How to Reset a LiftMaster Keypad (Step-by-Step Guide)

Wondering how to reset your LiftMaster garage door keypad? Whether you've moved into a new home, forgotten your code, or want to upgrade security after a contractor visit, the process takes about five minutes. In this guide, we'll show you how to reset a LiftMaster keypad on standard wireless models, the 878MAX, the myQ® Video Keypad, and Security+ 3.0 (L979) keypads, and how to remove old codes from the system and perform a full factory reset when you've forgotten everything.

If your keypad isn't responding at all, the buttons aren't lighting up or the door isn't reacting when you press Enter, that's a hardware issue, not a code issue. Start with our LiftMaster keypad troubleshooting guide before resetting.

Why You'd Reset Your LiftMaster Keypad

Your keypad is one of the most convenient ways to access your home, until something compromises it. Resetting your code is the simplest way to restore security in any of these situations:

• Moving into a new home - The previous owners (and anyone they shared the code with) may still know it, make sure to reset on day one.

• Forgotten or lost code - Easier to reset than to keep guessing and you can pick a PIN that's easier to remember.

• Tenants moving out - Don't rely on a goodbye to keep them out, change the code before the next move-in.

• Suspected compromise -  If you've seen anything unusual or someone you don't trust may have learned the code, reset immediately.

• After contractor or service visits - Cleaners, repair crews, dog walkers or anyone who's had temporary access. Even if they were trustworthy, the code may have been written down somewhere it shouldn't be.

A quick tip on choosing a new PIN: avoid birthdays, addresses, and obvious sequences (1234, 0000, 1111). Pick four digits that don't appear on any document a stranger could see.

How to Reset a LiftMaster Keypad (Standard Models)

To reset a LiftMaster keypad, press and release the Learn button on the motor unit, then enter your new 4-digit PIN on the keypad and hold the Enter button until the opener's lights flash. The whole process takes under two minutes once you can reach the opener.

Here's the step-by-step:

Step 1: Press the Learn button on the motor unit

Use a stepladder to reach the LiftMaster opener mounted to your garage ceiling. Find the Learn button on the back of the unit, usually near the antenna wire. Different LiftMaster models use different Learn-button colors like yellow, red, purple, orange or green, but they all behave the same way: a single press primes the unit for 30 seconds.

Important

Press and release the Learn button; do not hold it down. Holding the Learn button for 6+ seconds erases all stored codes and remote pairings. That's the full clear-memory function (covered later in this guide), not the simple reset.

Make sure no one nearby is using a remote while you press the Learn button, because otherwise their remote could accidentally pair with your opener during the 30-second window.

Step 2: Enter your new 4-digit PIN

Walk back to the keypad and enter the new 4-digit PIN you want to use. You have 30 seconds after pressing the Learn button to complete this step. If you take longer, the unit times out and you'll need to start over.

Step 3: Hold Enter (or # / 0 on universal keypads)

After entering your new PIN, press and hold the Enter button on the keypad until the opener's light blinks (or you hear two clicks). That confirms the new code is stored.

Keypad has no Enter button?

Some universal LiftMaster keypads use the # or 0 key in place of Enter. The 4-digit code-entry sequence is identical,  only the confirm key changes. Look up your keypad's model number for the exact key, or test by entering a known code and trying each candidate confirm key.

Test the new code by entering it on the keypad and pressing your confirm key. If the door responds, you're done. If not, repeat the process since most failures come from running past the 30-second window in Step 2.

How to Reset a LiftMaster 878MAX Keypad

The LiftMaster 878MAX is the most commonly-shipped wireless keypad with new LiftMaster openers, and it has a slightly different programming sequence than the standard Learn-button flow above. If your keypad has the 878MAX label visible on the front, follow these steps instead:

1. On the 878MAX keypad, press and hold the * and # keys together until the small light on the keypad blinks twice.

2. Enter your new 4-digit PIN.

3. Press the # key to confirm. The light will blink to confirm the new code is saved.

That's it, no Learn button required for the 878MAX itself. The 878MAX stores the code internally and sends the signal to your opener. If you've never paired the 878MAX to your opener at all, you'll still need to do the Learn-button step to introduce them; once paired, code changes happen entirely on the keypad.

Programming a LiftMaster Garage Door Keypad plus New myQ Video Keypad Review

How to Reset a myQ® Video Keypad (VKP1-LM) and Security+ 3.0 Keypads

Newer LiftMaster keypads, including the myQ® Video Keypad (VKP1-LM) and the Security+ 3.0 line (L979S, L979M, L979U) are managed through the myQ app rather than the Learn button. The reset process is fundamentally different from older keypads, so don't try to use the Learn-button method on these.

Resetting the myQ Video Keypad (VKP1-LM)

1. Open the myQ app on your phone.

2. Tap Settings then go to Devices.

3. Select your myQ Video Keypad from the device list.

4. Tap Reset Keypad, then confirm.

5. Set a new 4-digit PIN inside the app and save.

The new PIN is active immediately and that’s because the keypad is connected to the app, but you can also manage temporary guest codes from the same screen, this is very useful for cleaners, contractors, or short-term visitors.

