I have a 2011 JKU and my remote will not work. When the driver door is open it dings non stop like the keys are in the ignition or the lights were left on. I replaced my ignition switch today and as soon as I plug the new one in without even attaching it to the steering column it starts dinging again. The little rod that on the ignition that tells the switch weather the key is in it is not broken or gummed up. I was just about to give up and I pressed the button on my key and it worked (while the new ignition switch wasn’t even attached to the column but was plugged in). I reassembled and the beeping didn’t stop but the remote worked. Everything worked perfectly for over an hour until I cranked the jeep. After I cranked it the remote stopped working again and hasn’t worked since. Nothing appears to be damaged and it worked for awhile so I really don’t know what to do next.

I would start locating your grounds and cleaning them start with the battery terminals. Also insure that the battery is fully charged and your remote battery is new and good

The battery in the jeep is brand new and the remote battery is also good and sending strong frequencies. Do you know which ground specifically it would be?

Sounds like a ground isn't... grounding properly.
Changing the battery in the key might also be an idea to eliminate that as a problem.

Battery in the remote has been replaced recently and it’s sending out strong frequencies I believe the problem is with the jeep itself. Do you know what specific ground it might be?

Left of the pedals on the body side is a group of grounds

Is there supposed to be a ground wire on the stud in the very back closest to the firewall?

As far as grounds you are going to have to reference very specifically a 2011 diagram. You still have a 3.8 but have the updated interior. You have the only year with this configuration. Just FYI

You'd have to look at the ends of any of the wires that are hanging around to see if they have a ring terminal on them.

Here’s what I found, the wire that is dangling is red and tan and does not have a ring terminal. No idea where it came from. It is not stripped on the end so I don’t think it was pulled out of something, it looks like a clean cut. Never even noticed it until I started chasing down this issue.

Edit, I stripped the end and touched it to the existing ground with no change. I’m not sure what’s going on here

I would put a meter on it and see if it is a power or ground or it could be a nothing that a PO added at some point
 
Hmm... I wonder if the previous owner did something with the door sensor. Or something happened in general.

So the key fob doesn't work at all? The alarm doesn't either? Or the driver door won't lock / unlock? If you press the lock / unlock buttons twice fast do the other doors lock?

It could be the WCM, Wireless Control Module as another thing to look into if neither key does anything.

A bit of an update, if I unplug the connector to the WCM and plug it back up the key fob works and functions perfectly. Then, I’ll crank the jeep and shut it back off and it won’t work again. Do I need to replace my WCM?
