Replacing your Lexus Is300 Key Fob Battery is a straightforward task that can save you time and money. Understanding the process and the specifics of your key fob is essential for every Lexus owner. This guide provides a comprehensive overview of the Lexus IS300 key fob battery, covering everything from identification to replacement and even exploring aftermarket options.
Identifying Your Lexus IS300 Key Fob Battery Type
The Lexus IS300 key fob, especially models around 2020, typically uses a CR2032 battery. This is a common 3V lithium coin cell battery widely available in most drugstores, supermarkets, and online retailers. Knowing the correct battery type is the first step to ensuring a smooth replacement process. You can usually confirm the battery type by opening your key fob and checking the markings on the old battery itself if you are unsure.
Step-by-Step Guide to Replacing Your Lexus IS300 Key Fob Battery
Replacing the battery in your Lexus IS300 key fob is a simple procedure you can do at home. Here’s a general step-by-step guide:
- Locate the notch: Most Lexus key fobs have a small notch, usually on the side or bottom.
- Open the fob: Use a small flathead screwdriver or a coin to gently pry open the key fob casing at the notch. Be careful not to scratch the plastic.
- Access the battery: Once open, you’ll see the circuit board and the battery compartment. The CR2032 battery is usually held in place by small clips.
- Remove the old battery: Carefully remove the old battery. You might need to use the tip of a screwdriver to gently nudge it out from under the clips. Take note of the battery’s orientation (+ side up or down) before removing it.
- Insert the new battery: Place the new CR2032 battery into the compartment, ensuring the correct polarity (usually the positive side facing up). It should snap into place.
- Close the fob: Carefully reassemble the key fob casing, pressing firmly until it clicks shut.
- Test: Test the key fob buttons to ensure they are working correctly.
If you encounter any difficulties or are uncomfortable performing this replacement yourself, a local automotive locksmith can assist you.
Understanding Your Lexus IS300 Key Fob Features
The Lexus IS300 smart key fob is more than just a battery case; it’s a sophisticated piece of technology that offers several convenient features:
- Keyless Entry: Allows you to unlock and lock your car doors without physically using a key.
- Push-to-Start Ignition: Enables you to start your vehicle by simply pressing a button on the dashboard while the key fob is inside the car.
- Remote Trunk Release: Opens the trunk with the push of a button on the fob.
- Panic Alarm: Activates the car alarm for emergency situations.
These features rely on a functioning battery, making battery replacement crucial for uninterrupted convenience.
Programming and Replacement Fobs
While battery replacement is simple, replacing the entire key fob, especially if lost or damaged, might require programming. For a 2020 Lexus IS300 Smart Keyless Entry Remote, programming typically needs to be done professionally.
- Aftermarket Options: Aftermarket key fobs, like the 2020 Lexus IS300 Smart Keyless Entry Remote (FCC ID: HYQ14FBA, AG Board 2110) mentioned in the original article, are available and can be a cost-effective alternative to dealership replacements. These often come with an uncut emergency insert key.
- Professional Programming: Aftermarket fobs usually require programming by an automotive locksmith. Dealers may sometimes decline to program aftermarket remotes. Locksmiths are generally equipped to handle the programming of these remotes and can also cut the emergency insert key.
- Compatibility: Ensure the replacement fob is compatible with your vehicle’s model and year. For Lexus IS models from 2014 to 2020 (IS 250, IS 200t, IS 300, IS 350, RC 350, RC 300, RC 200), the specified aftermarket remote (FCC ID: HYQ14FBA) may be compatible, but always verify with the seller or locksmith.
Conclusion
Maintaining your Lexus IS300 key fob battery is a key part of vehicle upkeep. By understanding the battery type (CR2032), knowing how to replace it, and being aware of your key fob’s features, you can ensure your keyless entry system remains reliable. For replacement fobs and programming needs, consider contacting a local automotive locksmith for expert service and potentially more affordable solutions compared to dealership services. Keeping your key fob in good working order ensures seamless access and operation of your Lexus IS300.
