one key fob doesn't work

[kmartin]

I have a 2004 Ford Explorer Sport Trac. The one key fob stopped working. The other still works. I tried replacing the battery. That didn't fix it. Any other idea? Or a total key fob replacement?

Look and work just like OE once programmed.

Can I just replace the bad one or do I need to do both?

you can just replace the bad one. refer to your owner's manual for how to program the new one. it's quite easy to do.
