QUESTION:
I just moved into a home that has an Overhead Door Legacy 496 garage door opener and I need to change the garage door remote code. Can you help?
ANSWER:
Following are instructions provided by Overhead Door Corporation. They cover Overhead Door Legacy 496 and 696 Remote Code Programming, with a little clarification.
NOTE: When programming your garage door remote, you need to keep the remote at least 24 inches away from the antenna on the power head (the motor unit that mounts to the ceiling). The antenna is a small wire that should be hanging down from the power head.
One Button Garage Door Remote Programming:
1. Look on the back panel of the power head (motor mounted to the ceiling). In the lower, right hand corner you will find a “learn code” button and learn indicator light. See the image (below) and the red circle around the learn code button and the learn indicator light. 
2. Press and then release the “learn code” button. The LED learn indicator light should now be blinking about 2 times per second.
3. Press and then release the button on the garage door remote. The LED learn indicator light on the power head should stop blinking and stay solid on.
4. Press and then release the garage door remote button a second time. The LED learn indicator light on the power head should go out. The garage door remote should now be programmed.
Multi-Button Garage Door Remote Programming:
Follow the one button programming instructions above for each of the buttons on the multi-button remote. If you have more than one Overhead Door garage door opener, you can program each of the buttons independently to operate more than one opener.
