In the realm of modern automotive technology, Tesla vehicles have carved a niche for themselves with their sleek design, impressive performance, and innovative features. However, even these technologically advanced vehicles rely on seemingly simple components like key fobs to unlock their doors and start their engines. While Tesla key fobs are known for their durability and reliability, their batteries, like all batteries, have a finite lifespan. When the battery in your Tesla key fob starts to weaken, it can be a frustrating experience, leaving you stranded or unable to access your vehicle. Fortunately, changing the battery in a Tesla key fob is a relatively straightforward process that can be accomplished with a few simple tools and a bit of patience.
This comprehensive guide will walk you through the step-by-step process of replacing the battery in your Tesla key fob, empowering you to tackle this common issue with confidence. Whether you’re a seasoned Tesla owner or a new enthusiast, understanding how to change your key fob battery can save you time, money, and potential headaches in the future.
Understanding Your Tesla Key Fob
Before diving into the battery replacement process, it’s essential to familiarize yourself with the components of your Tesla key fob. Tesla key fobs typically consist of the following:
- Battery compartment: This is the area where the battery is housed. It is usually located on the back of the key fob and is secured with a small screw or a snap-on cover.
- Keyless entry button: This button allows you to lock and unlock your Tesla remotely.
- Trunk release button: This button unlocks the trunk of your Tesla.
- Panic button: This button activates the car’s horn and hazard lights.
- Charging indicator light: This light indicates the status of the key fob’s battery.
Tesla key fobs are designed to be water-resistant and durable, but the battery compartment is a vulnerable area that can be susceptible to damage if not handled carefully.
Gathering Your Tools
To successfully replace the battery in your Tesla key fob, you’ll need a few essential tools:
- Small Phillips head screwdriver: This screwdriver is used to remove the screw securing the battery compartment.
- New battery: Make sure to purchase a battery that is compatible with your Tesla key fob model. The specific battery type and model number can be found in your owner’s manual or online.
- Small flathead screwdriver (optional): This tool can be helpful for prying open the battery compartment if it is secured with a snap-on cover.
It’s always a good idea to have a backup key fob available in case you encounter any difficulties during the battery replacement process.

Step 1: Locate the Battery Compartment
The battery compartment is typically located on the back of your Tesla key fob. Examine the back of the key fob for a small indentation or a seam that indicates the location of the compartment.
Step 2: Open the Battery Compartment
Depending on your Tesla key fob model, the battery compartment may be secured with either a small screw or a snap-on cover. If it’s secured with a screw, use the small Phillips head screwdriver to carefully remove the screw. If it’s secured with a snap-on cover, gently pry it open using a small flathead screwdriver or your fingernails.
Step 3: Remove the Old Battery
Once the battery compartment is open, you’ll see the old battery. Carefully remove the old battery from its holder. Note the positive (+) and negative (-) terminals of the battery to ensure that you install the new battery correctly.
Step 4: Install the New Battery
Insert the new battery into the holder, matching the positive (+) and negative (-) terminals with the corresponding markings in the battery compartment. Make sure the battery is securely seated in its holder.
Step 5: Close the Battery Compartment
Gently snap the battery compartment cover back into place, or replace the screw that secures it. Ensure that the cover is securely closed to prevent water or dust from entering the compartment. (See Also: How Big Is The Battery On A Tesla? Unveiled)
Testing Your Key Fob
After replacing the battery, it’s essential to test your key fob to ensure that it’s functioning correctly. Press the keyless entry button to lock and unlock your Tesla.

Troubleshooting Tips
If you encounter any issues during the battery replacement process, here are a few troubleshooting tips:
- Double-check the battery polarity: Make sure that the positive (+) and negative (-) terminals of the new battery are correctly aligned with the markings in the battery compartment.
- Ensure the battery is fully seated: The battery should be securely inserted into its holder. If it’s not fully seated, it may not make proper contact and could result in malfunctioning.
- Try a different battery: If you’re still experiencing issues, try using a different new battery to rule out a defective battery.
- Contact Tesla service: If you’re unable to resolve the issue on your own, contact Tesla service for assistance.
