Step-by-Step: How To Change Code On Legacy Garage Door Opener (Learn Button Method)
This is the most common method on modern Legacy models.
Step 1: Erase the existing codes
To remove all old remote access:
- Press and hold the Learn button for 8–10 seconds
- The LED light will shut off or blink
- Release the button
✅ All previous remotes and keypads are now deleted.
This step is essential if you’re concerned about security.
Step 2: Activate learning mode
- Press the Learn button once (don’t hold)
- The LED light will begin blinking
- You now have 30 seconds to add a new device
This puts the system in “listening mode.”
Step 3: Program your new remote
- Hold your remote control close to the motor unit
- Press the button you want to program
- Hold for 2–3 seconds
- The light will flash or click
✅ The remote is now connected to your opener.
Step 4: Add a keypad code (optional)
If you use a keypad outside the garage:
- Enter your new 4–6 digit code
- Press “Enter”
- The garage light will blink
Choose a code that is:
- Not your birth year
- Not your house number
- Not something easy like 1234
A smart choice increases safety instantly.
Step 5: Test your new code
Test from at least three distances:
- 5 feet
- 15 feet
- 25–30 feet
If the garage opens and closes smoothly, the process worked.
How To Change Code On Legacy Garage Door Opener (Dip Switch Method)
Older Legacy openers don’t use Learn buttons. Instead, they use dip switches — tiny toggles inside the remote and motor.
If your model is old, follow these steps:
- Remove the battery cover on your remote
- You will see 8–12 tiny switches
- Write down the current pattern
- Use a pen to change the pattern
- Open the motor cover and match the same switch positions
- Replace all covers and test
✅ Changing even one switch creates a new access code.
