3. Setup and Programming

The Marantec M3-2312 remote control can be programmed using an existing, working remote or directly to your garage door opener. Ensure your garage door opener is a Marantec model operating at 315 MHz.

Method 1: Programming from an Existing Remote (Cloning)

This method requires a working Marantec remote control and a short length of wire (e.g., a paperclip or small jumper wire) to connect the programming connectors.

1. Open both the existing, working remote and the new M3-2312 remote to access their internal programming connectors. These are typically small metal pins or ports.
2. Using a small wire, connect the corresponding programming connectors on both remotes. Ensure a secure connection.
3. On the existing, working remote, press and hold the button you wish to copy. The LED on the existing remote may illuminate.
4. While still holding the button on the existing remote, press and hold the desired button on the new M3-2312 remote.
5. Hold both buttons until the LED on the new M3-2312 remote flashes rapidly or changes color, indicating successful programming. This may take several seconds.
6. Release both buttons and disconnect the wire.
7. Test the new remote with your garage door opener. If it does not work, repeat the steps.

Note: If you attempt to program a second remote directly to the opener after programming the first via cloning, the opener may issue a new code, causing the first cloned remote to cease functioning. It is recommended to clone all new remotes from a single master remote if possible.

Method 2: Programming Directly to the Garage Door Opener

Refer to your specific Marantec garage door opener's instruction manual for detailed steps on how to put the opener into programming mode. Generally, this involves pressing a
