How to Use
Step 1 – Clear the Code
Hold the unlock and lock keys simultaneously. The LED will flash 3 times rapidly within ~2 seconds. Release one finger, then quickly press that button 3 more times until the LED flashes rapidly. Release both fingers. Press any key — if the LED turns off, the code has been cleared successfully.
Step 2 – Clone/Copy
Hold the original remote in one hand and the new duplicator in the other. Bring them as close together as possible. Press the matching key on both remotes simultaneously. Within ~2 seconds, the LED flashes twice. After one second, the indicator keeps flashing — release your fingers, then press the copied key. If the LED stays on, the code has been successfully copied. Repeat for each button.
Step 3 – Restore
If a code is accidentally cleared, simultaneously press the two bottom keys on the duplicator. The LED will flash quickly. Release, then press any key. When the light stays on, the code is restored.
Troubleshooting: Some Buttons Work, Others Don't?
- Clear the code.
- Re-copy only the unsuccessful key(s).
- Clear the code again.
- Restore — the newly copied codes are added while the previously successful ones are retained. Repeat as needed until all keys copy successfully.
