Why is My Hyundai Elantra Key Fob Not Working?
Before we jump into the replacement process, let’s troubleshoot some common reasons why your key fob might be giving you trouble:

- Signal Interference: Strong signals from other electronic devices can sometimes interfere with your key fob.
- Programming Issues: In rare cases, your key fob might need to be reprogrammed. This usually happens if the battery has been dead for an extended period.
