This video provides the step-by-step process to program a Guardian keypad to a Guardian garage door operator.

NOTE: Do not obstruct the photo-eye beam while in LEARN mode. Breaking the beam prior to programming may cause a fault in the LEARN process.

    I didn't see an answer to Cindy's question. I have the same issue. Thanks for any advise.

    The operator will learn 20 coces.  Programming another keypad code does not erase the prior code.  Codes are stored in the non-volitile memory in the powerhead.  Press the LEARN button for about 7 seconds to erase all stored codes then reprogram the keypad and all remotes.

    The keypad is simple enough to program. But my issue is that it will work regardless of whether a code is entered or not. Just pressing enter works. This not ok, because it offers zero security. Is this how the keypad is set up to really work? If so, I’ll be returning it. If not, how do I fix the problem.

    The keypad has an "emergency open/close" function.  If the keypad is used to open or close the door, for 30 seconds after activation, the "ENTER" button functions similar to a push button control.  This allows the homeowner to reverse travel without entering the code in case a possible obstruction is sensed or the homeowner wants to re-eneter the garage.  After the 30 seconds, the keypad code must be used to activate the opener.

    Hi Judy,

    The flashes indicate that a valid code was not received.

    If the keypd is a universal keypad (Clicker), it will not program to a Guardain operator.  The Clicker does not contain the Guardian code.

    To which model garage door opener are you programming the keypad?  If the garage door opener is a model 315, 415, 425 or 428, after pressing the LEARN button on the motorhead, do not break the photo-eye beam.  Breaking the beam will take the opener out of learn mode.

    If these tips do not help, please call 424-272-6998 for troubleshooting help.

    Going through the steps to set up after Lease, coding in the #'s, push Enter. After a few minutes I get 4 light flashes and the code does not work. Is there another step?

    Hi Maureen,

    There are 20 memory registers available so there should not be a problem.  If the LEARN button is pressed for over 5 seconds, all learned codes will be erased.  Do not press and hold the LEARN button during the entire cycle of programming. 

    Press and release the LEARN button.  The opener will be in learn mode for the next 30 seconds.  The operator will beep or flash the courtesy light (depending on model) to signal that the code has been learned.  Repeat for each remote and keypad.


    If you have further issues, please call Guardian tech service at 424-272-6998 for troubleshooting help..

    When we programmed the keypad the car portable models unlearned. When we reprogrammed the remotes, the key pad unlearned. How can we get all three to work at same time?

    Hi Lorenzo,

    1. Please check the keypad batteries.  Replace if necessary.

    2. When programming the new keypad code to the operator, after placing the operator into LEARN mode, DO NOT break the beam of the photo-eyes.  Breaking the beam will take the operator out of LEARN mode and the new code cannot be learned.

    Hello, I just reset the Guardian 415 to default and the keypad won't accept the code I want to use. I just moved into this house and want to secure it by removing all old owner access.

    The WKCC will work with the Lynx 455.  Try to program the keypad near the operator head before hanging it on the wall.  One keypad, using a different 2 to 6 digit code, can be programmed to each opener.

    Hi Tony,

    Please call tech service at 424-272-6998.  Have the garage door opener model number, serial number (located on the top of the opener just above the control buttons) and model number of the keypad that you are trying to program.

    I just bought a guardian keypad remote and although the lights blink and turn off after hitting the enter key, the door won't accept the keypad to load.

    The keypad blinks as it times out, so the batteries appear to be fine.

    Press the LEARN button on the operator, within 30 seconds enter your code then press ENTER.  If nothing happens, press the ENTER key again to resend the code.  If this does not work, please call tech service 1-424-272-6998.

    After entering your code, pressing the ENTER button will send your code to the opener.  For the next 30 seconds, the ENTER button acts as an emergency push button, allowing the user to change direction of the door quickly without the need to enter the code. 

    The keypad is functioning normally.

    Just purchased the Guardian wireless keypad model 303KP. We are having trouble getting the keypad to work. We are able to program in our new code but the keypad opens the door also by just pressing the ENTER button (not having entered a code at all). Cannot seem to fix this issue. Any recommendations or is the unit defective?

    The Guardian garage door opener receiver can store 20 remote control or keypad codes.  To erase the original keypad code, all codes stored in the receiver must be erased first.  Press & kold the "LEARN" button on the operator motor head for about 7 seconds until a beep is heard or courtesy light flashes.  Then re-program your keypad's new code and any hand held remote controls that were programmed previously.
