My remote entry doesn't work anymore. I replaced the battery twice and still nothing. Is there a fuse or sensor that might be bad?

Have you reprogrammed the remote? See the owners manual. It's easy to do.

Drop in at your local Lincoln-Mercury service department and they will do a quick re-program of the fob. When the battery dies, so does the link to the car. :D

umm.. when i bought my ls one of the key fobs battery was dead. i just replaced the battery and it worked fine, and is still working now.
