Recognizing a Dying Lexus IS250 Key Fob Battery

Before you jump to conclusions and order a new battery, it’s crucial to ensure that the battery is the actual culprit. Here are some telltale signs that your 2015 Lexus IS250 key fob battery might need replacing:

Decreased signal range: You find yourself standing closer to your car than usual to lock or unlock it.
Intermittent functionality: The key fob works sometimes but not others, even when standing close to the car.
Multiple button presses required: You need to press the buttons several times before the car responds.
Dashboard warning light: Your Lexus IS250 might display a “Key Fob Battery Low” warning on the dashboard.

If you experience any of these issues, it’s highly likely that your key fob battery is nearing its end and needs replacement.

What Battery Does a 2015 Lexus IS250 Key Fob Take?

The 2015 Lexus IS250 key fob uses a CR2032 battery, a common type of lithium coin battery readily available at most convenience stores, supermarkets, and online retailers. It’s always a good idea to keep a spare battery on hand to avoid any unexpected lockouts.

DIY: Replacing Your Lexus IS250 Key Fob Battery

Replacing the battery in your Lexus IS250 key fob is a straightforward process that you can easily do at home with just a few simple tools. Here’s a step-by-step guide:

Locate the release button: Look for a small button on the back of your key fob. This button releases the emergency key blade.
Release the emergency key blade: Gently slide the release button while simultaneously pulling out the emergency key blade.
Open the key fob casing: Use the tip of the emergency key blade (or a small flat-head screwdriver) to pry open the key fob casing along the seam. Be gentle to avoid damaging the casing.
Remove the old battery: Carefully remove the old CR2032 battery from its slot. Pay attention to its orientation.
Insert the new battery: Place the new CR2032 battery in the slot, ensuring it matches the same orientation as the old one.
Close the key fob casing: Align the two halves of the casing and press firmly until they snap back together securely.
Reinsert the emergency key blade: Slide the emergency key blade back into its slot until it clicks into place.
Test the key fob: Check if all the buttons (lock, unlock, trunk release, panic) are functioning correctly.
