Important Compatibility Notes

• This duplicator copies fixed-code remotes only. It is compatible with fixed-code chips and some learn-code chips.
• It cannot copy rolling-code, two-way, or single-chip encrypted remotes (e.g. HCS200, HCS201, HCS300, HCS301).
• Your original remote must be in normal working condition and operating at 433MHz for cloning to succeed.
• Always clear any existing stored codes on this duplicator before beginning the copy process.

How to Copy (Quick Guide)

1. Clear Code: Simultaneously hold the unlock and lock keys until the LED flashes 3 times rapidly (~2 seconds). Release one finger, then quickly click that button 3 more times until the LED flashes quickly. Release both fingers, then press any key — when the LED goes off, the code is cleared.
2. Copy: Hold both the original remote and this duplicator as close together as possible. Press the matching button on both simultaneously. When the LED flashes twice quickly and then stays on, the key has been successfully copied. Repeat for each button.
3. Restore: If you accidentally clear a copied code, press the bottom two keys simultaneously, wait for the LED to flash, release, then press any key. The LED staying on confirms the code has been restored.

Frequently Asked Questions

Q: What type of remote codes can this 433MHz duplicator copy?

A: This universal remote duplicator is designed to copy fixed-code signals and some learn-code chip remotes operating at 433MHz. It cannot clone rolling-code, two-way, or encrypted single-chip remotes such as those using HCS200, HCS300, or HCS301 chips.

Q: How do I know if the code has been successfully copied?

A: After pressing the matching buttons on both remotes simultaneously, the LED indicator on the duplicator will flash twice quickly and then remain on — this confirms a successful copy. If the LED does not stay on, repeat the process, ensuring both remotes are as close together as possible.

Q: Can I use this remote for multiple garage doors or gates?

A: Yes! With 4 independent channels, you can copy up to 4 different fixed-code buttons — making it possible to control multiple compatible garage doors, electric gates, or access systems all from one convenient remote duplicator.

Q: What should I do if only some of the buttons work after copying?

A: If some buttons copy successfully but others do not, you can use the clear, re-copy, and restore sequence: first clear all codes, then re-copy only the unsuccessful keys, clear again, and finally restore. This overwrites failed copies while retaining the successful ones. Repeat as needed until all keys are working.
