How to Change the Battery in a Lexus Key Fob
If the features of your Lexus key fob aren’t working as well as they used to work, you may be due for Lexus key battery replacement. These batteries generally last 1-2 years, if not longer, and learning how to change the battery in a Lexus key fob only takes a moment of your time! Don’t let the loss of power keep you from enjoying your trips through Ooltewah and Lookout Mountain.
What Kind of Battery Does My Lexus Key Fob Take?
Like the vast majority of modern vehicles, the Lexus key fob battery is a type CR2032. If you’re near Chattanooga, you can pick up the correct battery at our parts department or at another local hardware store.
Lexus Key Battery Replacement: Step-by-Step
Once you’ve got the fresh battery and you’ve picked up a flathead screwdriver, you’re ready to begin:
- Remove the manual emergency key that is stored inside of the key fob. A small button on the fob itself should release it.
- Once the emergency key has been loosed, set it aside and use the flathead screwdriver to separate the top and bottom halves of your fob casing.
- Depending on how you open it, there may be a small electronic console that you need to remove before reaching the battery.
- Remove the old battery and place the new battery in its place with the positive side facing upwards.
- Carefully return everything to its place, and you’re good to go!
If you’re still having problems after you’ve finished the Lexus key fob battery replacement process, it may be that you actually need a new fob! Should that be the case, our parts department would be happy to order a replacement.
How to Extend the Life of Your Lexus Key Battery
If you hold down the LOCK button on your Lexus key fob and press the UNLOCK button twice, you’ll enter a battery-saving mode that stops the key from receiving radio waves.
Please note that this will prevent the use of features like Smart Access and push-button start, but all you need to do is press a single button on the key fob to return it to its normal state. Check out our list of service tips and tricks for more advice!
