2. Reprogram the key fob: If you have recently purchased a spare key fob or replaced the battery in your existing key fob, you may need to reprogram it to work with your car. You can take the key to a Lexus dealer and have it reset for a fee, or you can try reprogramming it yourself. The process may vary depending on the model and year of your Lexus, so it’s best to consult the owner’s manual or contact a Lexus dealer for specific instructions.
3. Check for electrical problems: In some cases, a malfunctioning key fob could be due to electrical issues in the car. If you suspect this is the case, it may be necessary to have the car inspected by a professional to diagnose and fix any underlying electrical problems.
It’s worth noting that these are general troubleshooting steps, and the specific solution may vary depending on the model and year of your Lexus.
