Do you like being hands-on with your Lexus and solving problems independently? Changing your Lexus key fob battery is an easy do-it-yourself project, requiring just a screwdriver (or small coin) and a few easy steps. Check out the following helpful tips and tricks to replace your key fob battery and discover ways to save battery power.
Common Signs Your Lexus Key Fob Battery Needs Replacing
Is your Lexus key fob unresponsive? The battery may need replacing if it’s not working as it did. Be on the lookout for the following indicators that a new battery is needed:
- The key fob only works close to your Lexus, meaning the detection area is smaller.
- A low-battery alert sounds in your Lexus’ cabin when the engine is stopped.
- Nothing happens when you push different buttons on the key fob.
- The LED indicator light on your Lexus key fob no longer turns on.
- Your Lexus’ push button start or smart access system no longer functions.
How To Change Your Lexus Key Fob Battery in Four Easy Steps
Before you start the battery replacement process, ensure your hands are washed and dried to prevent battery rust caused by moisture in the key fob. The tool you need to replace your Lexus key fob battery is a flathead screwdriver or a small coin; you’ll also need a replacement battery. You can refer to your vehicle’s owners manual for specific instructions if required.
Remember to be gentle at each step to prevent cracking the key fob or causing other internal or external damage. While the exact key fob battery replacement instructions vary from model to model, you can follow these steps to do it yourself:
- Push the release button on the side of the key fob to slide out and remove the metal mechanical key stored inside.
- Once the mechanical key is removed, open and remove the key fob cover. You can open it by inserting a flathead screwdriver or a small coin into the small indentation on the cover. Twist your tool to pop the cover open.
- You can access the old battery once you have removed the Lexus key fob cover. If an electronic key module is covering it, remove this piece first. Next, use the flathead screwdriver or small coin to remove the key fob’s dead battery.
- Replace the old battery with a new one. Ensure you insert the new battery with the “+” terminal facing up. Replace the electronic key module if there is one. Last, put the key fob cover back on and slide the mechanical key back into the key fob.
Test the buttons on your Lexus key fob to ensure the installation was correct. If, for some reason, the buttons still don’t work or the LED indicator light doesn’t come on, bring your key fob to a certified Lexus dealer. Our professional parts and service team will use the utmost care to remedy any issue you experience.
What Kind of Battery Does a Lexus Key Fob Need?
The battery type needed for your Lexus key fob depends on your vehicle’s model and year. Lexus vehicles from 2010 and newer typically use CR1632 and CR1616 Panasonic batteries. Reference your Lexus owners manual for the key fob’s particular battery size. If you’re still unsure of what size battery you need, contact our parts department at Lexus Longo for expert assistance. We’ll set you up with what you need or order replacement parts.
How Long Does a Lexus Key Fob Battery Last?
A Lexus key fob battery should last between one and two years. If you purchase aftermarket batteries, you risk having a shorter battery life and will need a replacement sooner than expected. That’s why it’s best to buy genuine Lexus replacement parts. Purchasing replacement parts from an authorized Lexus dealer ensures the best quality and long-lasting durability.
Ways To Save Your Lexus Key Fob’s Battery
Did you know that your Lexus key fob has a power-saving mode? All Lexus models paired with a smart key have a power-saving mode to conserve battery life. It shuts off the key fob when not in use, helping it save battery power. Press the Lock button on your Lexus key fob to engage the power-saving mode, hold it down, and press the Unlock button twice. The LED indicator light will blink four times, indicating the power-saving mode is on.
Smart key or remote access is disabled when the power-saving mode is on. Press any button on your Lexus key fob to disengage from power-saving mode. Another helpful tip to prolong the life of your key fob’s battery is to avoid placing it near electrical appliances such as TVs, laptops, cellphones, and battery chargers. The magnetic fields produced by these appliances can drain your Lexus key fob’s battery.
Accessorize Your Lexus Key Fob
Accessorizing your Lexus isn’t limited to the vehicle itself. You can enhance the look of your key fob while protecting it at the same time. Purchase Lexus key gloves made from durable synthetic leather designed to fit your key fob perfectly and keep it clean and safe from dents or scratches. These special key gloves come in colors such as brown or black, with bronze, silver, or red stitching. They feature an embossed Lexus logo on the back and easy access to the mechanical key.
