Why Clearing Codes Matters on Your Chamberlain Garage Door Opener

You’ve purchased a used home and want to remove previous owners’ access.
Your remote was lost or stolen, and you want to prevent unauthorized access.

How To Clear Codes On Chamberlain Garage Door Opener – Step-by-Step Instructions

Clearing garage door opener codes on a Chamberlain unit is typically a fast and simple process. Most models use a similar method involving the “Learn” button.

Step 1: Locate the “Learn” Button

Use a ladder to safely reach your garage door opener mounted on the ceiling.
On the back or side of the motor unit, find the “Learn” button. It’s often near the antenna wire and may be red, yellow, purple, or orange depending on your model.
Nearby, you’ll likely see an LED light—this helps indicate when certain actions are complete.

Tip: If you have a Chamberlain wall-mounted (side-mounted) opener, the Learn button may be behind a light cover or on the side panel.

Step 2: Press and Hold the Learn Button

Press and hold the Learn button for about 6–10 seconds.
The LED next to the button will light up and then turn off.
When the light goes off, it means all programmed remote controls, keypads, and wireless devices have been erased.

What Gets Erased When You Clear Codes?

It’s important to know exactly what you’re resetting:

All remote controls linked to the opener
All keyless entry keypads
Any integrated smart devices (e.g., myQ-compatible devices)
Connections to home automation systems (depending on your model)

You’ll need to reprogram everything after clearing the codes. Make sure you have access to your remotes and WiFi credentials (if using myQ) before starting the process.

Reprogramming Devices After Code Reset

Once the codes are cleared, you’ll want to add back the devices you still use:

Reprogram Remote Controls

Press the Learn button once (do not hold).
The LED will begin to blink.
Within 30 seconds, press the button on your remote control that you want to program.
When the opener’s lights blink or you hear two clicks, programming is successful.

Reprogram Keyless Entry (Wireless Keypad)

Press the Learn button once.
Enter your desired 4-digit PIN on the keypad and press the Enter button.
Look for the light to blink, confirming the programming.

Reconnect myQ Smart Devices

Open the myQ app on your phone.
Go to Device Settings > Add New Device.
Follow the in-app instructions to reconnect your garage door opener to WiFi.

Common Issues When Clearing Codes and How to Fix Them

While clearing codes is generally straightforward, here are a few issues that may arise:

1. The Learn Button Doesn’t Work

Ensure the opener has power and is functioning.
Some units require a firm press on the Learn button.
If the button is unresponsive, unplug the opener for 30 seconds and try again.

2. You’re Not Sure If Codes Were Cleared

Try pressing your old remote. If the door doesn’t move, the code was cleared successfully.
Alternatively, hold the Learn button again until the LED turns off.

3. Lost Access to myQ After Clearing

Clearing codes can also disconnect the garage door from your myQ app. You’ll need to set up the device again through the app.

Note: The garage door opener must be on a 2.4GHz WiFi band to reconnect properly.

Resetting your Chamberlain garage door opener is not just for convenience—it also plays a role in home safety:

Label remotes and store spares safely
Change keypad PINs every few months for added security