Resetting Security+ 3.0 Keypads (L979S/M/U)

The L979 series uses Security+ 3.0 encryption and is paired and managed through the myQ app. To reset:

1. Open the myQ app.

2. Go to Settings then go to Devices, select your L979 keypad.

3. Tap Change PIN (or Reset Keypad for a full factory reset).

4. Enter your new 4-digit PIN and save.

Browse our full range of LiftMaster keypads to compare standard wireless, smart and Security+ 3.0 models if you're considering an upgrade. The myQ Video Keypad adds smartphone control and a built-in camera; the L979 series adds the strongest encryption LiftMaster offers.

How to Remove Old Codes After Setting a New PIN

Here's something that surprises a lot of LiftMaster owners: setting a new PIN does not automatically erase old codes from the opener. The opener can store multiple keypad codes simultaneously, and unless you explicitly clear them, the old code keeps working alongside the new one.

Why this matters

If you reset your code because a tenant moved out or you suspect someone has the old PIN, the simple new-PIN steps above don't lock them out. You need to fully clear the opener's memory and then reprogram everything.

To remove all old codes:

1. Reach the opener's motor unit with a stepladder.

2. Press and hold the Learn button until the LED indicator goes off, about 6 to 10 seconds. Don't release early.

3. That clears all stored keypad codes AND all paired remote controls.

4. Reprogram your new keypad code using the standard 3-step reset above.

5. Reprogram any remote controls you want to keep using by pressing Learn (a single quick press this time), then pressing the remote button you want to assign.

The trade-off: clearing all codes also unpairs every remote in your household. If you have multiple remotes, garage door openers in cars, or wall stations, you'll need to re-pair each one. For most households, that's 5–15 minutes of extra setup, but it's the only way to be certain the old PIN no longer works.

Full Factory Reset (When You've Forgotten Everything)

If you've forgotten the old code, can't get the keypad to respond, and the standard reset and clear-memory methods aren't working, the factory reset restores the opener to its out-of-the-box state.

1. On the keypad, press and hold the 0 and Enter buttons together for about 20 seconds.

2. Wait until you hear a long beep or until the keypad lights flash several times.

3. Release the buttons. The keypad and opener are now factory-reset.

4. Reprogram a new 4-digit PIN using the standard reset method (Learn button → enter PIN → hold Enter).

5. Re-pair any remotes you want to use.

Last resort only

Factory reset unpairs every device connected to your opener like keypads, remotes, smart home integrations, MyQ app pairings. Use it only when other methods have failed. Set aside 20–30 minutes to fully reconfigure your system afterward.

Tips for Choosing a Secure Garage Code

• Change your code at least once a year — even if nothing has happened. Routine rotation is the simplest security upgrade you can make.

• Avoid personal details - birthdays, addresses, phone numbers, anniversaries. Anyone with access to public records can guess these.

• Avoid obvious sequences - 1234, 0000, 1111, 2580 (a vertical line on the keypad). These are tested first by anyone trying to guess.

• Don't share the code over text or email - If you must give it out, do it verbally and in person.

• Replace keypad batteries before they die - A weak battery can cause the keypad to drop signals or lock you out of your own home.

Frequently Asked Questions

Q1. How do I reset my LiftMaster keypad without the old code?

You don't need the old code. Press and release the Learn button on the motor unit, this primes the opener for 30 seconds. While the LED is on, enter your new 4-digit PIN on the keypad and hold the Enter button until the opener's light blinks (or you hear two clicks). The old code is replaced.

Q2. Why doesn't my old code stop working after I set a new one?

Setting a new PIN doesn't automatically erase old codes from a LiftMaster opener, they remain stored. To fully clear all old codes and paired remotes, press and hold the Learn button until the LED goes off (about 6–10 seconds). This wipes all keypad codes and remote pairings, so you'll need to reprogram your remotes afterward.

Q3. How do I do a full factory reset on my LiftMaster keypad?

Hold the 0 and Enter buttons together for about 20 seconds until you hear a beep. This is the factory reset method and erases everything. Use this only as a last resort, you'll need to reprogram every keypad and remote afterward.

Q4. Can I program a temporary, one-time code for a cleaner or guest?

Yes, most LiftMaster keypads support temporary PINs that you can limit by hours or by number of openings. The exact steps vary by model. See our guide to changing your LiftMaster code for the temporary PIN flow.

Q5. Why won't my garage door open after I reset the code?

Two common causes: the keypad battery is low (replace the 9-volt or 12-volt battery), or the reset didn't take place and you need to repeat the Learn-button sequence. If the opener responds to the wall button but not the keypad, the issue is on the keypad side. If neither works and the opener's light is flashing 10 times, you likely have a safety sensor (photo eye) issue, see our keypad troubleshooting guide.

Q6. Does the reset process work on the myQ Video Keypad and Security+ 3.0 keypads?

No, newer keypads (myQ Video Keypad VKP1-LM and Security+ 3.0 models L979S/M/U) are managed through the myQ app rather than the Learn button. Open the myQ app, go to Settings → Devices → your keypad, and use the in-app reset option.

Q7. How often should I reset my LiftMaster garage door code?

Change your code at least once a year, or immediately if you suspect someone has it (after a tenant moves out, after a service visit, or if you've given the code to a contractor). It takes under five minutes and is the simplest security upgrade you can do.
