How To Erase All Codes From Garage Door Opener (Step-By-Step)
This procedure works on most LiftMaster, Chamberlain, Craftsman, Genie, and similar openers with a Learn, Set, or Program button.
Important: Erasing codes removes all remotes, keypads, and car-programmed HomeLink systems. You must reprogram each device afterward.
Step 1 — Locate the “Learn” or “Program” Button
You will usually find it:
- Under the opener’s light cover
- On the back panel
- Near the antenna wire
Common button colors (indicate system type):
Yellow, Purple, Red/Orange, Green
Step 2 — Press and Hold the Learn Button
Use your finger (no tools needed).
- Hold for 6–10 seconds.
- An LED will turn off, blink, or the opener light will flash.
This signals that the opener has cleared every stored code.
Step 3 — Test to Confirm Reset
Try your remote or wall keypad.
- If none of them operate the opener → reset successful
- If any still work → repeat Step 2 and hold longer (up to 12 seconds)
Step 4 — Reprogram Your Devices
You must re-add each device:
- Remotes
- Wireless keypads
- Cars with HomeLink
- Smart garage controls
Every manufacturer reprograms differently, but most require:
- Press Learn button
- Press desired remote button until opener flashes
You now have a fresh, secure system.

How Garage Door Code Storage Works
Understanding the system helps ensure the process is done correctly.
Most modern openers use:
- Rolling code technology (changes every time you press the remote)
- Secure memory chips that store unique device IDs
- 2.4 GHz interference-resistant signals
High-reliability models can store up to 50 devices, depending on brand.
Clearing codes wipes this memory entirely.
