All four of my doors will not unlock or lock. What could be the problem?

What is your question?

When I push the buttons on my key they do not work. I changed the battery. When move the button inside on the switch, nothing happens.

What makes this problem better or worse?

It use to make the locking or unlocking sound and not unlock or lock but now that has stopped.

How long has your 2007 Dodge Ram 1500 had this problem?

Its been awhile couple years. I've been manually unlocking with the key and pulling or pushing the locks up and down.
