Is your Tesla Model X displaying a low key fob battery warning? Don’t worry, replacing the battery in your key fob is a simple task you can do yourself in just a few minutes. This guide will walk you through each step of the process, ensuring you get your key fob back in working order quickly and efficiently.
When your Model X Key Fob Battery starts to run low, you’ll typically see a message appear on your instrument panel alerting you to the issue. Tesla recommends replacing the battery in all your key fobs at the same time to ensure consistent performance and avoid future inconveniences. The battery life generally lasts around a year with normal use, so proactive replacement can save you from being caught off guard.
What You’ll Need
Before you begin, gather these simple tools and supplies:
- A new CR2354 battery. Tesla recommends using Panasonic CR2354 batteries, which are widely available online, at supermarkets, and drug stores.
- A small flat-bladed tool or even just your fingernail will work to open the key fob casing.
Step-by-Step Guide to Replacing Your Model X Key Fob Battery
Follow these detailed steps to replace your Model X key fob battery:
Step 1: Open the Key Fob Casing
-
Place your Model X key fob button-side down on a soft, clean surface to protect it from scratches.
-
Locate the bottom cover of the key fob.

-
Use a small flat-bladed tool or your fingernail to gently pry open the bottom cover. Insert the tool or your fingernail into the seam where the bottom cover meets the rest of the key fob and carefully release the cover.
Note: If you have a lanyard attached, you can use it to your advantage. Place your thumb on the “X” on the bottom cover and pull the lanyard firmly towards you. This action will push the key fob off its cover. Alternatively, you can use a small flat-bladed tool, fingernail, or the Tesla-provided tool against the lanyard cord to pry the cover open.
Step 2: Remove the Old Battery
-
Once the bottom cover is removed, you’ll see the battery.

Carefully remove the old battery. It is held in place by retaining clips. Gently release the battery from these clips at an angle to avoid damaging the contacts.
Step 3: Insert the New Battery
-
Take your new CR2354 battery and ensure it is the correct type.

-
Insert the new battery with the ‘+’ side facing upwards.
-
The battery compartment is designed for a snug fit. Slide the battery into position at an angle, directing it towards the positive contact (the contact near the center of the key fob).
-
Press down firmly on the opposite side of the battery to secure it in place. Ensure it is held firmly by the retaining clips.
CAUTION: When inserting the new battery, make sure it presses against the spring on the positive contact. Do not force the battery straight down vertically onto the contact, as this can cause damage.
Note: Before fitting the new battery, wipe it clean to remove any fingerprints, and avoid touching the flat surfaces. Fingerprints can reduce battery life.
Step 4: Close the Key Fob Casing
-
Hold the bottom cover at an angle.
-
Align the tabs on the widest side of the cover with the corresponding slots on the key fob.
-
Press the cover firmly onto the key fob until you hear it snap securely into place.

Conclusion
Replacing the battery in your Model X key fob is a straightforward maintenance task. By following these simple steps, you can ensure your key fob remains powered and functional.
