What Kind of Battery Does a Lexus Key Fob Take?

Knowing what kind of battery your Lexus key fob takes is crucial for keeping your car accessible. A dead key fob battery can leave you stranded, so understanding how to identify and replace it is essential. This article will guide you through everything you need to know about Lexus key fob batteries, from the specific types to how to change them yourself.

Identifying Your Lexus Key Fob and Its Battery

Lexus has used various key fob designs over the years, and each might require a different battery. Generally, Lexus key fobs use either a CR2032 or a CR2450 battery. Identifying your specific key fob model is the first step to determining the correct battery. Look for any markings or model numbers on the back of the fob. You can also consult your owner’s manual or a Lexus dealership for assistance.

Common Lexus Key Fob Battery Types: CR2032 and CR2450

• CR2032: This is a common battery type for many Lexus key fobs. It’s a 3-volt lithium coin cell battery, readily available at most stores that sell batteries.
• CR2450: Another common battery found in Lexus key fobs, also a 3-volt lithium coin cell, but slightly larger and thicker than the CR2032. This provides a longer lifespan for key fobs with more features.

How to Change Your Lexus Key Fob Battery

Changing the battery in your Lexus key fob is often a simple DIY task. While the exact process might vary slightly depending on the fob model, the general steps are similar. Here’s a typical procedure:

1. Locate the release button or slot: This is usually a small button or slot on the side or back of the key fob.
2. Release the key blade: Most Lexus key fobs have a hidden key blade for emergency access. Release it using the button or lever. You may need to use the key blade itself to pry open the fob casing.
3. Separate the fob halves: Carefully pry open the key fob using a small flathead screwdriver or a similar tool. Avoid using excessive force, as this could damage the casing.
4. Identify the battery: Once the fob is open, you should see the battery. Note the type (CR2032 or CR2450) for replacement.
5. Remove the old battery: Gently pry out the old battery using your screwdriver or fingernail.
6. Install the new battery: Insert the new battery, ensuring the positive (+) side is facing up, just as the old battery was positioned.
7. Reassemble the fob: Align the two halves of the key fob and press them together until they snap shut.
8. Test the key fob: Try locking and unlocking your car to ensure the new battery is working correctly.
