Here's how to typically program a universal garage door opener remote:
1. Locate your garage door opener's "learn" button: This is usually a small button on the garage door opener motor unit itself. Consult your garage door opener's manual if you can't find it.
2. Get your car's remote ready: Your Chevy Impala's universal garage door opener remote likely has a button to press and hold to initiate programming. The exact process is specific to the *brand* of the garage door opener remote you have (some use a single button, others might have a button combination). Check your remote's instructions. They will usually indicate a sequence involving holding a button down until an LED light blinks a certain way, etc.
3. Program the remote:
* Press and hold the "learn" button on your garage door opener unit. You'll often hear a click or beep. Release the button.
* Now, quickly press and hold the button on your *car's* garage door opener remote according to its instructions. You should see an indicator light on the remote change.
* The garage door opener unit might beep or flash to signal that it has learned the code from the remote.
* Test the remote.
Important Considerations:
* Find your instructions: The most reliable instructions are those that came with your specific car's garage door opener remote. Different brands have different methods.
* Multiple remotes: You might have more than one button on the car's garage door opener. Each button is likely programmable independently for multiple garage doors.
* Battery: Ensure the battery in your car's garage door opener remote is fresh. A weak battery can interfere with programming.
* Distance: Be close to the garage door opener motor unit while programming.
If you're having trouble, searching online for instructions specific to the *brand and model* of your universal garage door opener remote will likely yield the best results. The remote itself is what needs programming, not the car's system.
