Lexus Key Battery Low: When to Replace Battery

While your key battery should last you about 1-2 years, there are obvious signs that indicate when a Lexus key battery is low on power. You may receive an aural low battery alert, but there are also more subtle indicators:

  • There is no longer an LED indicator light.
  • Push Button start, which is based upon proximity to the key fob, doesn’t work
  • Smart Access doesn’t work
  • Your key fob no longer has “the range.”

How to Change the Lexus Key Fob Battery: Step-by-Step Instructions

Your Lexus key fob uses a CR2032 lithium battery — a flat, round battery. The simplest way to make sure you’ve got the right one is ordering a key fob battery online from Wilde Lexus Sarasota, but many Venice area parts or hardware/electronics store should carry them. Here’s how to change the battery in a Lexus key fob:

  • Step 1: Dry your hands so as to eliminate the possibility of moisture-caused battery rust.
  • Step 2: Push the release button on the side of the fob so the key comes out.
  • Step 3: Use a flathead screwdriver to pop open the key fob cover. Pro tip: putting tape on the tip of the screwdriver will prevent scratching!
  • Step 4: Remove battery, first removing the key module if it’s there.
  • Step 5: Battery in, plus side up. Then put the key fob back together!

How To Change the Battery in Lexus Key Fob: Battery Saving Mode

You might be surprised to find out that your key fob comes with a battery saver mode! Like a car battery, there are proactive steps you can take to save power. Here’s how to access that mode and other tips for battery saving.

  • Hold down the lock button then press the unlock button twice. Your indicator will flash four times, meaning that you’re in battery-saving mode.
  • You can also save battery power by keeping your key fob more than 3 feet away from electronics that produce magnetic fields (laptops, cell phones, TVs, battery chargers, induction cookers, table lamps).

Benefits of Key Fob for Your Lexus Vehicle

Having to learn how to change the battery in your Lexus key fob can seem like a bit of a hassle, but you can rest assured knowing that the advantages of owning a key fob for your Lexus vehicle far outweigh the negatives. The key fob is a technological innovation that provides countless benefits compared to its traditional key predecessor. Some of those state-of-the-art benefits include:

  • Auto-Lock Systems: If you’re like most drivers in Bradenton, you’ve probably looked over your shoulder in a parking lot to ensure that you’re Lexus car is secure. Why not avoid this inconvenience with keyless technology, as most key fobs allow the vehicle to lock itself automatically once the key is out of range. A smart and efficient way to keep your car and your cargo inside safe when you’re not around. Just make sure to keep an eye out for when the Lexus key battery’s low!
  • Easy Accessibility: Instead of fumbling around with keys after a long day at work or school, wouldn’t you rather just be nearby your Lexus car for the doors to automatically unlock? The Lexus key fob allows you to do just that. Remote keyless entry is incredibly helpful if you’re lugging bags from the grocery store to your vehicle, or busily getting your children ready for school – advantages that are well worth a routine battery change in your Lexus key fob.
  • Theft Security:  Keyless vehicles require a unique code to start the engine, a code that only your specific Lexus key fob can provide. Through the use of radio frequencies that only your car can recognize, the system authorizes the use of ignition and other car features. Knowing how to change the battery in your Lexus key fob is critical in keeping your remote device functional, maintaining the protective mechanisms that your fob is synced up to, and helping secure your vehicle from criminals.
