Replacement Garage Door Remote for Genie G3T-R G3T-BX, 3-Button Intellicode, 315/390MHz

Replacement Remote for Genie Intellicode and Overhead Door CodeDodger

A replacement 3-button remote for Genie Intellicode and Overhead Door CodeDodger openers. Each button can be pointed at a different door, the remote seeks both 315 MHz and 390 MHz on its own, and the code rolls on every press. The CR2032 battery, visor clip and printed instructions are in the box.

Before You Buy: Intellicode Only

How Many Doors It Controls

The number of doors depends on when your opener was built, because older openers only accept the two upper buttons.

Compatible Models — 22 Remote Models

Match the model number printed on your existing remote to this list. Grouped by series, all models below are Genie Intellicode and Overhead Door CodeDodger.

Intellicode Rolling Code and Auto-Seek 315/390 MHz

Intellicode is a rolling code system. The access code changes on every button press, so a signal captured once cannot be replayed later. That is also why an Intellicode remote cannot be cloned by holding two remotes back to back — that trick only works on fixed-code remotes.

Auto-Seek is the dual frequency part. Genie Intellicode openers were built on both 315 MHz and 390 MHz over the years. Instead of asking you to pick one, this remote looks for the opener on both bands and uses whichever gives the cleaner signal, so a neighbouring device on one frequency is less likely to block the door.

Overhead Door sells this rolling-code system under the name CodeDodger. CodeDodger I and CodeDodger II both operate on 315/390 MHz — the same two bands this remote seeks. So whether the opener is labelled Intellicode or CodeDodger, the remote is looking on the same two bands for the same rolling-code signal.

How Your Opener Learns the Remote

The opener does the learning — nothing is programmed inside the remote itself. Which of the two methods below applies depends on your opener:

Openers and add-on receivers made 1995 – 2011

Press and release the Learn Code button on the opener power head once. The red LED begins to flash.

Newer openers

Press and hold the program button until the round LED turns blue, then release. The small LED goes out and the long LED flashes purple.

Then, while the opener is in programming mode

1. Pull the protective battery tab from the remote and stand at least 5 ft (1.5 m) from the opener.
2. Slowly press and release the button you want to use two times. The opener LEDs flash and go out — that is the confirmation.
3. Press and release the same button a third time and the door moves. If the LEDs do not go out, the press was too quick or too light — press several more times.

Steps follow Genie’s published G3T-R programming instructions. On openers made 1995–1997 use the two upper buttons; on 1997 and later any of the three buttons can be programmed.

Specifications and What’s in the Box

Frequently Asked Questions

Which openers does this remote work with?

Genie Intellicode and Overhead Door CodeDodger openers made from 1995 onwards. It does not work with fixed-code or DIP-switch openers, and it does not work with LiftMaster, Chamberlain, Craftsman or Linear openers.

How many doors can it control?

Up to 3 doors on openers made from 1997 to today, using any of the three buttons. On openers made 1995–1997 it controls up to 2 doors, because those openers only accept the two upper buttons.

Is it rolling code or fixed code?

Rolling code. Intellicode changes the access code on every press, which is why it cannot be copied from another remote the way a fixed-code remote can.

What is the difference between this and the 2-button Genie remote?

This one has three buttons, covers 315 and 390 MHz automatically, and controls up to 3 doors. The 2-button ACSCTG Type 1 remote runs on 390 MHz only, controls 2 doors and ships as a 2-pack.

Will it work with a DIP-switch opener?

No. DIP-switch openers use fixed codes set by small switches, which Intellicode remotes cannot transmit.

What battery does it take?

A CR2032 coin cell, already fitted. To replace it, open the case with a coin or washer in the slot at the top of the remote and match the polarity symbols inside the battery housing.

Can I use it with HomeLink or Car2U?

HomeLink and Car2U work by learning a signal from a remote that already opens your door. If your vehicle’s system accepts this remote’s signal, it learns it the same way it would learn the original — follow the pairing steps for your vehicle.

Is G3T-BX the same remote as G3T-R?

Yes. Genie lists this transmitter as “G3T-R or G3T-BX” — two model numbers for the same 3-button dual-frequency remote. In the list above it is cross-referenced as ACSCTG Type III (Type 3). If your old remote carries any of those three designations, this is its replacement.
