Mando a distancia universal clonado para puertas de garaje, 433 MHz, llavero de repuesto para puertas eléctricas y portones (paquete de 2)

[Compatible IC Chips] This is a fixed/rolling frequency remote control cloner (433MHz) that can copy 99.99% of common fixed-code and learning-code remote controls. Compatible with most chips: This 433MHz automatic sliding door opener is compatible with 2260 and 1527 chips; please confirm your chip's compatibility before ordering. [Clear Old Codes] Press and hold the "A" and "B" buttons simultaneously—the LED indicator will flash 3 times. Then release the "B" button and press it again 3 times—the LED indicator will flash again. All stored data will be cleared. After clearing, the LED indicator will not light up regardless of which button is pressed on the remote control. [Easy Copying] Place both remote controls side-by-side on a table, keeping them at zero distance, and press the copy button on each. Copying is successful after the LED indicator flashes three times rapidly. Other button operations are the same. Some remote controls have low transmission power, so the original remote control needs to be placed next to the copy remote control before operation. Avoid noise interference during operation. 【Wide Range of Applications】Suitable for automobiles, garage doors, doors, sunroofs, car/motorcycle anti-theft alarms, home security products, short-range wireless remote control products, electrical appliances/smart home lighting, industrial control products, etc.
