CPTK13 LiftMaster Passport Key Ring Remote

'CPTK13 LiftMaster® Passport Single-Button Pocket Remote'
The CPTK13 one-button keychain remote serves as a suitable substitute for garage door openers that utilize a purple learn button located on the motor unit's powerhead, which is mounted to the garage ceiling. The order comes with a compatible remote, a key ring, a pre-installed battery, and instructions for programming. We dispatch orders on the next business day and offer a 30-day return policy.
Compatible Remote Programming Instructions:
Locate the PURPLE Learn button on your garage door opener power head (it will be a square PURPLE button on the end of the motor unit where the antenna wire is located.) You may have to remove the light lens cover on some models.
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.
Immediately press and release one push button on the new compatible remote control (you should hear a click in the motor unit and your light bulb(s) may flash).
Press the remote button again you just programmed to test it. You are now done.
Repeat steps 2 through 4 for each additional push button. *
* Each remote button is used for PURPLE learn button opener programming only.
