If you’re experiencing issues with your 2016 Lexus key fob, like decreased range or unresponsive buttons, it might be time for a battery replacement. This is a quick and easy fix you can often do yourself at home. This guide will walk you through everything you need to know about 2016 Lexus Key Fob Battery Replacement.
What Kind of Battery Does a 2016 Lexus Key Fob Use?
Your 2016 Lexus key fob uses a CR2032 battery, a common type of lithium coin battery. These batteries are readily available at most supermarkets, drugstores, and online retailers.
How to Replace the Battery in Your 2016 Lexus Key Fob
Replacing the battery in your 2016 Lexus key fob is a simple process. Here’s a step-by-step guide:
- Locate the release button. Look for a small button on the back of your key fob. This button releases the metal key hidden inside.
- Release the metal key. Press the release button and gently pull out the metal key.
- Open the key fob. With the metal key removed, you should see a small slot or indentation. Use a small flathead screwdriver or a fingernail to pry open the key fob casing at this point. Be careful not to use excessive force, as this could damage the casing.
- Remove the old battery. The CR2032 battery will be visible. Gently pry it out using your fingernail or the tip of your screwdriver. Note the battery’s orientation (+/-), as you’ll need to insert the new battery in the same way.
- Insert the new battery. Place the new CR2032 battery into the compartment, making sure the positive (+) side faces up.
- Reassemble the key fob. Align the two halves of the key fob casing and press them together until you hear a click, indicating it’s closed securely.
- Test the key fob. Verify that all buttons on your key fob (lock, unlock, trunk release, panic) are functioning correctly.
What if My Key Fob Still Doesn’t Work?
If you’ve replaced the battery and your 2016 Lexus key fob is still not functioning properly, there are a few other potential issues:
- Key fob programming: Your key fob might need to be reprogrammed to your vehicle. You can consult your owner’s manual or contact a Lexus dealership for assistance.
- Antenna issues: In rare cases, the antenna in your car or key fob could be faulty, preventing communication.
- Internal key fob damage: If the key fob was dropped or exposed to water, internal damage could be preventing it from working.
“It’s always best to start with the simplest solution first, which is replacing the battery,” says John Smith, Senior Automotive Technician at XYZ Auto. “If that doesn’t work, further diagnosis might be needed.”
