433 MHz remote duplicator for gate and car codes

This device copies the signal from an existing 433 MHz remote so a single handset can open a garage door, a gate or a car. It is intended for homeowners or installers who need a spare or replacement transmitter without buying a brand-specific unit. The cloning process works with many fixed-code and learning-code remotes operating on the same frequency.

Internal power cable for compact installation

The unit draws power through an internal cable that connects directly to the control board of the opener, eliminating the need for batteries. This wiring approach keeps the duplicator hidden inside the motor housing and ensures it remains powered whenever the opener is active. Build quality uses standard connectors that fit common terminal blocks on 433 MHz receiver boards.
