Keyless/Passive Entry Broke?
I have a windows valet and have it set to beep 3 times if someone tries to enter the vehicle without a FOB. The kids have already tested it. THe last few days I have been getting the 3 beeps while possessing the FOB in my pocket and the door doesn't unlock. I have to pull the FOB out and hit the unlock button and then I can enter the car. SO, I used deduction. I removed the window valet but I still can't enter the car without hitting the unlock button on the FOB. Next I replaced the batteries even though I have only used it for 6 months and it still unlocks the car from about 60 feet. I still can't unlock the driver door with the FOB in my pocket. When I pull on the door handle, I can hear the electronics doing their thing but no unlocky. Here is the kicker. With the FOB still in my pocket and failure on the driver's door, I can walk to the passenger side and it opens no problem. I did some searches but none reveal this issue. Any ideas? Oh, and I went through the options in the DIC and nothing has changed.

It sounds like you may have a defective Exterior Door Handle Switch.
You can test it by replacing it with the switch from the passenger door - very easy to remove.
If it works properly, you simply replace both switches.
Gene Culley sells them for $9/ea.
(I recommend replacing both, since you probably will have the same problem with the good one! )
Hope this helps!

Thanks FACADE, I will give that a shot when I get home and report back. Yep, I would rather pay the $9 than let the dealer touch it. I do hope that is what the problem is.

FACADE, I made the switch as recommended to no avail so we have further deduced it is NOT the pressure pads in the door handle. It was worth the effort just to get the dirt and grime removed with the handle removed. That was dealer lot time as that did happen on my ownership time. I think when I get home from work I will try disconnecting the battery as that seems to cure C6 ailments. One more note, when I do open the passenger side and then go to the drivers side, it will open no problems. Lastly, when I do attempt to open the drivers side with the FOB in pocket, as I mentioned, I can hear electronics working and the red door security light goes solid. Anyone else have a clue. Regardless, I will not rush to the dealer until I have to. Most of the time I use the key fob anyway to lower the windows before I get to the car. Thanks.

If the door will open from the inside button, and open with the outside button after you manually unlock it with the fob button, there's nothing wrong with the door switch, latch, or module. Only the passive fob detect feature isn't working, and that's only not working on the driver's side. That can only mean the B pillar antenna on the driver's side is faulty.
You need to understand how the system works. The car generates a very low power low frequency interrogation signal with a range of only a couple of feet when the outer door switch is operated. The fob in your pocket is supposed to detect this and respond at a UHF frequency (the same UHF frequency used when you press the manual unlock button on the fob, and we know that works). So the car isn't producing the low frequency signal only on the driver's side (we know it is on the passenger side because that still works). The only way this can be side specific is if the antenna on that side is faulty. QED

For the others that asked, yes, I did try the second FOB but I think Shopdog has explained why that is not a factor.
Shopdog, your logic makes sense. While I do have the shop manuals, can you steer me in the direciton I am looking for. I have removed the B-pillars before when I installed the HUD. Or is the B-piller something different. This just stopped working a few days ago, months after the install. I can't think where something could have gotten pinched or cut. Can you tell me where I might start looking? I really hope the battery thing works but I fear Shopdog is correct. Thanks all.

Someone who has done a faux Z06 conversion may have pictures of the car wtih the quarter panel removed so you can see the antenna wire. But before you start ripping quarter panels off the car, you might want to check to see if the wire has come unplugged from the RCDLR.

I tried disconnecting the battery for a few but that didn't fix it. I found the antenna removal in the manual. It will only take a few minutes. I have a Vert. I got find where the RCDLR is. The pictures are horrible in the manuals
. Thanks for all the help.

Another question. With the vehicle locked, I put the FOB on the drivers side and I was able to open the passenger side door. So, can the passenger side antenna act on behalf of the drivers side. If it can, this means that there must be something wrong with the receiver vs the drivers side antenna. Or is it that the passenger antenna can only act to open the passenger door and the driver antenna can only act to open the driver's side. I would think that if any of the 4 antenna were interogated, it would allow entry into either door.
If I buy a new receiver, does it have to be programmed before installation.....aka, might as well take it to the dealer for repair. Yes, at some point I am still going to check for loose wiring or plugs as shopdog has suggested.

Welp, I just removed the B-pillar. Carpet and pretty much the left side of the car and I can not locate the antenna module that the manual refers to. I don't see anything that remotely resembles the pictures in the manual. Guess this is a job for the pro's. I even had the wife looking. Her comment, "I think the artist was stoned." So, if anyone out there can be specific as to where the left side antenna module lies, please let me know. Thanks. I have a Vert by the way and yes, that is the picture in the manual I referred to.

I have good news and bad news. 2000C-5 was on the money about going through the gas cap filler.

Knowing that could save a person a lot of time. The manual is wrong, wrong, wrong. So, the good news is, I was able to swap the trunk antenna with the drivers side.
The bad news is it did not fix the problem.
So it is either a loose plug at the receiver or the receiver is bad. Darn it. I will wait until something else major breaks or I come up on warranty and have it fixed. I would bet I can't make an appointment and watch them fix the car?

What ever became of this problem. My trunk pad has rarely worked. And now the drivers door is spotty opening from the outside.
I'm leaning towards new pads since everything opens from the inside & with the fob buttons.

. Passenger side and trunk are still working flawlessly without having to manually press the key FOB.
