Reset Your Code Using the Learn Button on the Opener Unit
The fastest way to reset a Chamberlain garage door code is to press and hold the Learn button on the back or side of your opener unit for about 6 seconds until the light blinks or goes out. This erases all remote controls and keypads from memory. You will then need to reprogram any remotes or keypads you want to use.
The Learn button is usually a small, colored button (often green, red, or yellow depending on your model) located near the antenna wire on the motor unit itself. You do not need to open the garage door or do anything else—just hold the button until the indicator light responds. This takes about 30 seconds total from start to finish.
After you press Learn, your old codes will no longer work. Any remote control or keypad that was previously programmed will be locked out. This is useful if you have lost a remote, moved to a new home, or want to clear out old devices before selling the opener.
Key Takeaways
- Press and hold the Learn button on your opener motor for 6 seconds to erase all programmed remotes and keypads at once.
- The Learn button is located on the back or side of the motor unit near the antenna and is usually colored green, red, or yellow.
- After resetting, you must reprogram each remote or keypad you want to use by pressing Learn again and then the remote button.
- Resetting the code does not affect your garage door's operation—it only clears the wireless devices that control it.
- If you cannot find the Learn button or your model does not have one, check your owner's manual or the Chamberlain website for your specific opener type.
Reprogram Your Remote After Resetting
Once you have cleared the old code by holding Learn, you need to reprogram each remote or keypad you want to use. Stand within 3 feet of the motor unit and press the Learn button again—this time for just 1 to 2 seconds until the light blinks. The opener is now in learning mode and will accept a new remote.
While the light is still blinking, press the button on your remote control that you want to use to open and close the door. Press it once and wait. The light should blink again or change color to confirm the remote has been learned. You can now move away from the unit and test the remote from your car or driveway.
Repeat this process for each remote or keypad. If you have multiple remotes, press Learn once, then program each remote one at a time while the light is still blinking. Most Chamberlain openers can learn up to 16 different remotes or keypads.
Reset a Keypad Code Without Touching the Motor Unit
If you only want to change the keypad code and not erase all your remotes, you can reset the keypad separately. Most Chamberlain keypads have a small reset button on the back or inside the battery compartment. Press and hold this button for 10 to 15 seconds until the light flashes or the keypad beeps.
After resetting the keypad, you will need to reprogram it to your opener. Stand near the motor unit, press Learn for 1 to 2 seconds, then press any button on the keypad. The keypad light should flash to confirm it has been learned. You can then set a new personal identification number (PIN) by following the keypad's menu—usually by pressing a menu or settings button and entering your new code.
Check your keypad's manual for the exact steps to set a new PIN, as the process varies by model. Some keypads require you to enter a default code first before you can create a custom one.
Clear a Single Remote Without Resetting Everything
If you only want to remove one remote from your system—for example, because you lost it or gave it away—you do not have to erase all your devices. Some Chamberlain models allow you to delete individual remotes by pressing Learn three times in quick succession. The light will flash a different pattern to show the unit is in deletion mode.
Then press the button on the remote you want to remove. The light should flash again to confirm that remote has been deleted. This method works on many newer Chamberlain openers, but not all models support it. If your opener does not respond to three quick presses of Learn, you will need to reset the entire system using the 6-second hold method instead.
Consult your owner's manual or the model number on your motor unit to confirm whether your opener supports single-remote deletion. You can also contact Chamberlain customer service with your model number, and they can tell you which method applies to your unit.
Locate Your Model Number and Owner's Manual
Your Chamberlain opener's model number is printed on a label attached to the motor unit, usually on the back or side near the Learn button. It typically starts with "LiftMaster" or "Chamberlain" followed by a series of numbers and letters. Write this number down before you start any reset process.
Once you have the model number, visit the Chamberlain website and search for your model in their support section. You can read the owner's manual as a PDF, which will show you exactly where the Learn button is on your specific unit and walk you through the reset and programming steps with diagrams. The manual also lists any special codes or procedures unique to your opener.
If you cannot find the manual online, call Chamberlain's customer service line with your model number. They can email you the manual or walk you through the reset process over the phone. Keep the manual in a safe place for future reference.
Troubleshoot If Your Remote Will Not Program
If you press Learn and the light does not blink, or if your remote still will not work after programming, check that the remote's batteries are fresh. Replace the batteries with new ones and try again. A weak battery is the most common reason a remote will not program or respond.
Make sure you are standing within 3 feet of the motor unit when you press the remote button during programming. If you are too far away, the opener may not receive the signal. Also confirm that you are pressing the correct button on the remote—some remotes have multiple buttons, and you may have programmed the wrong one by mistake.
If the light on the motor unit blinks but the remote still does not work after programming, try pressing Learn again and repeating the programming steps. Sometimes the signal does not register the first time. If the problem persists after three attempts, the remote itself may be faulty, or there may be an issue with your opener's receiver. Contact Chamberlain support with your model number for further help.
Frequently Asked Questions
Will resetting the code stop my garage door from opening?
No. Resetting the wireless code only erases the remotes and keypads that control the door. The door itself will still open and close normally if you use the wall button or the emergency release. You just will not be able to use any remote controls until you reprogram them.
How many remotes can I program to one Chamberlain opener?
Most Chamberlain openers can learn up to 16 different remotes or keypads. If you try to program a 17th device, you will need to erase one of the old ones first using the deletion method or by resetting the entire system.
Can I reset the code if I do not have the original remote?
Yes. You can reset the opener using only the Learn button on the motor unit. You do not need the original remote. After resetting, you can program any compatible Chamberlain remote or keypad to the opener, even if it is a different brand or model than the original.
What if I forget my keypad PIN after resetting it?
Reset the keypad itself by pressing the reset button on the back for 10 to 15 seconds, then reprogram it to your opener and set a new PIN. If you cannot find the reset button, remove the batteries for 30 seconds and reinsert them. This will clear the keypad's memory on most models.
Do I need to reset the code when I move to a new house?
It is a good idea to reset the opener if the previous owner left remotes behind or if you are concerned about who may have a remote. Press Learn for 6 seconds to erase all old devices, then program only your own remotes. This ensures only you can open the door.
