If you drive a Lexus, you know that the key fob is essential for accessing and starting your vehicle. But like all key fobs, the battery can eventually die, leaving you stranded. Don’t panic! Replacing the battery in your Lexus key fob is a quick and easy process you can do yourself. This guide will walk you through the steps, ensuring you’re back on the road in no time.
What You’ll Need to Replace Your Lexus Key Fob Battery
Before you begin, gather the following items:
- A small flat-head screwdriver: This will be used to pry open the key fob.
- A new CR2032 battery: This is the most common type of battery used in Lexus key fobs.
Pro Tip from John Miller, Senior Automotive Technician at CarDiagTech Workshop: “Always make sure you’re purchasing a high-quality CR2032 battery from a reputable brand. Using a cheap battery can lead to shorter lifespan and even damage to your key fob.”
Steps to Replace the Battery in Your Lexus Key Fob
Here’s a step-by-step guide to changing your Lexus key fob battery:
- Locate the release button: On the back of your Lexus key fob, you’ll find a small, sliding release button.
- Release the valet key: Slide the release button while gently pulling out the valet key. This key is used for emergencies and manual door unlocking.
- Open the key fob: Using the flat-head screwdriver, carefully insert it into the slot where you removed the valet key. Gently pry open the two halves of the key fob. You might hear a slight click as it opens.
- Remove the old battery: Inside the key fob, you’ll see the CR2032 battery. Carefully remove it, noting the orientation (+/-).
- Insert the new battery: Place the new battery in the same orientation as the old one, ensuring the positive (+) side is facing up.
- Reassemble the key fob: Align the two halves of the key fob and press them together until they snap shut.
- Test your key fob: Ensure the new battery is working by locking and unlocking your car doors using the key fob buttons.
Important Note: Avoid touching the battery terminals with your fingers. This can reduce battery life. If you accidentally touch them, wipe them with a clean, dry cloth before inserting the battery into the key fob.
Troubleshooting: What if My Key Fob Still Doesn’t Work?
If you’ve replaced the battery and your key fob is still unresponsive, don’t worry. Here are a few things you can check:
- Battery Orientation: Double-check that the new battery is inserted correctly with the positive (+) side facing up.
- Battery Contacts: Inspect the battery contacts inside the key fob for any dirt or corrosion. If you see any, gently clean them with a cotton swab dipped in rubbing alcohol.
- Key Fob Programming: In rare cases, you might need to reprogram your key fob after changing the battery. Refer to your Lexus owner’s manual for instructions on how to do this.
“Remember, attempting to reprogram your key fob yourself can be tricky. If you’re unsure, it’s always best to consult with a qualified Lexus technician to avoid any potential issues,” advises John Miller.
