This is the exact process most homeowners need. Read once, then follow along near your opener.
Step 1 — Prepare the Area
- Make sure the garage door is fully closed
- Stand within 3–6 ft (1–2 m) of the motor unit
- Confirm the remote battery is working (LED lights when pressed)
Step 2 — Find the Learn Button on the Opener
Look on the back or side of the motor head. It may be under the light lens, near the antenna wire.

- An LED will glow for ~30 seconds (programming window)
Step 4 — Program a Remote Button
- Press and hold the chosen button on the 893LM for 2–3 seconds
- Release when the opener light blinks or you hear a click
Step 5 — Test
Press the programmed button. The door should move immediately.
If nothing happens, repeat the steps and ensure you complete them within the 30-second window.
How Do You Program All Three Buttons for Different Doors?
You can assign each button to a different opener.
- Button 1: Main garage
- Button 2: Second garage / workshop
- Button 3: Gate operator
Repeat the same Learn-button process for each opener, one at a time.
How to Erase All Remotes from the Opener (Security Reset)
If a remote is lost, clear the opener memory:
- Press and hold the Learn button for 6–10 seconds
- The LED turns off → memory cleared
- Reprogram only the remotes you still have
This prevents old remotes from operating your door.
