A dead key fob battery can be a major inconvenience, leaving you stranded and unable to unlock your Lexus. Thankfully, replacing the battery is a quick and easy process that anyone can do at home with a few simple tools. This guide will walk you through the steps to replace the battery in your Lexus key fob, get you back on the road, and help you avoid a costly trip to the dealership.
What You’ll Need to Change Your Lexus Key Fob Battery
Before you begin, gather the following items:
- A new CR2032 battery (This is the most common type of battery for Lexus key fobs, but it’s always best to verify with your owner’s manual)
- A small flat-head screwdriver or a plastic pry tool
- Your Lexus key fob
Locating the Battery Compartment
Lexus key fobs have a sleek and integrated design, but accessing the battery compartment is still quite simple. Most Lexus key fobs have a small release button or slot on the back.
- Turn your Lexus key fob over to examine the back.
- Look for a small, recessed button or a narrow slot. This is the release for the battery compartment cover.
Opening the Key Fob
Once you’ve located the battery compartment release, you can proceed with the following steps:
- If your key fob has a small button, press it firmly. If it has a slot, insert your flat-head screwdriver or plastic pry tool gently into the slot and apply slight pressure to release the cover.
- The battery compartment cover should pop open or slide out, revealing the battery inside.
Replacing the Battery
With the battery compartment open, you can now easily replace the old battery.
- Carefully remove the old CR2032 battery. Note the orientation of the positive (+) and negative (-) sides of the battery.
- Align the positive (+) side of the new battery with the positive (+) marking inside the compartment.
- Gently press the new battery into place. You should hear a slight click when it’s secure.
Pro Tip: Avoid touching the top and bottom surfaces of the new battery, as this can transfer oils from your skin and reduce the battery’s lifespan.
Reassembling the Key Fob and Testing
Once the new battery is installed, it’s time to put your key fob back together and ensure it’s functioning correctly.
- Align the battery compartment cover with the key fob housing.
- Gently press down on the cover until it snaps securely back into place.
- Test all the buttons on your Lexus key fob (lock, unlock, panic) to make sure they are working properly.
If the buttons are not responding, double-check that the battery is correctly installed and that the terminals are clean.
Still Having Trouble?
While replacing a Lexus key fob battery is typically straightforward, there are instances where you might encounter issues or require additional assistance. If you’ve followed these steps and are still experiencing problems with your Lexus key fob, consider the following:
- Consult your owner’s manual: Your Lexus owner’s manual provides model-specific instructions and troubleshooting tips for your key fob.
- Check for other issues: If replacing the battery doesn’t resolve the problem, there might be other underlying issues with your key fob, such as a faulty button or a synchronization problem.
- Contact your local Lexus dealer: For further assistance or complex issues, reach out to your authorized Lexus dealer for expert diagnosis and repair.
Conclusion
Changing the battery in your Lexus key fob is a simple DIY task that can save you time and money. By following these steps and keeping a spare battery handy, you can ensure that a dead key fob never leaves you stranded. Remember to refer to your owner’s manual for model-specific instructions and always prioritize safety when handling small electronic components.
