Nothing is more inconvenient than a dead car key fob, especially when it happens unexpectedly. Like any battery-powered device, your Toyota key fob relies on a battery to function, and knowing the correct Toyota Key Fob Battery Size is crucial for a smooth replacement. While these batteries are designed to last, they will eventually need replacing. This guide from your trusted experts at Keyfobx.com will walk you through everything you need to know about your Toyota key fob battery, from identifying the right size to replacing it yourself and understanding when you might need a full key fob replacement.
Identifying Your Toyota Key Fob Battery Size
The most common toyota key fob battery size is the CR2032 3V lithium coin battery. This size powers a wide range of Toyota models. However, to be absolutely certain you’re getting the correct battery, there are a couple of ways to verify:
- Check Your Owner’s Manual: Your Toyota owner’s manual is a treasure trove of information, including the specific battery type required for your key fob. Refer to the index or the section on key fob operation for this detail.
- Examine the Old Battery: Once you open your key fob (instructions below), you can simply take out the old battery. The battery size and type are typically printed directly on the battery itself. Look for markings like “CR2032” or similar codes.
While CR2032 is prevalent, some older or specific Toyota models might use slightly different sizes like CR2025 or CR1632. Always double-check to ensure compatibility. Using the incorrect toyota key fob battery size can lead to poor performance or even damage your key fob.
Step-by-Step Toyota Key Fob Battery Replacement Guide
Replacing your Toyota key fob battery is a straightforward process you can easily do at home. Here’s how:
-
Remove the Physical Key: Locate the small release button on your key fob. It’s usually a metal button situated near the key ring. Press and hold this button while gently pulling out the physical key from the fob.
-
Open the Key Fob Casing: After removing the key, you’ll see a small slot where the key was housed. Insert a small flat-head screwdriver or a thin pry tool into this slot. Gently twist or pry to separate the two halves of the key fob casing. Be careful not to use excessive force to avoid damaging the plastic.
-
Access and Remove the Old Battery: Once opened, you’ll see the internal components, including the circuit board and the battery. The battery is usually held in place by small clips. Gently detach the battery, noting its orientation (+ side up or down) for correct installation of the new battery.
-
Install the New Battery: Take your new toyota key fob battery size (likely CR2032) and install it in the same orientation as the old one. Ensure it’s securely placed in the battery compartment.
-
Reassemble the Key Fob: Carefully snap the two halves of the key fob casing back together until they are firmly closed. Slide the physical key back into its slot until it clicks into place.
-
Test Your Key Fob: Try locking and unlocking your Toyota remotely to ensure the new battery is working correctly.
