Understanding Your Car Key Fob
Before we dive into the process of opening and replacing the battery, it’s essential to understand the different types of car key fobs and their components.

There are several types of car key fobs, including:
- Basic key fobs: These are the most common type of car key fob and usually have a simple design with a single button.
- Smart key fobs: These key fobs have advanced features, such as remote start, keyless entry, and push-button start.
- Keyless entry key fobs: These key fobs have a separate button for unlocking the car and a separate button for locking the car.
Each type of key fob has its own unique design and components, but the process of opening and replacing the battery remains relatively the same.
