Understanding Your Tesla Key Fob
Before diving into the battery replacement process, it’s essential to familiarize yourself with the key fob’s anatomy. Tesla key fobs typically consist of the following components:
- Battery Compartment: This is where the CR2032 lithium battery resides, providing the power for the fob’s functions.
- Key Button: Used to unlock and lock the vehicle doors.
- Trunk Button: Opens the trunk or frunk (front trunk).
- Power Button: Used to wake up the key fob and activate its features.
- Tesla Logo: A prominent indicator of your Tesla ownership.
The specific layout and design may vary slightly depending on the model year and trim level of your Tesla. However, the fundamental components remain consistent.
Gathering Your Tools and Materials
Before you begin the battery replacement process, ensure you have the necessary tools and materials on hand:
- CR2032 Lithium Battery: This is the standard battery type used in Tesla key fobs. You can purchase them online or at most electronics stores.
- Small Flathead Screwdriver: This will be used to pry open the key fob’s battery compartment.
- Soft Cloth: Use this to clean the battery contacts before inserting the new battery.
Having these items readily available will streamline the process and prevent any unnecessary delays.

Align the positive (+) and negative (-) terminals of the new CR2032 battery with the corresponding contacts in the compartment. Gently press the battery into place until it sits securely.
Step 6: Reassemble the Key Fob
