How to Change the Code on a Garage Door Keypad

April 12, 2024

Your garage door opener is incredibly convenient. But remember, it's also a way into your home! Enhance your security by regularly changing your keypad PIN code. The process is usually simple, though it may vary slightly depending on the brand of your garage door opener. For example, Chamberlain has a guide to change a Keyless PIN on multiple Liftmaster models. It's always best to refer to your user manual for the most accurate instructions.

Reasons to Change Your Garage Door Code

Garage door codes offer easy and secure access to your garage, with the convenience of opening the door via a keypad or remote instead of manually. These codes not only make access more efficient but also enhance security by ensuring only authorized individuals can enter.

However, circumstances may arise where changing or resetting your garage door code is necessary for continued security. Here are some key reasons to change your garage door keypad code:

  • Forgetting the Code: If you can't remember your code or repeatedly enter it wrong, you'll need to reset it to regain access.
  • Lost or Stolen Remote: If your garage door remote goes missing, changing the code immediately prevents unauthorized access.
  • Compromised Security: If you think someone might know your code, change it without delay to maintain control.
  • Regular Maintenance: Periodically changing the garage door opener code enhances home security.
  • New Home: When you move into a new house, change the garage door code to ensure previous owners or residents cannot gain access to your garage.
  • Specific Access: If you've given your code to anyone temporarily (a delivery person, contractor, etc.), change it afterward to ensure continued security.

Luckily, changing a garage door code can be done by yourself without special skills or equipment. However, if you ever need help or have any concerns, don't hesitate to reach out to our team of experts. We're here to support you!

Step 1: Locate the Learn Button

Locate the Learn Button

The first step in the code-changing process is locating the 'Learn' button on your garage door opener motor unit. This button is typically small and colored (often yellow, orange, purple, or green). You'll usually find it on the back or side of the opener unit, located inside your garage. If you're using Chamberlain you can find instructions on their website.

The first step to changing your code is finding the ‘Learn’ button on your garage door opener's motor unit. This button is usually small, colored (often yellow, orange, purple, or green), and located on the back or side of the unit inside your garage. Be sure to check your owner's manual or the manufacturer's website (like Chamberlain's) if you're having trouble finding it.

Step 2: Clear Existing Keypad Memory

Before you can set a new code, you'll need to clear the garage door opener's memory of the old one. This process usually involves the following steps:

  1. Enter your Existing Code: Begin by entering your current, working code into the keypad.
  2. Press and Hold: Find the designated button on your keypad – your owner's manual will have this info. Press and hold this button for a few seconds. You'll know the old code is cleared when the opener's lights blink or you hear a beep.

Step 3: Entering the New Code on Your Keypad

Now you're ready to enter your new garage door opener code:

  1. Choose a PIN Code: Select a 4-digit code that is easy for you to remember but difficult for others to guess. Avoid obvious combinations like birthdays or simple sequences (e.g., 1234).
  2. Enter on Keypad: Type your chosen code into the keypad.
  3. Press Enter: Hit the "Enter" button or a similar button on your keypad to save the new code.

Step 4: Press the Learn Button on the Opener Unit

Press the Learn Button on the Opener Unit

With your new code entered on the keypad, it's time to link it to the garage door opener itself. Here's how:

  1. Press the Learn Button: Press the 'Learn' button on your garage door opener's motor unit. The light on the opener will typically blink.
  2. Time Window: You usually have about 30 seconds to complete the next step (refer to your manual to be sure).
  3. Enter Code Again: Type your new code into the keypad and press "Enter". The opener's light should flash or you might hear a click – this means your new code is saved!

Step 5: Test Your New Code

Make sure your new code works! Enter it into the keypad and press "Enter". Your garage door should open or close as expected.

If the new code doesn't work:

  • Make sure you entered the new code correctly on your keypad.
  • Ensure the batteries in the keypad are fresh.
  • Refer to your garage door opener's user manual for specific troubleshooting instructions.

Setting Up a Temporary Code for Your Garage Door

Planning a vacation and need someone to check on your house while you're gone?  A temporary garage door code is a great way to give them access without compromising security.  The code will expire after a certain amount of time or number of uses, so you don't have to worry once your trip is over.

Compatibility: Ensure your garage door opener supports temporary PINs, typically available with Security+ or Security+ 2.0 models. This feature is not available for garage door openers using external receivers or those with a green learn button.

According to Chamberlain's official website, the following Models Support Temporary PIN Setup:

Setting Up a Temporary Code for Your Garage Door

For a Specific Amount of Hours:

  1. Enter your regular 4-digit PIN and press the * key until the opener light blinks, indicating it's in programming mode.
  2. Input the temporary PIN you wish to use and press the enter key. Watch for the opener light to flash four times as confirmation.
  3. Decide how long you want the temporary code to work (in hours) and enter that number on the keypad. Press * to save your settings.

For a Set Number of Uses:

  1. Input your usual PIN code for the garage door opener and then press the * key until the opener light blinks three times (this means it's in programming mode).
  2. Enter the desired temporary PIN, press the enter key, and wait for the opener light to blink four times.
  3. Determine the usage limit for the temporary PIN (anywhere from 1-255 uses), and enter that number. Press # to save your settings.


Taking a few minutes to change your garage door opener keypad code is a smart investment in protecting your home.  By following these steps and checking your owner's manual, you can easily boost your security and keep your garage safe.

For best results, make code changes part of your regular home maintenance routine –  think of it like changing your passwords or the batteries in your smoke detectors.  And remember, if you ever have any questions or need assistance, our team of experts at Safety Garage Door is always here to help!
