433.92 MHz four-button remote duplicator

This handheld duplicator copies the signal from an existing 433.92 MHz remote into its own four buttons. Each button stores one code independently and the unit can repeat the process up to one million times. It is built from ABS plastic and measures 63 x 37 x 12 mm with a weight of 35 g.

For owners of compatible fixed-code remotes

The duplicator suits users who have a working 433.92 MHz remote for a garage door, rolling shutter, alarm or automatic gate and want a compact backup. It will not work with encrypted or rolling-code systems that change the transmitted code on every press, so buyers with those installations should look at a different solution.

Four independent channels with up to 100 m range

Each of the four buttons holds a single copied code, giving headroom for up to four different doors or gates. In open areas the radio reaches 30 to 100 m, which covers typical driveway and yard distances. Thick walls, metal structures or strong local interference will reduce the effective range.

Questions about this item

What existing remote do I need to copy its signal onto the 433.92MHz 4-button duplicator?

You need a working original remote that operates on 433.92MHz so the duplicator can scan and clone each button code one-to-one.

Will the duplicator interfere with my older 433.92MHz garage receiver when both are in use?

The duplicator only transmits while you press a copied button; it does not continuously broadcast, so normal operation alongside an existing receiver is unaffected.

How can I verify the duplicator copied each button correctly after setup?

Stand within 30-100m of the target device in an open area and press each of the four buttons; the garage door, alarm or rolling shutter should respond to every press.
