Features: Brand new and high quality. Easy to use and fast. Can be used in car remote control, lighting control, smart home remote control, and other fields. If the remote control needs to be coded, it is necessary to clear the existing code first. Code matching operation: Press and hold a button on the copied remote control and a corresponding button on the copying remote control simultaneously until the indicator light on the copied remote control changes from flashing rapidly to steady, indicating that the code matching is successful. Then release both buttons. Repeat this operation for other keys until all keys are copied. The copy remote control uses a 12F683 main chip, supports online programming, can be reprogrammed multiple times, and has built-in EEPROM. It can copy other common frequency remotes and allows code clearing and relearning at any time. To clear the code: Press and hold the two buttons on the top of the copy remote control (the two buttons near the indicator) until the indicator starts blinking. Then press one of the two buttons three times to clear the code (continue holding the other button throughout the process). To restore previously cleared remote control codes: Press and hold the two buttons on the bottom of the copy remote control simultaneously until the indicator light flashes rapidly.
