First and foremost, the compatibility of the Aichiyu Flip Remote Key Fob is impressive. It is specifically designed to work with the FCC ID SY5JFRGE04 and P/N 95430-D4010.

When I first encountered the Kia Optima, I quickly realized how essential the key fob is to my daily driving experience. This small device not only unlocks my car but also enhances my overall convenience. Understanding the different types of key fobs available for the Kia Optima helped me make an informed decision when it was time to purchase a replacement.

Types of Key Fobs

There are several types of key fobs that I discovered while researching. The traditional key fob operates using a battery and communicates wirelessly with my car.

Battery life was another important factor for me. I wanted a key fob that would last a long time without needing frequent battery changes. During my search, I found that some key fobs have longer battery lives than others. I also looked into how easy it was to replace the battery when the time came.
