Key fobs not working

I recently had two new key transmitters reprogrammed. They have stopped working as of yesterday. Took it to the dealer and they said it could be the Radio Frequency Module. Where is the module at and can I replace it myself. How much do they cost.

The switch in the passenger side front door, the one with the window switch in it, controls your lock/unlock feature throughout the whole vehicle. I was fortunate when my 2002 WJs keyfob stopped working to have a donor from a 2000 WJ. I put the door module from the 2000, which has always worked, in the 2002. Now I simply use the fob from the 2000 and everything works perfectly.

Before spending a lot, you may want to try and get a door module and fob from a junkyard WJ. Just make sure they come from the same WJ and you won't have to reprogram anything.
