Key with key fob in hand

Wondering how to change the battery in your Lexus key fob? 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 from Town 'N' Country to Brandon, it is time for a Lexus key battery replacement. Read on to learn how with the skilled service team at Lexus of Tampa Bay.

Lexus Key Battery Replacement: Steps

There are a few key tools you’ll need to secure before you begin your Lexus key battery replacement. For starters, you’ll need a flathead screwdriver and a CR2032 lithium battery – which covers every model from the Lexus LX to the Lexus ES. If you can’t find the right Lexus key battery replacement, the parts department here at Lexus of Tampa Bay can help. Once you have all the tools 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 in order 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 Lexus key fob to make sure it works. If it doesn’t, get in touch with our service department for additional advice.

Tips and Tricks for Your Lexus Key Fob Battery

So, how do you get the longest lifespan out of your Lexus key fob battery in Riverview? We recommend turning on the battery-saving mode to avoid draining power when the fob is 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 three feet of electronic appliances with a magnetic field, which includes items like TVs and laptops. This prevents your key fob from receiving waves and draining prematurely.
