I have a 2004 Grand Cherokee Laredo and the remote unlock fobs (both of them) work only within a foot or so of the car. Batteries in both have been changed but that did not solve the problem. I used to be able to unlock the doors from quite a distance.
Have 2004 laredo that the power locks/windows do not work from the inside and the dome lights stay on after the car is running and the locks do not lock automatically after it starts running? Now car will not start, will not turn over. When I turn key back to off position - the lights and dashboard go crazy. Any thoughts!

Only electrical work of any kind was having an after-market in-dash CD/satellite radio installed, but that was in 2005 and this key problem has only been going on for about 6 months.
That leaves you with the reciever having gone bad or the batteries weren't as good as you were led to believe. If you have a book, see if it lists where the electronics are located and if there is an external antenna for it.
Sounds like the problem is at the other end, the receiver that controls everthing on the fob. Have you done any electrical work on the vehicle? If you have a maintenance book (not the factory manual that comes with it) it should tell you where it is. Probably have to replace it.
