Is your 2014 Lexus ES 350 key fob acting a little sluggish? Before you schedule a pricey trip to the dealership, consider this: it might just be a dead battery. Replacing the battery in your key fob is a simple task that you can easily do yourself at home. Let’s walk through the steps together.
Identifying a Dying Key Fob Battery
How can you tell if your key fob battery is the culprit? Look out for these telltale signs:
- Decreased Range: Are you having to stand closer and closer to your car to get it to lock or unlock?
- Delayed Response: Is there a noticeable lag between pressing a button on your key fob and your car responding?
- Dimming Lights: If your key fob has a light, does it appear dimmer than usual?
- Intermittent Functioning: Does your key fob sometimes work and sometimes not?
If any of these sound familiar, your key fob battery is likely due for a replacement.
What You’ll Need
Don’t worry, you won’t need a mechanic’s toolkit for this job. Here’s all you need:
- A New CR2032 Battery: You can find these at most hardware stores, electronics retailers, and even online.
- A Small Flathead Screwdriver: A standard eyeglasses screwdriver works perfectly.
Replacing the Battery: Step-by-Step
Now for the easy part. Follow these steps to swap out that old battery:
- Locate the Release Button: On the back of your key fob, you’ll find a small button. Press it to release the metal key.
- Open the Key Fob: Use your flathead screwdriver to carefully pry open the key fob case. Start at the seam where you released the metal key. You might need to apply a little gentle pressure.
- Remove the Old Battery: The old battery should be visible. Gently remove it using your fingernail or the flathead screwdriver.
- Install the New Battery: Place the new CR2032 battery into the compartment, ensuring the positive (+) side is facing up, just like the old one.
- Reassemble the Key Fob: Carefully snap the two halves of the key fob casing back together.
- Reinsert the Metal Key: Slide the metal key back into its slot until you hear a click.
- Test Your Key Fob: Try locking and unlocking your car doors to make sure the new battery is working correctly.
Still Having Trouble?
If you’ve replaced the battery and your key fob is still acting up, there might be another issue at play. In such cases, it’s best to consult with a qualified automotive locksmith or your Lexus dealership for further diagnosis and assistance.
Expert Tip from John Miller, Certified Automotive Locksmith: “Remember to dispose of your old key fob batteries properly. They contain hazardous materials and should never be thrown away in the regular trash. Check with your local recycling center for safe disposal options.”
