We understand the frustration of a malfunctioning key fob, especially when it leaves you stranded. This comprehensive guide will walk you through everything you need to know about your Lexus IS250 key fob battery, from identifying the correct size to replacing it yourself.
Understanding Your Lexus IS250 Key Fob
The key fob is a sophisticated piece of technology that provides convenience and security. It’s responsible for locking and unlocking your car, activating the alarm system, and even starting the engine remotely. Like any electronic device, the key fob relies on a battery to power its functions. Over time, this battery can drain, leading to a weakened signal or a complete loss of functionality.
Common Signs of a Dying Key Fob Battery
Recognizing the signs of a dying key fob battery can save you a lot of hassle down the road. Here are some telltale signs to watch out for:
- Decreased Range: You find yourself having to stand closer to your car for the key fob to work.
- Intermittent Functionality: The key fob works sporadically, sometimes requiring multiple button presses.
- Warning Light: Some Lexus IS250 models display a warning light on the dashboard, indicating a low key fob battery.
Determining the Correct Lexus IS250 Key Fob Battery Size
Using the correct battery size for your Lexus IS250 key fob is crucial. An ill-fitting battery can cause damage or lead to improper functionality.
The Lexus IS250 typically uses a CR2032 battery for the key fob.
This small, coin-shaped battery is widely available at most electronic stores, auto parts stores, and even some convenience stores.
Important Note:
While the CR2032 is the most common battery size for the Lexus IS250 key fob, it’s always recommended to double-check your owner’s manual. The manual will provide the most accurate information specific to your vehicle’s year and model.

Replacing the key fob battery is a straightforward process that most car owners can handle themselves. Here’s a step-by-step guide:
- Gather Your Materials: You’ll need a new CR2032 battery and a small flat-head screwdriver.
- Locate the Battery Compartment: The battery compartment is usually located on the back of the key fob. It might be a small slide-out compartment or secured with a small screw.
