Copying Steps

Rolling Code/Fixed Code Copying Method:

Press and hold buttons A and B simultaneously, release button B, and then press button B three times consecutively.

Release all buttons, and the LED will start flashing red.

Place the original remote control close to the cloner (distance ≤3cm).

Press the button on the original remote control and wait for the cloner's red LED to turn blue.

Press the corresponding button on the cloner to confirm (e.g., press the first button to copy the first key).

The LED turning off indicates successful copying of that key.

Repeat steps 3-6 to copy other keys (a 4-key remote requires copying each key separately).

After copying, re-pair the cloner with the receiver for use.

Applications

Garage door remote control replication

Access control system remote backup

Smart home remote management

Car remote control backup

Precautions

⚠️ Ensure the original remote control has sufficient power during copying.

⚠️ Keep the two devices in close contact (≤3cm) during the copying process.

⚠️ Some highly encrypted remotes may not be copyable.

⚠️ Always re-pair with the receiver after copying.

⚠️ Comply with local radio management regulations.
