Why won't my key FOB work?

2011 Ford F-150, I went to use my key fob and it didn't work at all, so I went to use the key in the door and that didn't work either. Luckily the keypad worked and I got in. I reset the fob without getting a new battery and it works now, but still my key won't work in the door, and also I was wondering why did I have to reset the fob? What could've gone wrong because I didn't even have to change the battery…

I'm glad to learn that your concern has been resolved!

I definitely recommend contacting your local Ford Dealer. Ask to speak to the service manager. He'll be in the best position to answer the inquiry about your key fob.

Have a great day!

The battery might be weak or got wet and corroded.
