I have had the fob fall out of my pocket when the pant pocket is shallow.

 

Not that time. Believe it or not, I did it again last week. This time the horn did been and I was able to open the door. I guess it depends where exactly the key fob is in the trunk.

 

I take mine out before putting the pants in the washer.

I agree, too bulky. When I bought my C6 I took the key from the second fob and placed it under the car in a Hillman Hide-A-Key magnetic box. OTOH I couldn't find a good place to attach it on my C7 since it has far less ferrous metal for the Hide-A-Key to mount, so I bought the instead, which attaches with Velcro.

I used it on my first C7 one day when I was fueling after a session at the gym. I had my phone, wallet, and fob in my workout bag and exited the car, which subsequently locked me out. I thought the phone might have been interfering with the fob so after using the spare key to re-enter the car I placed the fob on top the console, closed the door, and it locked me out again. Had I not had the spare key outside the car I would've been up the creek. When I returned home I checked the voltage on the fob battery and it was 3.05V, so I replaced it with a new one which showed 3.3V. Did not have a problem with it again, although I traded the car soon thereafter (not for that reason). It was ~20 mo. old at that time.

Had I kept a spare key in my wallet like I did in all cars prior to the C6 I would've still been up the creek in this particular case, so the exterior storage was a good idea, for me anyway.

 

Ok. Came home from the gym. Tossed the fob on the trunk and shut it. No beeps. I swear it has done so before.....🙃

 

The trunk was a dead zone in my C6, so when I got the C7 I did some tests, throwing the fob in various places to find any potential dead zones. Didn't find any, but being paranoid I still did the Hide-A-Key option (see post #23 above). Glad I did. It's possible the battery in your fob was getting weak like mine was and the trunk was too far from the receiver to get a good signal.

 

I had one cut https://www.ebay.com/itm/GM-B119-2010-2017-8-or-10-Cut-Transponder-Chip-Key/123520639635?fits=Model%3ACamaro&hash=it em1cc2676293:gB8AAOSw-HRcAkKt

 

Just remember the key is how you tell fob 1 from fob 2...........

 

I think you have to be subscribed to OnStar for this feature to work.

 

Not really.

The numbers in the key base don't apparently correspond to anything. A few years back it was determined that many had two #1s, or two #2s, and even those who had one of each, the keys may or may not match up to driver #. Mine didn't match up ( no reason to think the keys weren't swapped for some reason between the fobs prior to delivery).

Not like the C6 where the number was on the fob itself, and they were always programmed in the order of the number on the fob.

 

Me too - I didn't have to ask for it, the spare was just given to me during the transaction. Outside of a hand-me-down Dodge Aries many years ago, every car that I've bought or leased I received two keys.

 

Would not fit period in my wallet! Since I carry in my back pocket would make a mess of the Vette seat and my derrière!

Now would work for the wife’s, as her wallet is so thick she must bring a handbag to carry it! But would not help her as she has never driven any of my 5 Vettes!

 

When I got my September 2013 built C7 that was a controversy on the Forum for months! Until someone figured it was the number of a two cavity forging die!

The worse folks to convince were the ones who’s number matched the FOB. The FOB number 1 is actually determined by the first one programmed as 1 (probably by the dealer.)

It’s purely probability! 50% had a 1 and 50% had a 2. Of the 50% that had a one, randomly half those would be correct! That is 25% would have a 1 and that FOB was the first to be programmed. They were a PIA to convince it was random and the key number meant nothing!

As you note, it’s in the replaceable key in the FOB. If you want them to match and they don’t - swap keys!

I use a simple approach visible without removing the key! A silicone cover!

 

That's what I thought. I pulled the key out of the fob, and in one of the indentations a very tiny "1" is stamped. Compared the second fob key and found a very tiny "1" stamped in the same indentation. My understanding is that the fobs on the C7 are identified by the order they were programmed into the vehicle. There are no identifying marks on the fob or the key in the fob to distinguish which is which. You are correct that the C6 fobs have the number stamped on them, in fact they are two different GM part numbers for a fob with a 1 vs. a fob with a 2. C7 seems to have done away with all that.

 

Agreed... I dont see a reason that fob comes out of the pocket besides valet and service.

Looking for solution to a non existing issue. And of course should have a complete spare fob at home.

 

As someone else mentioned, on more than one occasion I have had the keys slip from my pocket and fall under the seat. I'm OCD so whenever I get out of the car I pat my pocket to make sure my keys are there so it wasn't a big deal. I can certainly understand why someone would want a spare key.

 

Yup, although mine is blue!

And an added bonus is the cover makes it MUCH harder to "butt dial" your FOB while it's in your pocket

 

I never said it DETERMINED which was 1 or 2. It is simply a way of telling them apart w/o using a felt pen.

 

If you want to bother to remove the keys versus a colored cover, and yours are not correct- just reverse the keys and they will be! Would be a foolish thing for GM to use as a removable key as a FOB identifier!

Back in 2013 we had lots of GM customer service folks monitoring the Forum, as members. I asked one what the key numbers meant?

One responded with "our resources say" whatever it is, it's not something GM requires!

SIDEBAR
In fairness could not expect those GM folks on the Forum to know all answers BUT they had access to technical resources we do not.

However tried that with the statement in the front intro section of the 2014 Owner's Manual that said "You could jump start from the front of the car or the Battery." But that gave a page # in the back with information only about jump starting from the battery.

I asked The GM person BUT the wrong question: "Is the front of the Owner's Manual correct?" The answer came back and said a simple, "YES." Should have know they could not say the Owner's Manual was wrong from my experience with a large corporate bureaucracy when I had to get 5 attorneys to approve a monthly newsletter for distributors!

So then I asked, "Where in the engine compartment do you put the cables?" No answer. They were individuals with names just like any Forum Member so I sent several PM's! Finally the answer came back, "I can not get that answer from my sources!


That "location to jump start from the engine compartment error" was corrected in subsequent Owner's Manuals! There is none!
