Opener

The garage door opener in the CT5 is a Gentex HomeLink HL5. HomeLink HL5 supports two-way communications. When paired with a compatible two-way garage door opener (MyQ and AssureLink models) the Homelink is able to indicate the last known status of the door. It's not clear that the HomeLink in the CT5 uses this feature.

Homelink Programming

Here's my take on the Homelink programming process:

Erase All Existing Programming (Optional)
To reset the Homelink to a completely unprogrammed state, press and hold the two outside buttons until the LED starts flashing or until 20 seconds has passed.
Reprogramming a Button
Press the Homelink button and observe the LED. If it flashes slowly, the button is unprogrammed; release the button and proceed to the next step.
If the Homelink LED says on solid or flashes rapidly when you press the button it is already programmed. Continue pressing the button until the LED starts flashing slowly (which indicates learning mode). Continue pressing and proceed to the next step.
Per-Button Programming
With the garage door opener remote 1 to 3 inches away from the Homelink, press and hold the desired Homelink button and the opener remote button at the same time. The garage door will open or close and the Homelink LED will flash slowly and then rapidly as it learns from the opener remote. Once the LED flashes rapidly, release both buttons.
Now press the Homelink button and observe the LED. If it stays on while pressed, you have a legacy garage door opener and it should open or close. If it flashes rapidly, your opener uses a rolling code system (congratulations) and you need to proceed to the next step to program your garage door opener.
Rolling Code System Programming
At this point you have taught the Homelink what kind of rolling code system your garage door opener uses. Now you need to teach your opener to recognize your Homelink.
Your garage door opener should have a "smart" button. Press it until you see some indication that the opener has entered learn mode. Then go back and press the Homelink button for two seconds and release for one second. Repeat until the garage door opens or closes. This process can take two or three presses. If you have trouble, refer to your garage door openers manual. Assuming you programmed the Homelink button correctly in the previous steps, the Homelink is just another opener remote as far as your garage door opener is concerned.
Note that you only have 30 seconds to complete the garage door opener learning process; if you take too long, start this step again.
