How to Use
Step 1 – Clear Existing Code
Hold the two upper buttons simultaneously until the LED flashes and then goes out (approx. 2 seconds). The LED will then begin flashing, confirming the code has been cleared.
Step 2 – Copy Your Original Remote
Hold your original remote in your left hand and the duplicator in your right. Bring both remotes as close together as possible. Press the corresponding buttons on both remotes at the same time and hold until the LED flashes continuously — this confirms the button code has been learned.
Step 3 – Verify & Repeat
Press any button on the duplicator — if the LED flashes once and goes out, the code is successfully stored. Repeat for each of the remaining buttons (up to 4 total).
Step 4 – Recovery (if needed)
If a code is accidentally cleared, press the two lower buttons simultaneously. After 3 seconds the LED will light and then flash rapidly, indicating the previously stored code has been restored.

It does NOT work with rolling-code (hopping code) systems. Check your original remote or opener manual to confirm it uses a fixed code at 433MHz before purchasing.
Q: Is a battery included, and how long will it last?
A: Yes, a DC 12V battery is included so you can use the remote duplicator straight out of the box. With an operating current of less than 8 mA, battery life is excellent under normal use conditions.
Q: How many buttons can I copy onto the duplicator?
A: The 433MHz remote duplicator supports up to 4 individual button channels (A, B, C, D), making it ideal for systems with multiple zones, doors, or gates controlled by a single remote.
Q: What is the effective range of this remote transmitter?
A: In open areas, the RF transmission range is 50–100 metres. Range may be reduced in environments with walls, interference, or other RF devices nearby.
