Just like any battery-operated device, your Toyota key fob relies on a small battery to function. Knowing the correct battery size for your Toyota key fob is crucial for ensuring you can replace it efficiently and keep your access seamless. This guide will walk you through everything you need to know about Toyota key fob batteries, from identifying the right size to replacing it yourself.
Identifying Your Toyota Key Fob Battery Size
The most common Battery Size For Toyota Key Fobs is the CR2032 3V lithium coin battery. This size is widely used across various Toyota models and key fob designs. However, to be absolutely certain you’re getting the right battery, there are a couple of ways to confirm:
-
Check the Old Battery: Once you open your key fob (we’ll show you how shortly), you can simply look at the markings on the existing battery. It will clearly state the battery type, often as “CR2032”.
-
Consult Your Owner’s Manual: Your Toyota owner’s manual is a treasure trove of information. Look up the section on key fob maintenance or battery replacement, and it should specify the correct battery size for your specific model and year.
-
Online Resources: Websites like ours, keyfobprog.com, are dedicated to providing information on key fobs. You can often find model-specific battery information through online searches or by browsing our site.

While CR2032 is the most prevalent, it’s always best to double-check to avoid any issues. Using the incorrect battery size might lead to poor contact or even damage your key fob.
Step-by-Step Toyota Key Fob Battery Replacement
Replacing your Toyota key fob battery is a straightforward process you can typically handle yourself in just a few minutes. Here’s a simple guide based on the standard procedure:
-
Remove the Mechanical Key: Locate the small release button on your key fob. Press and hold this button while gently pulling out the mechanical key. This key is a backup access method and needs to be removed to open the fob casing.
-
Open the Key Fob Casing: After removing the key, you’ll see a small slot where the key was inserted. Use a small flathead screwdriver or a similar thin, flat tool. Carefully insert the tool into the slot and gently twist to pry open the two halves of the key fob casing. Be gentle to avoid damaging the plastic.
-
Access and Replace the Battery: Once open, you’ll see the internal components, including the battery. It’s usually held in place by small clips. Carefully remove the old battery, noting the orientation (+ side up). Insert the new CR2032 battery (or the size specified for your fob) in the same orientation.
-
Reassemble the Key Fob: Carefully snap the two halves of the key fob casing back together until they are securely closed. Replace the mechanical key back into its slot until it clicks into place.
-
Test Your Key Fob: Try locking and unlocking your car doors with the buttons on the fob to ensure the new battery is working correctly.

When to Consider Full Key Fob Replacement
While battery replacement solves most key fob issues related to power, sometimes a full Toyota key fob replacement is necessary. This might be the case if:
- Lost or Damaged Fob: If you’ve lost your key fob or it’s been severely damaged (water damage, crushed, etc.), a replacement is unavoidable.
- Malfunctioning Buttons: If buttons are unresponsive even after battery replacement, the internal circuitry might be faulty.
- Range Issues: Consistently poor operating range, even with a new battery, could indicate a deeper problem with the fob’s transmitter.
If you need a full key fob replacement, contacting a Toyota dealership or a certified automotive locksmith is recommended. They can provide a new key fob programmed to work with your vehicle’s security system. Remember to inquire about any parts specials or discounts that might be available to reduce the cost.
