The reduction in signal strength is a natural characteristic of the carbon fiber. It's an excellent material,While we have taken measures to address the signal interference issues caused by genuine carbon fiber, it is important to note that we cannot completely eliminate this problem. Some customers may still experience signal disruptions.

We recommend that if your key fob battery is running low, you replace it with a new one before installing the carbon fiber shell. A fresh battery will provide a stronger signal, allowing you to enjoy the stylish look of the carbon fiber shell without compromising on performance.
