Features: High Compatibility: Most of the common remote control can be copied the operation is simple and it can be used immediately after copying. Good Hand Feel: Frosted design rubber buttons crisp feel and clear feedback. Slim and compact size easy to carry. Indicator Light: Built-in high brightness LED lamp beads the working status is clear at a glance. Wide Adaptability: It can be used in e-scooter garage doors gate access control and auto parts modification fields. Precondition: The original remote control's functionality is normal its chip is identical or compatible and its working frequency is the same. How to deal with the situation where some of the keys can control the rest cannot control? You can use clear and restore operation the specific operation is as follows: (1) first clear code; (2) after clearing code copy the unsuccessful key again and there is no need to copy the rest buttons; (3) and then clear the code again; (4) restore code; at this time the original keys that were not successfully copied are now covered by new codes and the original keys that were successfully copied are now retained. If there is no copy after the second copy of the keys repeat the above steps again and again until all keys are successfully copied. Tips: 1. The remote control can only copy the fixed code learn the code chip and part of the single-chip remote control (can copy the chip model see copyable chip type). 2. Two-way remote control rolling code remote control single-chip encryption program remote control cannot be copied. Such as HCS200 HCS201 HCS300 HCS301 and so on. 3. Before copying the remote control make sure that the existing code on the remote control has been cleared and check that the code is cleared successfully. Otherwise it cannot be copied. 4. Please ensure that your remote control has enough power the distance between the two remote control the better. 5. If the copy distance is too close to the switch at different angles to copy. Press and hold the button on the original remote control to send the signal completely normal and then press the button on the remote control to ensure that the function is completely copied.

Notice: Actual color may be slightly different from the image due to different display and light effect. Please allow 1-3cm deviation due to manual measurement. If you're not sure what chip it is you can turn on the remote and send us the photo. We will contact our technicians to check if it can be reproduced.
