener unit.
Step 1: Preparation and Positioning
Begin by parking your Acura within close proximity to your garage door. For ease of access and safety during testing, parking inside your garage is ideal, provided there’s enough clearance. Ensure the area around the garage door is clear, as it will open and close during the programming and testing phases. You will also need a step ladder to reach the garage door opener unit safely. Locate the “training” or “learn” button on your garage door opener motor unit. This button is often found on the back or side of the unit, sometimes behind a light cover for protection.

Step 2: Retrieve Your Garage Door Remote Transmitter
You’ll need a working remote transmitter that originally came with your garage door opener. This remote is usually a small, handheld device with one to three buttons, often equipped with a visor clip. If you cannot locate your original remote, you will need to purchase a compatible remote transmitter for your garage door opener. You’ll first need to link this new remote to your garage door opener.
Linking a New Remote Transmitter (if necessary):
- Press and release the training button on your garage door opener unit.
- Within 30 seconds, press and hold the button on the new remote transmitter.
- Wait for the garage door opener light to blink. This indicates successful linking.
- Press the button on the new transmitter to confirm it opens the garage door.

Step 3: 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. If your Acura uses a key-based ignition, turn the ignition key to the ON position.
Step 4: Clear Existing HomeLink Codes (Recommended)
To ensure a clean programming process, it’s advisable to clear any previously programmed codes from your HomeLink system. Press and hold the two outer buttons on your Acura’s HomeLink transceiver (usually located on the rearview mirror or visor). Hold them until the red indicator light starts flashing rapidly, which should take approximately 20 seconds. Release the buttons once the rapid flashing begins. This step resets the HomeLink system.
Step 5: Program HomeLink with Your Remote Transmitter
Position the remote transmitter 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 remote and one of the three HomeLink buttons in your car. Observe the indicator light on the HomeLink system. It will initially blink slowly (about once per second) for the first 5-10 seconds, then it should transition to a rapid blink (3-4 times per second). Once the indicator light blinks rapidly, release both buttons.
Troubleshooting Tip: If the HomeLink LED continues to blink slowly, and doesn’t transition to a rapid blink even after holding the buttons for an extended period, the battery in your garage door remote transmitter might be weak. While the remote might still be able to open your garage door, the signal strength may be insufficient for the Acura HomeLink system to learn. Try replacing the battery in your remote and repeat this step.
Step 6: Test the HomeLink Connection
Press and release the HomeLink button you just programmed and hold it for about a second. Observe your garage door. If the garage door opens, congratulations! You have successfully programmed your HomeLink system. If the door does not open, proceed to the next step, as your garage door opener likely uses a rolling code. It’s important to complete all previous steps even if you know you have a rolling code system.
Step 7: Rolling Code Programming (If Necessary)
For garage door openers with rolling code technology, an additional “training” step is required.
- Press and release the training or “learn” button on your garage door opener motor unit again. A small indicator light, often an LED, will illuminate near the training button, indicating it’s in learning mode. You typically have about 30 seconds to complete the next step after pressing this button.

- Within 30 seconds of pressing the training button on the garage door opener, return to your Acura and press and hold the programmed HomeLink button for 2-3 seconds. You should see the garage door opener lights blink, or hear the unit click, indicating that the HomeLink button is now linked to your garage door opener’s rolling code system.
Step 8: Final Test
Press and release the programmed HomeLink button again, holding it for about a second. The HomeLink indicator light will blink rapidly while you hold the button. Your garage door should now open and close reliably with your Acura HomeLink system.
Important Considerations
While you might be tempted to program all three HomeLink buttons at once, especially if you have multiple garage doors or gates, be cautious, particularly with rolling code systems. Some garage door openers have a limit on the number of remotes or HomeLink buttons that can be linked. Over-programming can sometimes cause issues, such as previously programmed remotes or keypads ceasing to function. If you experience issues after programming multiple buttons, try programming only the button you need for your primary garage door opener first.
By following these steps, you should be able to easily program your Acura HomeLink system to control your garage door opener, adding a touch of modern convenience to your daily driving experience.
