Your Tesla key fob is more than just a remote control; it’s your digital passport to your electric vehicle. It unlocks your doors, starts your engine, and even allows you to control various vehicle functions remotely. But what happens when this essential device starts acting up? A common culprit is a dying battery. Fortunately, replacing a Tesla key fob battery is a relatively straightforward process that can be done at home, saving you time and money. This comprehensive guide will walk you through every step, empowering you to keep your Tesla running smoothly.
Understanding Your Tesla Key Fob
Before diving into the battery replacement process, it’s crucial to understand the different components of your Tesla key fob. The key fob typically consists of a plastic casing, a circuit board, a battery, an antenna, and a few buttons. The battery, usually a small, coin-shaped lithium-ion cell, provides the power necessary for all these components to function.
Types of Tesla Key Fobs
Tesla offers different key fob models, each with its own unique design and features. Some common types include:
- Model S and Model X Key Fob: These key fobs are typically larger and feature a more traditional key design.
- Model 3 and Model Y Key Fob: These key fobs are sleeker and more compact, resembling a credit card.
Regardless of the model, the battery replacement process remains largely the same.
Gathering Your Tools and Materials
Before you begin, make sure you have everything you need. Here’s a list of essential tools and materials:
- New Battery: Ensure you purchase a compatible battery for your specific Tesla key fob model. You can find these online or at automotive parts stores.
- Small Phillips Head Screwdriver: This is used to remove the key fob’s back cover.
- Optional: A small plastic pry tool can be helpful for gently lifting the key fob’s cover.

Step 5: Reassemble the Key Fob
Replace the back cover and screw it back into place. Make sure the screw is tightened securely but avoid overtightening, which could damage the key fob.
Step 6: Test the Key Fob
Now, it’s time to test your newly replaced key fob. Approach your Tesla and try unlocking the doors, starting the engine, and using other key fob functions. If everything works as expected, you’ve successfully replaced the battery!
