If you’re having trouble starting your 2011 Lexus RX 350 with the key fob, you’re not alone. This is a common issue with many possible causes, ranging from simple battery problems to more complex electronic malfunctions. This comprehensive guide will walk you through the most likely reasons your key fob isn’t working and how to get your Lexus RX 350 started again.
Common Reasons Your Key Fob Won’t Start Your Car
There are several reasons why your 2011 Lexus RX 350 might not respond to the key fob. Here are some of the most common culprits:
1. Dead Key Fob Battery
The most common reason your key fob might not work is a dead battery. Key fob batteries typically last 3-4 years, depending on usage and environmental factors.
How to check: Most key fobs have a small button that releases a hidden key. Use this key to open your car door manually. If the car alarm sounds, you’ll know the key fob battery is likely the issue.
Solution: Replace the key fob battery with a new one, ensuring it’s the correct type for your Lexus model.
2. Weak Car Battery
A weak or dead car battery can also prevent your key fob from communicating with your car.
How to check: Try starting your car normally. If the engine is completely dead or you hear a clicking sound, your car battery might be the issue.
Solution: Jump-start your car battery or replace it if necessary.
3. Key Fob Programming Issues
Sometimes, the key fob might lose its programming, preventing it from communicating with your car. This can occur due to various reasons, like physical impact or electrical interference.
How to check: Try using the spare key fob if you have one. If the spare key fob works, the issue likely lies with the programming of the first key fob.
Solution: You might need to reprogram your key fob to your car. Consult your owner’s manual or contact a qualified locksmith or dealership for assistance.
4. Faulty Key Fob
Over time, the internal components of your key fob can wear out or get damaged, rendering it inoperable.
How to check: Inspect your key fob for any visible signs of damage, such as cracks, loose buttons, or water damage.
Solution: If you suspect a faulty key fob, you’ll likely need a replacement. You can obtain a new key fob from a dealership or a reputable automotive locksmith.

5. Issues with the Car’s Receiver
In some cases, the problem might not be with the key fob itself, but rather with your car’s keyless entry system receiver. This component receives signals from the key fob to lock, unlock, and start the engine.
How to check: If you’ve ruled out other possibilities and still can’t start your car with the key fob, there might be an issue with the receiver.
Solution: Diagnosing and repairing the receiver usually requires specialized equipment and expertise. It’s best to contact a qualified mechanic or dealership for assistance.
What to Do If Your Key Fob Still Doesn’t Work
If you’ve tried the above solutions and are still unable to start your car with the key fob, don’t panic. Here are some additional steps you can take:
- Consult your owner’s manual: Your car’s manual often contains troubleshooting tips and instructions specific to your Lexus RX 350 model.
- Contact a Lexus dealership: Dealerships have specialized tools and expertise to diagnose and resolve key fob issues.
- Seek assistance from a qualified automotive locksmith: Many locksmiths are equipped to handle car key programming and replacement services.
