If your remote stopped working—or you suspect a neighbor’s remote can open your door—you likely need a Genie Blue Max Garage Door Opener Reset Code. Unlike modern openers with “learn” buttons, Blue Max systems use dip switch coding that must be changed manually. The good news: resetting the code takes just a few minutes and requires no special tools.
This guide shows you how to change the dip switch pattern, sync your remotes, and restore secure control.
How Blue Max Coding Works (Why You Must Reset Manually)
4
The Genie Blue Max garage door opener uses:
- 9 or 12 dip switches
- Fixed 390 MHz signal
- Identical switch pattern in opener and remote
There is no reset button. Changing the code means physically changing the switch pattern.

When Should You Reset the Code?
Resetting is recommended if:
- Remote suddenly stops working
- You lost a remote
- Door opens randomly
- You moved into a new home
- You suspect code duplication nearby
Step 1: Locate Dip Switches in the Opener
- Unplug the opener.
- Remove the light cover.
- Find the small dip switch bank on the receiver board.
- Count switches (9 or 12).
This is the “master code.”
Step 2: Choose a New Dip Switch Pattern
Create a new ON/OFF pattern different from the old one.
Example New Pattern (9 Switches)
| Switch | Position |
|---|---|
| 1 | OFF |
| 2 | ON |
| 3 | OFF |
| 4 | ON |
| 5 | ON |
| 6 | OFF |
| 7 | OFF |
| 8 | ON |
| 9 | OFF |
You can choose any combination.
Step 3: Set the Same Pattern on All Remotes
- Open remote battery cover.
- Use pen tip to adjust switches.
- Match opener pattern exactly.
- Insert battery and test.
Time required: 3–5 minutes per remote.
Step 4: Test the New Code
Plug the opener back in and test:
- Remote function
- Wall button
- Door response
If it fails, recheck switch alignment.
Common Mistakes When Resetting the Code
| Mistake | Result |
|---|---|
| One switch misaligned | Remote won’t work |
| Using Intellicode remote | Incompatible |
| Forgetting to update all remotes | Some won’t function |
| Not unplugging during change | Risk of short |
Why Resetting Improves Security
Dip switch systems are less secure than modern rolling codes. Resetting:
- Prevents old remotes from working
- Avoids neighbor interference
- Restores private access
