Genie G3T-A 3-Button Garage Door Opener Remote Compatible Models

• Genie Intellicode I & II openers

What Is Intellicode and Why Does It Matter?

Intellicode is Genie’s rolling code security system.

Every time you press the remote:

• A new access code is generated
• Old codes become invalid
• Over 4 billion combinations are possible

If your opener uses Intellicode, the G3T-A is likely compatible.

How Do I Know If My Genie Opener Is Compatible?

This is one of the most common homeowner questions.

Step 1: Check the Learn Button Color

Look at the motor head unit mounted on your ceiling.

Common compatible button colors:

• Purple
• Red
• Green

These typically indicate Intellicode compatibility.

Step 2: Check Manufacture Date

If your opener was made:

• 1997 or later → Likely compatible
• Before 1995 → Likely NOT compatible

Step 3: Look for Dip Switches

If your remote or opener has small dip switches inside, it is an older fixed-code model and not compatible with G3T-A.

What Is NOT Compatible With the Genie G3T-A?

The Genie G3T-A is NOT compatible with:

• Pre-1995 Genie dip-switch systems
• Very early fixed-code remotes
• Some commercial-only industrial openers
• Certain third-party brands

If your system uses a fixed code instead of rolling code, you will need a different remote model.

How to Program the Genie G3T-A Remote

Once you confirm compatibility, programming takes just minutes.

This makes it ideal for homes with multiple garage bays.

Genie G3T-A vs Universal Remotes

Some homeowners consider universal remotes.

Genie G3T-A

Pros:

• Guaranteed Intellicode compatibility
• Reliable signal strength
• Simple programming

Cons:

• Works mainly with Genie/Overhead Door systems

Universal Remote

Pros:

• Works with multiple brands
• Flexible programming

Cons:

• More complex setup

If you own a Genie opener, the G3T-A is often the safer choice.

Operating Range and Performance

Typical range:

• 50–150 feet

Range depends on:

• Battery strength
• Interference from WiFi routers
• Concrete walls
• Metal garage doors

Replacing the battery restores most range issues.

Battery Replacement Guide

The Genie G3T-A uses:

CR2032 3V lithium coin battery

Replacement Steps

1. Use small flathead screwdriver.
2. Gently open casing.
3. Replace battery (positive side up).
4. Snap remote closed.

Battery lifespan averages 2–5 years.

Troubleshooting Compatibility Issues

If the remote won’t pair:

• Confirm opener uses Intellicode
• Replace battery
• Clear opener memory
• Stand within 3–5 feet during programming

To Clear Opener Memory

1. Hold Learn button for 10 seconds.
2. LED will stop blinking.
3. All remotes erased.
4. Reprogram.

Cost and Value

Average U.S. retail price:

$25–$45

Compared to replacing a full opener (which can cost $300–$800), the G3T-A is cost-effective.

Safety Considerations

• Test safety reversal system monthly

Garage door openers are powerful mechanical systems and require regular safety checks.
