Hi guys, new to the C7 corvette! I love my car but this morning I went to get in it and the driver door latch made the noise on unlocking then it locked back, now I can’t get in, i used the key fob and I can only see the car lights come on like it unlocking and alarm beeps when I lock, but doors won’t open and can’t hear the mechanism for the doors, is there a way to access the inside or thr car without braking the window ???

Where is the pull tab ???? It’s a convertible so I can’t get in the cabin
Welcome to our forum. Yes, your key FOB contains a physical key. Release the key from the FOB and go to the back of your C7 near the regular trunk release button. There you'll see a place to insert your mechanical key. Once you open the trunk, on the left side (driver side) there is a pull tab to manually open your door.

Once you get everything done, it sounds like you need to replace your battery. Here is a link on how to do that RedHot gets a battery for her upcoming 4th birthday

Did your alarm go off when you popped the trunk with the key? It should.

If not, then something is not right. Check the car battery connections.
It actually didn’t, and doors still not working either, car starts but it seems like an issue with the transmitter, remote is got new battery and it’s still says key fob not detected, even when I put the key in the slot! I’m gonna scan it tomorrow for codes, is this a common issue ?

Zmachman - first congrats on the car! Second, I have never heard of this issue and I have had 2 C7s. Once you get back into the seat and start her up, does the alarm stop beeping assuming it beeps when you opened the trunk.
I’m getting no alarm whatsoever, back up camera not working, air bag light on, tc light is on, doors still don’t open, I’m getting a code

Even with a new battery, if you are not driving your Stingray for sufficient distances on highways vs primarily short errand type runs, it may not be properly charged. Do you use a maintainer like a CTEK connected to the accessory outlet in the trunk (the one in the car does not allow for charging of the battery) when the car isn't driven for days on end?

C7s tend to be quirky when the battery charge is low and present all sorts of strange electrical issues.
I drive it almost every day, I got the battery tested and it’s 100%

Simply changing out the battery on a C7 will not normally cause any lingering issues with the anti-theft system that would require a trip to the dealer. This is true even when you change the battery and don't temporally use a small charge to 'maintain' systems while the battery is out. It is completely safe to change the battery with no auxiliary power source used until the new battery is installed (if done within a reasonable period of time). Normally all that will occur from the lack of power during the exchange, is that you might have to recalibrate your windows, the alarm/horn may sound on initial reconnect (but is easily reset by the FOB or starting the car), tire pressure sensors and external temperature sensors may read erratically until you take the car for a post installation ride.

I’m getting all these BCM codes, ordered one from the dealer $125 and I got a mobile electrician/programmer guy that’s gonna come program it for me for another $100 worst case I lose 200 bucks if not then it’s goin to the dealer!
One thing I noticed when I pulled the carpet to check the BCM is that the floor was wet, it seems like there is a leak in the door weather strip somewhere ?? I think moisture got into the module and fried it

I am gathering this was used C7 when you obtained it and you do not know its full history. Water under the driver seat could also be from a windshield leak in the past or worse.
Yes it’s a used vehicle that I just bought last month, windshield leak ? How do I stop it ? It’s not under the seat, it’s under the dash

So I got an update!!! I pulled the carpet to install the new BCM and get it programmed and there was water under the passenger side carpet, it looks like it’s been leaking rain water from the side of the dash board, I was reading some people complaining about water leak from the windshield ? Or by the firewall ? Any ideas ?

Windshield seal would be the first place to look, after that I would make sure your AC drain is not clogged. If it is, it can spill over into the footwell.
Just an update, vehicle is fixed, you were right from the beginning, water didn’t affect any electronics or cause any issues, one of the fuses on positive battery cable was lose, not sure how that happened but it’s fixed now!
