After fiddling with 2 new keyless entry devices for my 04 Jeep Grand Cherokee, I came to realize the problem may be within the car itself.

In short I need to be standing next to the drivers door for it to work. Move 10 feet away and nothing. I tested the strength of the transponder key itself at one of those test devices at Autozone and it got a good 40-50 feet.

So this begs the question.. where is the receiver within the Jeep and can it be repaired/replaced? I am hoping this is something simple perhaps like a bad antenna on the receiver, but I dont even know where to look for thie device in the car. Google this and there are many opinions about the location of the receiver. I do have the overhead temp display & a sunroof if it matters.

Help is appreciated!

Not familiar with Jeep system, but GM had the same problem and it's a quick $10 fix. I can now open my door from across the parking lot.....
Don't have the web site available now, am away from home... It is a factory system or after market??

The keyless entry receiver and antenna are in the passenger door and are part of an integrated module that also works the locks and windows for the passenger side. You can easily open up the door and find it. In some cases the antenna will be kinked or damaged and there's your problem. Anyone with a decent amount of electronics repair experience could replace the antenna as it's a simple piece of wire. If the module itself is faulty, you not only need to replace it, but also have it programmed by the dealer. All in, you're probably looking at around $400 or so to have the module replaced and programmed.

I recently bought a 2004 grand cherokee limited, everything was fine till about 3 days ago. Then the keyless entry stopped working on everything but the drivers door, (which also happens to be the only keyhole on the thing) So of course, this being my first jeep, (not to mention my first keyless remote) I thought it may be something to do with the key fob. But apparently it's something else, as none of the inside electrical door lock controls (with the exception of the drivers door controls, which only works for the drivers door) seem to be working.
I thought it may be a fuse or a programing issue, but although I have read the owner's manual several times, I am at this point drawing a blank. The only thing of use I got from the manual is that there is a emergency liftgate release, (Somewhere, And it doesn't state where) which can be accessed through a snap-in cover located on the liftgate trim panel??. No details whatsoever. Doesn't state if it's inside (which would make sense) or outside, which makes no sense at all. Any ideas or help that I receive at this point would be greatly appreciated. I'm afraid that this is gonna wind up being a dealership resolved problem and I'm dreading that. Thanks.

I am experiencing the same problem with the same vehicle. Regarding the emergency open the hatch method described in the manual, I agree with your opinion about its wording. I have determined that it is on the inside trim. I found it before the need for it and did not know why the opening is there. I have not actually used it yet. My keyless remote will function about once every two or three days, and it opened the hatch and I have not been locked out of it again yet.
I am working with the used car people I bought it from now for them to find the problem. How did you (if you have) solve the problem? I will post here with results of my solution when it has occurred.

Default followup to keyless entry problem 2004 JGC

My problem resolved itself around the first of May, but has recurred as of about June 25th. I get no response at all now. The driver door is the only one that works at all, and that is by operating the rocker switch (after unlocking it with the key). It is supposed to unlock the hatch as well, but does not. I regret buying this jeep as it will become way too expensive to pay for dealer repairs.
