How to Pair Your Keypad with Your Garage Door Opener
The pairing process for your Chamberlain B3000, C2405, B4310, and B4603T models is identical because they all use the Security+ 2.0 (yellow learn button) technology. Follow these simple steps:
General Pairing Process for Security+ 2.0 (Yellow Learn Button) Models
- Locate the Learn Button: On the back or side panel of your garage door opener motor head, find the yellow “Learn” button.
- Press the Learn Button: Press and immediately release the yellow Learn button. The LED indicator light next to the button will glow steadily for 30 seconds, indicating it’s ready to receive a signal.
- Enter Your Personal Identification Number (PIN): Within 30 seconds of pressing the learn button, go to your new keypad. Enter your desired 4-digit (or more) personal identification number (PIN).
- Press the Enter Button: After entering your PIN, press and hold the “Enter” button (or the specific programming button, often a large “Enter” or “#” button) on the keypad.
- Release the Button: Release the “Enter” button when the garage door opener lights flash or you hear two clicks. This signifies that the keypad has successfully been programmed.
- Test the Keypad: Enter your newly programmed PIN on the keypad and press “Enter.” Your garage door should activate, confirming successful pairing.
Specific Notes for Models (B3000, C2405, B4310, B4603T)
