Troubleshooting: 2003 Nissan Altima Key Fob Not Programming
Sometimes, the programming process might not go as smoothly as planned. Here are some common issues and how to address them:
- Incorrect Timing: Ensure you’re cycling the ignition key precisely six times within ten seconds. Too slow or too fast, and the system won’t enter programming mode.
- Dead Key Fob Battery: A weak or dead battery can prevent the key fob from being recognized. Try replacing the battery before attempting to program again.
