Had a neighbor looking at my car last night. When he got to the doors and figured out how to open them he said, "how do you get in the car if it has a dead battery"

I have no idea :confused:

Your fob has a key that will open the hatch. The key hole is by the back up cam.

Yeah, my manual is... inside the car in the glove compartment. Anyway, took about 10 minutes to figure out to take the key apart and find a place to put it. I use the car as a daily driver and had driven it 12 hours before. Now... completely dead, not even any juice to charge my iPhone. Gotta tow it to the dealer.

I've had it 8 months and drove it right through the winter (no problems at all on Michelin X-Ice's... well other than the cost) and had no problems with all the -30 and -40 nights. I'm at 16,000km and it was a beautiful above freezing night when it went dead.

Recently got a 2015 stingray coupe (multiprocessor on wheels) and was thinking about changing the stock battery to an Optima Yellow Top (lower CCA than Red Top, but deeper cycle). Someone told me to be very careful, as disconnecting the battery triggers the anti-theft system, locks up the car and it has to be towed into the dealer. Does anyone know if that is true and, if so, what is a workaround?

Key in the FOB to open the hatch... there is a pull lever in hatch area to open driver side door.

not true, I disconnect my battery every time I put it in storage ( every couple of months) I have had no issues.

Your asking for trouble as every time the battery is yanked at the least when voltage is returned you force every controller in the car to reboot, sync up in networks and for the PCM force it to spend computer clock time doing all the onboard smog tests that get erased and to a failed state when battery is removed from system

Long term as controllers get older
sooner or later things stored in memory flake out or a controller never connects to network fast enough causing NO comm DTCs.,

Smog tests alone depending on drive style can take days to get back into a passed/complete state so I suggest not removing battery but use a 1-2 amp battery tender as they work.
My 1999 C5 only has 31,000 miles on it so it lives on a tender ( including in 20 deg and below winter temps) and only the 2nd battery it has had still works fine.

I don't need smog tests, and it's under warranty. Since the dealership put (in writing) what to do for storage in a storage unit without provisions of an electrical outlet.

Has nothing to do with IF the car goes to a smog shop
it is the fact the PCM does not care or know that,
it does though have to do several drive cycles and keep doing all the built in smog tests until they get into a complete state
which takes away computer time to do all it's other functions.

Dealer knows zip if he says to just yank battery cable off.

cover all your bases on a prescribed obd2 test drive to get all the c.a.n. ecu's into a complete state, takes about 20 minutes. it's not that big of an issue. you just shouldn't pull the cables when ignition is on, or any of the other systems are on. I believe it would be worse to low-volt the system by leaving the battery hooked up and drained slowly. And especially bad if jump started.

I got locked out of my trunk today, and I had to use the same sequence as dead-battery vehicle entry.

First, access the mechanical key, insert it in the tumbler and turn to pop the trunk lid/hatch. On the drivers side of the trunk area, you'll find a black handled cable that opens the drivers side door. This cable may trigger the alarm, depending on the state of the battery and presence of fobs.

Having to manually access the trunk made me realize how much it would suck to have a dead battery, so I went to Harbor Freight and bought a set of battery cables ($12, or $10 if the cute cashier gives you a "20% off any purchase" coupon) in case that day ever comes. Given how much people love the C7, getting someone to give you a jump start won't be a problem.:)

Good show Mobius! You'd be surprised what kind of info is in the owner's manual, pretty much everything you need to know, all you gotta do is read it. :)

Yep, just don't have the owner's manual in the glove box when you're on the road and the battery decides to go "belly-up"*. ;)

Could not agree more. My battery died in a parking garage, after I had tried to lock the car with my phone. I think it kept trying, and just killed the battery. I keep a set of jumper cables in the same compartment now!

Currently my C7 is at the dealership for a yet undiagnosed electrical problem that drains the battery. My salesman told me he never travels without a an "Antigravity Battery" portable charger. You charge it once and it is supposed to jump a car battery for several months. It also works on cell phones and other electronic gear. I bought mine on Amazon for about $100. It fits perfectly in the rear storage compartment. Unfortunately it did not arrive in time to try it on my latest dead battery.

Bummer. Mine went dead once but I know what did it, my stupidity.
