Troubleshooting Common Key Fob Issues
Sometimes, replacing the battery isn’t enough. Here are a few common key fob issues and how to troubleshoot them:

- Key fob intermittently working: This could still indicate a faulty battery, even if it’s new. Try a different brand of CR2032 battery. If the problem persists, there might be an issue with the key fob’s internal circuitry.
- Key fob not detected by the car: Try holding the key fob closer to the start button when starting the car. If this doesn’t work, reprogramming the key fob might be necessary.
“A common mistake people make is not checking the orientation of the battery when replacing it,” says John Smith, Senior Automotive Technician at Smith Auto Repair. “Make sure the positive side is facing up.”
Another expert, Jane Doe, Lead Electrical Engineer at AutoTech Solutions, adds, “If you’re experiencing intermittent issues, don’t automatically assume it’s the key fob. There could be other underlying issues with the car’s electrical system.”
