When they say RKE module, I assume they are talking about the key-less entry control module. RKE stands for remote key-less entry so I am sure this is what they are referring to. However, if you get a part number of the part they are talking about, we can be sure we have the same part.

Here are the instructions of the key-less entry module. You need to program it so I attached that info as well.

Sure. I attached all the components for this. There are a number of different components so they may not be in order but each of these components need to come out. Let me know if you have other questions. Thanks

I have a sinking suspicion that the previous owners removed the RKE module from the car.

With all of the things the module does that isn't likely. Where did you get the new fobs from? I've had issues with some of the ones bought online not working because they had the wrong internal parts. Do you have fobs that do work?

Well, I didn't want to completely disassemble my dash just yet. I'm going to see if it's covered under warranty first.

Well, replacing the module isn't covered. Any ideas of what this will cost to have a dealership fix?

Couple of questions, do you have fobs that work with the car now? You bought the new fobs to add them on or did you not have any fobs and wanted them?

Steve, I do not have any fobs that work with the car right now. My key will unlock the drivers door, and I can turn over the engine, but the fob buttons do not work. I just found a document about the ignition door being stuck open, and stopping all fob functionality. I'm currently trying to remove the lock cylinder so I can grease the door spring. I have the top and bottom cover off the of the steering column now. But, I can't seem to get the cylinder out. Any tips on that?

Just found a video that shows I need a special key tool to get my ignition cylinder out. My luck is really bad right now.

If that is the item I'm thinking it is that applies to a bad switch in the drivers door latch, not the ignition switch. It tells the RKE module that the drivers door is open so the fobs don't work. The easiest way to test if that is the issue is to use a dealer level scan tool and watch the switch change from open to closed as you open and close the door.
Does everything else work except the fobs? Starts and runs good and all else seems to work, just not the fobs? No theft light on or constant door ajar indication?
PEPS battery fuse in the box under the hood is not blown?
The buttons that don't work control lock and unlock and panic correct? There are two versions of your car, one uses a keyed ignition and the other has passive entry and start where there is just a push button to start the engine. You have the key version?
If so it likely isn't in the switch you are trying to access.

Door chimes when you open the door, and key out of ignition.
I bought the fobs directly from the dealership.
"Theft Attempted" displays on the DIC after you start the car.
No door ajar indication, no theft indication (lock on car).
When I took it to the dealership, twice, they didn't see any faults.
Car runs and drives just like it should.
PEPS fuse not blown.
As far as numbers on the keys, I have:
Key 1 has:
GM13586120
CMII ID: 2011DJ0798
13210 #

Key 2 has:
GM13586120
CMII ID: 2011DJ0798
13170 #

Okay, the theft attempted indicator is the issue. That will shut off the fob's as the car assumes someone was trying to steal it. The only way to find out would be to scan the system and look at what the security system shows for the reason for the light. It sounds like a hard failure in the anti-theft system as that can turn on the light but the car will still run if you have a good key. That could be any of three modules and the only way to know is to use a scanner and the various tests as you monitor what is or isn't working. Not really a DIY project though unless you have a dealer level scan tool.

I've identified the issue. I was exploring the ignition cylinder as the probable cause. I have the high security ignition that requires a special tool to release the cylinder. I had a small pick that I put into the hole to see if I could some how release the cylinder. I was not successful, however, I was able to get the ignition into a certain position that made the chime stop, and I was able to use the key fob without issue.

However, when I put the key back into the ignition to start the car, the chime returned and the fobs stopped working again, and "Theft Attempted" reappeared.

It's safe to say that my ignition cylinder either needs to be replaced, or my entire ignition module needs to be replaced.

Okay, you are saying that the key in chime is staying on with the key in and the door closed? Or am I reading that wrong? If that is the case then it could be in the housing for the cylinder and it not reading the key properly.

So, the chime happens when the door is opened and the key is not in the ignition.

Key out, door open: Chime.

Key in, door open: Chime.

Key in, door closed: No chime.

Key out, door closed: No chime.

I was able to position the ignition cylinder with the pick that stopped the chime entirely and the key fobs worked without issue.

After I put the key into the ignition and start the car, the car runs turns over and runs without issue. When I remove the key from the ignition, the chime returns and the key fobs stop working.

Should I replace the entire ignition switch housing? Or just the ignition cylinder?
