One set includes two universal remote controls, suitable for garage doors and fences—an ideal alternative.

Note 1: This remote control is only compatible with 433MHz remote controls; it is not compatible with rolling code remote controls or transmitters that emit billions of signals. Please check the operating frequency of your old remote control before purchasing.

Note 2: This remote control is only compatible with the chip types specified in the product description. Please check compatibility with your existing chip before purchasing. The four buttons (A, B, C, D) on the remote control can be used with four different chip types to control four different devices. It only operates at a 433MHz frequency, with an effective range of 50 to 100 meters (open space), providing a unique user experience and making it ideal for everyday use.

It can accurately and efficiently copy your current remote control, making it an ideal replacement for a lost remote control.
