Hello, I need some help please.

Was getting on the freeway and error message came up stating something about anti-theft then powered down seconds after. No power to dashboard. Tried a new battery in key fob, tried my second key. Got the car home and scanned with OBD2 has a bunch of error codes with low voltage. Tested the battery and it only had 11.5 volts. I wouldn’t think that would make the car go haywire but I’m not sure. 2016 camaro 1ss

Tried a new battery and no change. Anybody have any idea what to check next.

Low voltage makes the control modules go haywire. Get a new battery

Agreed - that's the place to start. These cars do weird things when the battery charge is below 12.3V

16 is old enough to have a used up battery.

A shorted cell will wreak havoc on the computers and cause all sorts of false codes. Replace the battery.

Tried a new battery and no change, is there some kind of reset for the anti theft lockout?

I had a 2011 Silverado do this and after 5hrs or so at the dealer and a bunch of money it was one of the fuses for the anti theft or BCM I believe I dont remember, but id check all your fuses with that lockout thing

Specifically check BCM fuses, check all the fuse boxes
