Paquete de 2 mandos a distancia universales de cuatro botones para puertas de garaje de 433 MHz

Important Note: Only compatible with 433 MHz fixed-code remote controls. This product is a replacement and not an original accessory. Only compatible with specified models and frequencies; not applicable to other models or frequencies. Please confirm your purchase, thank you. Flexible Garage Door Remote Control: This is a fixed-frequency copier that can copy commonly used fixed codes. The button with 4 programmable control switches can copy up to 4 remote control signals. This means you can transfer the functions of multiple remote controls to one, making your life easier. Simple Pairing: Place the copied remote control and the original remote control side-by-side on a table and press the copy button on each; when the LED indicator flashes three times rapidly, it indicates successful copying; other buttons operate in the same way. If copying fails, please clear the code and copy again. (Please note: This universal remote control can only copy the frequency of a working original remote control.) Compact and Portable: Convenient keychain design allows for easy attachment to your car keys. Sliding cover protection prevents accidental button presses, portable and easy to use. Wide range of applications: car remote garage door openers, garage doors, cellar lighting, car/motorcycle alarm systems, home security products, short-range wireless remote controls, electrical appliances/home lighting, industrial control products, etc.
