To reprogram your HomeLink system to control your garage door opener, you'll need your garage door opener's remote control. The process usually involves these steps:
1. Locate the HomeLink buttons: These are usually three buttons on the overhead console.
2. Identify your HomeLink's learning mode: This is crucial. The exact method to enter learning mode varies slightly depending on the HomeLink system version installed in your specific DTS. Common methods include:
* Press and hold two HomeLink buttons simultaneously until the indicator light(s) on the buttons blink or remain illuminated. Hold for 15-20 seconds, sometimes longer.
* Press and hold one HomeLink button for a specific time (consult your Cadillac owner's manual for the exact procedure for your vehicle; the manual is the best source). The light should blink or stay on.
3. Program the HomeLink button: Once the learning mode is activated (you'll usually see an indicator light change behavior), follow these steps:
* Position yourself close to the garage door opener. This is important for signal strength.
* Hold your garage door opener's remote close to the HomeLink buttons.
* Press and hold the button on your garage door opener's remote control.
* While holding the garage door opener's remote button, press and release the HomeLink button you want to program. Some systems require you to press and *hold* the HomeLink button until the garage door opens and closes.
* Release the button on your garage door opener's remote control.
* The HomeLink indicator light should change to confirm successful programming. If not, repeat the process.
4. Test the HomeLink system: Press the HomeLink button you programmed to see if your garage door opens and closes successfully. If not, repeat the process, ensuring you're following your Cadillac owner's manual instructions precisely.
Crucially, consult your 2007 Cadillac DTS owner's manual. This manual will have the exact and most reliable instructions for programming the HomeLink system in your specific car. The steps outlined above are general and might vary slightly. The manual will also likely illustrate the location of the HomeLink system and provide troubleshooting tips.
If you've tried these steps and still can't program the HomeLink system, there might be a problem with the HomeLink system itself or your garage door opener's remote. You might consider contacting a Cadillac dealer or an automotive electronics specialist for assistance.
