Check your existing remote for a \"433MHz\" or \"433.92MHz\" frequency label. If your current remote operates on a different frequency (such as 315MHz or 868MHz), this duplicator will not be compatible.\u003c\/p\u003e\n\n\u003ch4\u003eQ: How do I clone my existing remote signal onto this duplicator?\u003c\/h4\u003e\n\u003cp\u003eA: The cloning process is straightforward. Hold your original remote close to the duplicator, press and hold the corresponding button on the duplicator until the indicator light confirms the signal has been saved. You can repeat this for up to 4 different remotes — one signal stored per button. No technical expertise is required.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Can this remote duplicator copy rolling-code remotes?\u003c\/h4\u003e\n\u003cp\u003eA: This device supports learning-code (sometimes called rolling-code) remotes for a wide range of compatible IC chips listed above. However, fully encrypted rolling-code remotes using HCS200 or HCS300 chips cannot be copied. If your remote uses a standard 433MHz fixed or learning code chip from the compatible list, it should work successfully.\u003c\/p\u003e\n\u003c!-- production-packaging-notice --\u003e\n\u003ch3\u003eProduction \u0026amp; Packaging Notice\u003c\/h3\u003e\n\u003cp\u003eTo maintain high stock availability and fast shipping times, our items are sourced from multiple verified manufacturing facilities.
