Features: New and high quality. Copy and control any remote with the SOB02-KB circular two-button copy remote. Its SA901A main control chip allows for online programming and repeated burning, making it easy to copy other remotes in the same frequency range. Built-in EEPROM ensures convenient and fast use in car remote, lighting control, and smart home remote applications. The SOB02-KB operates at 315MHz/433.92MHz and runs on a CR2032 button battery. Made of durable ABS material, this remote is lightweight and compact at just 50x50x14mm (with casing). Its low static current and transmission power make it an ideal choice for many different devices. Anyone can benefit from the SOB02-KB's easy-to-use copy function. Whether you're controlling a car, lights, or home automation devices, this remote makes it simple to learn new codes and operate multiple remotes at once. Use the SOB02-KB wherever you need remote control access. It's perfect for situations where multiple remotes are needed, such as in a garage or home theater. Plus, its compact size makes it easy to carry with you wherever you go. Remember to keep the SOB02-KB out of reach of children, and be sure not to exceed the recommended voltage range. For best results when copying remote codes, ensure that both remotes are close together to avoid interference.
