Setup and Installation
The Chamberlain 940EV-P2 is designed for hassle-free wireless installation and programming, typically completed within minutes. Ensure your garage door opener has a working light bulb, as it serves as a programming indicator.
Before You Begin
- Verify compatibility: Works with Chamberlain, LiftMaster, and Craftsman garage door openers from 1993 to present (openers with safety sensors). Not compatible with Craftsman Series 100 or 200.
- Install the included CR123A battery into the keypad.
- Ensure the garage door opener's light bulb is functional.
Programming the Keypad
Follow these steps to program your keypad to your garage door opener:
- Locate the "Learn" button on your garage door opener. The color of this button (yellow, purple, red/orange, green) indicates the frequency and programming method.
- Press and release the "Learn" button on your garage door opener. The indicator light will illuminate.
- Within 30 seconds, enter your desired 4-digit Personal Identification Number (PIN) on the keypad.
- Press and hold the "ENTER" button on the keypad.
- Release the "ENTER" button when the garage door opener lights flash or two clicks are heard. This indicates successful programming.
- Test the keypad by entering your PIN and pressing "ENTER". The garage door should activate.
Tip: For optimal programming success, position the keypad very close to the garage door opener unit during the programming steps. You may need a ladder if the opener is installed high.

Operating the Keypad
The keypad provides convenient access to your garage without a remote control or key.
Opening/Closing the Garage Door
- To open or close the garage door, enter your 4-digit PIN.
- Press the "ENTER" button. The garage door will activate.
- The keypad features a "one-button close" option. After opening the door with your PIN, you can simply press the "ENTER" button again to close it without re-entering the PIN.
Note: If the keypad has been inactive for a period, the first key press may serve to "wake up" the unit. In such cases, the first digit of your PIN might not register. It is recommended to press any key (e.g., "ENTER") to activate the keypad before entering your PIN, or simply re-enter your PIN if the door does not respond on the first attempt.
Programming a Temporary PIN
A temporary PIN can be programmed for deliveries or guests, providing limited access without compromising your primary PIN.
- Enter your primary 4-digit PIN.
- Press and hold the "*" button until the garage door opener lights flash.
- Enter the desired temporary 4-digit PIN.
- Press the "ENTER" button.
- The temporary PIN is now active. It will typically work for a single use or a set number of hours, depending on your opener model. Refer to your garage door opener's manual for specific temporary PIN duration settings.
