Reset Your Keypad Code in Three Steps

To reset your LiftMaster garage door keypad code, you need to enter the current master code, press the pound key (#), then enter your new four-digit code twice. The whole process takes about two minutes and requires you to be standing at the keypad itself—you cannot do this remotely. If you have forgotten your current master code, you will need to use the reset button inside your garage door opener unit instead.

The exact steps depend on whether your keypad is a wireless model or a wired model, but both follow the same basic sequence. Most LiftMaster keypads will beep or flash a light to confirm each step, so you will know if you have entered the code correctly.

Key Takeaways

  • You must stand at the keypad and enter your current master code before you can change it to a new one.
  • The new code must be four digits long and different from any code already in use on that keypad.
  • If you have forgotten your master code entirely, you will need to press the reset button on the garage door opener motor unit itself, which erases all codes.
  • After resetting, test your new code from outside the garage to confirm it opens the door before you leave the area.
  • Some LiftMaster models require you to hold down the pound key (#) for three seconds rather than just pressing it once.

Gather Your Current Master Code and New Code

Before you walk to the keypad, decide on your new four-digit code. Choose something you can remember but that is not obvious—avoid birthdays, house numbers, or repeating digits like 1111. Write it down somewhere safe, separate from where you keep your garage door opener remote.

You will also need your current master code. This is the code you use to open the door now. If you share the garage with others, ask them what code they use, because the master code is the same for everyone. If nobody remembers it, skip to the section on using the reset button on the motor unit.

Steps to Reset a Wired Keypad

Walk to your keypad and stand close enough to see the buttons clearly. Press the master code you currently use, then when ready press the pound key (#) once. You should hear a beep or see a light flash—this tells you the keypad is ready to accept a new code.

Enter your new four-digit code, then press the pound key (#) again. Enter the same four-digit code a second time and press pound (#) one more time. The keypad should beep twice or flash twice to confirm the code has been saved. If it beeps once or does not beep at all, the code did not save—start over from the beginning.

Walk back outside and test the new code from your car or driveway. Press the new code followed by the pound key (#). The garage door should open. If it does not, return to the keypad and try the reset process again, making sure you pressed pound (#) at each step.

Steps to Reset a Wireless Keypad

Wireless LiftMaster keypads work the same way as wired ones, but they communicate with the garage door opener through a radio signal rather than a cable. Stand within 30 feet of the garage door opener unit so the signal reaches it.

Enter your current master code, then hold down the pound key (#) for three seconds—not just one press. You should see the light on the keypad blink or hear a beep. Enter your new four-digit code and hold pound (#) for three seconds again. Enter the code a second time and hold pound (#) for three seconds one final time. The keypad should flash or beep twice to confirm.

Step away from the garage and test the new code from outside. If the door does not open, move closer to the garage door opener unit and try the reset again. Wireless keypads sometimes have trouble communicating if they are too far away or if there are metal objects between the keypad and the opener.

What to Do If You Forgot Your Master Code

If nobody remembers the current master code, you will need to reset the entire keypad by pressing the reset button on the garage door opener motor unit itself. This button is usually red or yellow and is located on the side or back of the motor unit, near the power cord. You may need to unplug the unit or turn off the breaker first for safety.

Press and hold the reset button for about 10 seconds until you hear a beep or see a light flash. This erases all codes from the keypad. You will then need to reprogram the keypad from scratch by entering a new master code, which usually involves pressing a button on the motor unit and then entering your code at the keypad. Consult your LiftMaster manual or the label on the motor unit for the exact steps, because the process varies by model.

After you reset the motor unit, all remotes and keypads will stop working until you reprogram them. This is why resetting should be your last option—use it only when you have truly lost access to all codes.

Common Mistakes That Prevent Code Changes

The most common mistake is forgetting to press the pound key (#) at each step. If you enter your code and then just start typing the new code without pressing pound (#), the keypad will not understand that you are trying to change the code. It will think you are trying to open the door with a very long code, which will fail.

Another mistake is entering a code that is too short or too long. LiftMaster codes must be exactly four digits. If you enter three digits or five digits, the code will not save. Some keypads will beep to tell you the code is the wrong length, but others will just fail silently.

A third mistake is testing the new code too soon, before you have finished the reset process. If you walk away after entering the code once, you may think it worked when it actually did not. Always complete all the steps, including pressing pound (#) at the very end, before you test the door.

Frequently Asked Questions

Can I reset the keypad code from my phone or remote?

No. You must stand at the physical keypad to change the code. LiftMaster keypads do not have a remote reset option for security reasons. If you are away from home, you will need to ask someone else to reset it for you, or wait until you return.

What if the keypad beeps once instead of twice at the end?

A single beep usually means the code did not save. This often happens if you did not press the pound key (#) at the right moment, or if you entered a code that was too short or too long. Go back to the keypad and start the reset process over, paying close attention to each beep.

Can I have multiple master codes on one keypad?

Most LiftMaster keypads have only one master code, but some models allow you to program additional user codes. Check your keypad manual to see if your model supports multiple codes. If it does, the process for adding a second code is different from resetting the master code.

Do I need to reprogram my remote after I reset the keypad code?

No. Your garage door remote and your keypad code are separate. Changing the keypad code does not affect your remote. The remote will continue to work as long as it is paired with your garage door opener motor unit.

What if my keypad is not beeping or flashing after I press the buttons?

Check that the keypad has fresh batteries if it is wireless, or that the wired keypad is plugged in. If the batteries are dead or the power is off, the keypad will not respond to button presses. Replace the batteries or restore power, then try the reset process again.
