Reset: Press and hold buttons A and B simultaneously until the LED flashes continuously, then release. If your remote does not have buttons A and B, press the top two buttons. Copy: Press and hold the button on the original remote you wish to copy, while simultaneously pressing and holding the corresponding button (A, B, C, D, etc.) on the new fob. Keep both remotes close together during the process. Programming is complete when the fobs LED flashes. Tips: To recover a previously copied code after reset, press buttons C and D (or the bottom two buttons) until the LED flashes. Notice: If programmed correctly, the fob should work immediately. If some buttons do not function, clean the contacts and repeat the copying process, observing LED behavior. If issues persist after multiple attempts, verify the original remotes chip type and frequency compatibility. Packing List: 10 x Remote Control Key Fobs
