I know what you're thinking, you've seen this topic a dozen times, but this one has me a bit baffled. Here's the story:

I picked up my C6 in April and only one of the fobs works properly, as the other one just says options unavailable. So I don't bother using that one even though it's in perfect shape and the one that works looks like it's been through hell and back. But pretty much as soon as I got this car, the DIC would tell me "fob battery low" No big deal, I can get these batteries at the local dollar store in a pack of 3 for $1! So I change out the battery and all is fine until this week and then all of a sudden I start getting the fob not detected error. So even though the battery in the fob was still pretty fresh (and the packaging for those batteries shows they are good until 2015 so it's not like those batteries were very old stock) I changed it out this morning and it's working just fine now.

I'm just curious as to why I didn't get the fob battery low error this time around and instead it went straight to the fob not detected error? The last time around it never did give me a fob not detected error at all. Has anyone else run into this anomoly? Also, are these fobs really going to go through batteries this quickly? (which isn't that big a deal when I get them so cheap, but it's still rather annoying nonetheless)

 

My Fob battery just plain died the other day, no low battery error message in the DIC, just Fob not detected. My battery was pretty fresh as well (few month old).

I chaulked it up to "it happens". I swapped out the battery and now it's fine again.

 

What brand of battery? Three for a buck may be why your going through batteries so fast.

For me the Chevy Dealer in Sioux Falls actually swapped the battery for free because it was only a couple of months old and the guy at the counter noted it should last a minimum of 3 years. I believe it was an energizer they used.

 

They are Sunbeam batteries. I've used them before in other remotes and they've lasted a long time. Although a quick Google search showed me that they might not be all that great of a choice! If the one I put in there now ends up dying quickly I will definitely buy another brand next time around!

 

I was checking out your checklist last night Elmer, it's a great resource! I followed the steps and after changing the battery I am glad it solved the problem, but am still curious as to why the DIC didn't tell me the battery was low.

 

Which battery Pat?

 

The fob battery. When I first got the car the DIC told me the fob battery was low which is why I changed it in the first place, but yet during that time I never once got the fob not detected message. It seems odd that this time around I didn't get any message at all telling me that the fob battery was low, even though that clearly seems to be what the problem was.

 

Hm... I guess low as compared to no is the difference between the two messages. Your battery may have taken a quick dump rather than a slow ebb of power and thus the no instead of low.

It is likely that the reason that your second fob does not have options is that the original second fob was lost and the one you have was programmed as the #3 fob in the system. Only fobs 1 and 2 have options, 3 and 4 do not - even though all the fobs are identical electronically. If you want the second fob to have options, you can reprogram all the fobs using the long method in your manual - or get the dealer to do it.
