2. Press and release the PURPLE learn button on the motor unit of your garage door opener. A yellow light will light up next to the learn button.
3. Using the keypad within 30 seconds enter a 4-digit number of your choice and press and hold down on the ENTER key.
4. Release the Enter key when the garage door opener motor unit lights blink. If bulbs are not installed, you should hear 2 clicks after 4 seconds.
5. Enter your 4-digit code to test the keypad. You are now done.
