Man opening car with key fob

Are you having trouble with your Lexus key fob in Cerritos? You may be in need of a Lexus key battery replacement. The battery typically lasts between one and two years of regular use, and when you’re running low on charge, you’ll get a few warning signs, such as a low-battery alert sound when the engine is stopped, decreased range on proximity detector, and a dimmer LED indicator light. If you notice any of these symptoms while driving through Long Beach, it’s time to change your Lexus key fob battery.


Steps of Lexus Key Battery Replacement

Before you start diving into how to change a battery in a Lexus key fob, it’s important to grab a few tools. You’ll need a flathead screwdriver and a CR2032 lithium battery – which covers every model from the Lexus RX to the Lexus ES. If you can’t find the right Lexus key battery replacement, the parts department of Lexus of Cerritos can help. Once you have everything you need, simply follow these steps:

  1. Make sure your hands are completely dry. Introducing moisture to your key fob can cause your new battery to rust.
  2. Push the release button on the side of the fob and remove the mechanical key.
  3. Use the screwdriver to open the key fob cover. Wrap the tip of the screwdriver with tape if you’d like to avoid scratches.
  4. If you notice an electronic key module, remove it and then remove the old battery with the screwdriver.
  5. Install the new battery with the + side facing upward. Put the electronic key model back on.
  6. Snap the key fob cover back in place.

After you’ve completed these steps, test your key fob to make sure it works. If it doesn’t, get in touch with us at the service department for additional advice.


Tips and Tricks for Your Lexus Key Fob Battery

So, just how do you get the longest lifespan out of your Lexus key fob battery in Torrance? We recommend turning on the battery-saving mode to avoid draining power when not in use.

  • Hold down the LOCK button while tapping the UNLOCK button two times.
  • Watch for the electronic indicator to flash four times. This means you are now in battery-saving mode.
  • Press any of the key fob buttons to access push-button start and Smart Access again.

It’s also a good idea to avoid placing your fob within 3 feet of electronic appliances with a magnetic field, which includes things like TVs and laptops. This prevents your key fob from receiving waves and draining the battery prematurely.
