How to Use
- Clear the Code: Press and hold the two upper buttons simultaneously. The LED will flash, then go out — continue holding. After 2 seconds the LED flashes again, confirming the code has been cleared. To verify, press any button: if the LED flashes once and goes out, clearing was successful.
- Copy the Code: Hold your original remote in one hand and this duplicator in the other, as close together as possible. Press the corresponding buttons on both remotes at the same time. The LED will flash continuously, confirming the button code has been successfully learned. Repeat for each of the remaining 3 buttons.
- Restore a Code: If a code is accidentally cleared, press and hold the two lower buttons simultaneously. After 3 seconds the LED lights up and then flashes quickly, confirming the code has been restored to the last saved version.

Frequently Asked Questions
Q: Will this 433MHz remote duplicator work with my existing garage door opener?
A: This universal remote duplicator is compatible with most fixed-code garage door openers and gate controllers that operate at 433MHz. It uses learning code technology to copy the signal directly from your original remote. It is not compatible with rolling-code (hopping-code) systems. Check your current remote's frequency label before purchasing to confirm compatibility.
Q: How many remotes can I copy onto this duplicator?
A: You can copy up to 4 different button functions — one per button. Each button on this 4-button duplicator can be programmed independently from the same or different original remotes, giving you flexible control over multiple devices if needed.
Q: What happens if I accidentally clear a saved code?
A: No problem! This duplicator features a built-in code restore function. Simply press and hold the two lower buttons simultaneously for 3 seconds until the LED flashes quickly — this retrieves the last saved code, so you won't need to re-copy from your original remote again.
Q: Does the battery come included?
A: Yes, a battery is included in the package. Your new 433MHz remote duplicator is ready to use straight out of the box with no additional purchases required.
