2.3 Programming the Keypad

The Chamberlain myQ Wireless Garage Door Keypad is compatible with Chamberlain, LiftMaster, and most Craftsman garage door openers manufactured after 1997 that feature safety sensors. Refer to the 'Product Set Up Insert' included in your package for the most accurate and detailed programming instructions specific to your garage door opener's learn button color.

A general programming sequence often involves:

  1. Locate the 'Learn' button on your garage door opener motor head. Note its color (e.g., red, orange, purple, yellow, green, white).
  2. On the keypad, press and hold the '0' and '3' buttons simultaneously until the keypad's backlight becomes solid.
  3. Enter your desired 4-digit Personal Identification Number (PIN).
  4. Press the 'Home' button (the button with the house icon) twice.
  5. Immediately press and release the 'Learn' button on your garage door opener motor head.
  6. Within 30 seconds, press the 'Home' button on the keypad repeatedly until the garage door opener activates (lights flash or door moves). This may require several presses.
  7. Test your new PIN by entering it and pressing the 'Home' button. The garage door should operate.

Note: If programming difficulties arise, consult the specific instructions provided with your keypad or visit the Chamberlain support website. Some users have reported success by continuously pressing the 'Home' button after the initial programming steps until the opener responds.

3.1 Opening and Closing the Garage Door

To operate your garage door using the keypad:

  1. Enter your 4-digit personal PIN.
  2. Press the 'Home' button (house icon).
  3. The garage door will begin to open or close.

3.2 Creating Temporary PINs

The keypad allows you to create temporary PINs for guests, dog walkers, or service personnel, providing limited access without sharing your primary PIN. Refer to the 'Product Set Up Insert' for detailed instructions on setting and managing temporary PINs.

3.3 One-Touch Close Function

For quick exits, the keypad features a one-touch close function. After entering your PIN and pressing the 'Home' button to open the door, the keypad's backlight will flash for approximately 10-15 seconds. During this grace period, you can press the 'Home' button again to close the door without re-entering your PIN. If the backlight is no longer flashing, you will need to re-enter your PIN to operate the door.

When the keypad's backlight dims or the keypad becomes unresponsive, it is time to replace the 9V battery. Follow the battery installation steps in Section 2.1.

4.2 Cleaning

To clean the keypad, use a soft, damp cloth. Avoid abrasive cleaners or solvents, as these can damage the keypad's surface or internal components. Ensure the keypad is dry before use.

5. Troubleshooting

If you encounter issues with your Chamberlain myQ Wireless Garage Door Keypad, consider the following common troubleshooting steps:

  • Keypad Not Responding: Check the battery. Replace the 9V battery if it is low or depleted.
  • Programming Failure: Ensure you are following the specific programming steps for your garage door opener's learn button color as outlined in the 'Product Set Up Insert'. Verify that the learn button on your opener was pressed correctly and that you are pressing the keypad's 'Home' button repeatedly within the specified timeframe after pressing the opener's learn button.
  • Intermittent Operation: This could indicate a low battery or interference. Try replacing the battery. Ensure there are no obstructions between the keypad and the garage door opener.
  • One-Touch Close Not Working: Remember that the one-touch close function is only active for a short period (10-15 seconds) after the door has been opened using the keypad. If the backlight is no longer flashing, you must re-enter your PIN.
  • Range Issues: Ensure the keypad is mounted within effective range of your garage door opener. Repositioning the keypad slightly may help.

For persistent issues, refer to the detailed troubleshooting guide in your product's setup insert or contact Chamberlain customer support.
