Troubleshooting Common Key Fob Issues
Sometimes, key fobs malfunction. Here’s how to troubleshoot common issues:
- Key Fob Not Working: The most common culprit is a dead battery. Replacing the battery is a simple and inexpensive fix. See our guide on the 2016 toyota 4runner key fob battery type for similar battery types. If replacing the battery doesn’t work, the key fob itself might be faulty and require replacement.
- Key Fob Range Issues: If your key fob only works at very close range, the battery might be weak or there could be interference from other electronic devices.
“A weak battery is the most common cause of key fob issues. It’s always a good starting point for troubleshooting,” says John Smith, Senior Automotive Technician at Acme Auto Repair.
