Here's how to typically use one:
1. Obtain a universal garage door opener: These are readily available at most auto parts stores, home improvement stores (like Home Depot or Lowe's), and online retailers.
2. Identify your car's power outlet: Locate the 12V power outlet in your Cadillac DTS.
3. Plug in the garage door opener: Insert the universal garage door opener into the car's power outlet.
4. Program the garage door opener: This process varies slightly depending on the brand of the opener. Consult the instructions that came with your specific universal garage door opener. Generally, it involves:
* Learning mode: Putting the garage door opener into "learn" or "programming" mode (usually by pressing and holding a button on the device).
* Garage door opener button: Pressing and holding the button on your existing garage door opener's remote control.
* Confirmation: The universal garage door opener should indicate when it's successfully learned the code (often with a light or sound).
5. Test the opener: Press the button on the universal garage door opener in your car to see if it opens and closes your garage door.
Important Note: If your garage door opener uses a newer rolling code technology, some universal garage door openers might not be compatible. If you encounter difficulties, try a different brand of universal garage door opener. Also, refer to the instructions provided with *your specific* universal garage door opener as the steps may vary slightly.
