You’re ready to head out for the day, but there’s one problem: your Lexus key fob battery is dead, and your car won’t start. This is a frustrating situation, but don’t worry, you’re not alone! A dead key fob battery is a common problem, and luckily, there are a few things you can do to get your Lexus up and running again.
Understanding Why Your Lexus Won’t Start
Modern Lexus vehicles often utilize a keyless entry system, also known as a smart key system. This means the car “talks” to your key fob wirelessly to unlock the doors and allow you to start the engine. A dead key fob battery means that communication is cut off.
How to Tell if It’s the Key Fob Battery
Here are some signs that your Lexus key fob battery is dead:
- The car doesn’t respond to the key fob: Your Lexus doesn’t unlock when you press the button on the fob.
- You need to be very close to the car: The key fob’s range seems significantly reduced, and it only works when you’re almost touching the car.
- Dashboard warning light: Some Lexus models will display a “Key Not Detected” or similar warning on the dashboard.
What to Do When Your Lexus Key Fob Battery Dies
1. Check Your Owner’s Manual
Your Lexus owner’s manual is your best resource for specific instructions on how to start your car with a dead key fob battery.
2. Use the Hidden Mechanical Key
Most Lexus key fobs have a hidden mechanical key inside. This key is often released with a small button or switch on the fob. Use this key to manually unlock your car door.

3. Find the Key Fob Sensor Location
Your Lexus has a designated spot where it can detect the key fob even with a low battery. This is usually located:
- In the center console
- Underneath the steering column
- In the glove box

Hold the key fob close to this sensor, then try starting your car as usual.
4. Replace the Key Fob Battery
Once you’ve started your car, it’s crucial to replace the dead key fob battery. You can find replacement batteries at most auto parts stores, drugstores, or online. Refer to your owner’s manual for the correct battery type.
