Is your Lexus key fob battery dying, leaving you with that annoying low battery warning? Don’t worry, replacing it is a straightforward task you can easily handle yourself. This guide will walk you through the simple steps to change the battery in your Lexus key fob, saving you time and a trip to the dealership.
What You’ll Need
Before you begin, gather these simple tools:
- A new CR2032 battery: This is the standard battery type for most Lexus key fobs. You can find these at most drugstores, supermarkets, or online retailers.
- A small flathead screwdriver or a thin pry tool: This will be used to gently open the key fob case.
Step-by-Step Guide to Replacing Your Lexus Key Fob Battery
-
Locate the notch on your key fob: Examine your Lexus key fob and find a small notch. This is usually located on the side or bottom of the fob.
-
Insert the tool and gently pry: Carefully insert the flathead screwdriver or pry tool into the notch. Gently twist or pry to separate the two halves of the key fob. Take your time and avoid applying excessive force to prevent damage to the plastic casing.
-
Open the key fob: Once you’ve gently pried the case open, it should split into two pieces. You may need to slide the tool along the seam to fully separate the halves.
-
Remove the old battery: With the key fob open, you’ll see the battery. Note the orientation of the battery (positive side up or down) before removing it. You can usually use your fingertip or the small screwdriver to carefully lift the old battery out of its housing.
-
Insert the new battery: Take your new CR2032 battery and insert it into the battery compartment, making sure to match the correct orientation as the old battery. It should snap into place securely.
-
Reassemble the key fob: Carefully align the two halves of the key fob case and press them firmly back together until they snap closed. Ensure there are no gaps and the case is securely sealed.
-
Test your key fob: Press a button on your key fob to test if the new battery is working. The indicator light on the fob should illuminate, and your Lexus should respond to the commands (locking/unlocking doors, etc.).
Tips for Lexus Key Fob Battery Replacement
- Battery Life: Lexus key fob batteries typically last for 1-2 years, but this can vary depending on usage and storage conditions. If you receive a low battery warning on your dashboard, it’s a good time to replace it.
- Second Key Fob Battery Drain: It’s normal for a key fob battery to slowly drain even when not in use. Keeping a spare key fob with the battery installed in a drawer for extended periods can lead to a dead battery when you need it. Consider storing your spare fob without the battery installed, and insert a new battery when you plan to use it.
- Emergency Start: Even with a completely dead key fob battery, you can still start your Lexus. In most models, you can hold the key fob directly against the engine start button. This allows the car to detect the key chip and start the engine. Consult your Lexus owner’s manual for the exact procedure for your vehicle.
- Battery Brands: While Panasonic is a reputable brand for CR2032 batteries, other quality brands like Duracell, Energizer, and Sony will also work perfectly in your Lexus key fob. Choose a brand you trust for reliable performance.
Conclusion
Replacing your Lexus key fob battery is a simple and cost-effective DIY task. By following these easy steps, you can quickly restore your key fob’s functionality and avoid any inconvenience. Keep a spare CR2032 battery on hand, and you’ll be prepared to handle a dead key fob battery whenever it happens.
