Brand new and high quality. Programming instructions: 1. Clear the existing code on our remote control duplicator 1) Click and hold the A and B buttons simultaneously - the LED light will flash 3 times. 2) Continue to hold the A button and release the B button. 3) Continue to hold the A button and press the B button 3 times, the LED light will start to flash continuously. Now press any button on the remote control, the LED light will not turn on, so the code deletion is successful; if you press the button and the LED light turns on, it indicates that the original code has not been deleted! 2. Clone your original remote control 1) Place both remote controls in reverse position. Make sure they have direct contact. 2) Click and hold a button on your original remote control and a button on your cloned remote control. Hold until the LED light flashes twice. 3) The flashing then becomes constant and you have successfully cloned. (the left keys follow the same operation above) If for some reason the clone does not go beyond 2 flashes, it means the signal is not going through, move the remote control slowly up and down until you reach the point where it goes through.
