Chevy Cobalt LT 07 Wont Start After Changing Key Fob Battery

So yesterday i changed the battery on the alarm remote for my 07 chevy cobalt and now it wont turn on. Im sure it must have something to do with it because i tried taking the battery of the remote out and the car started. Then i put the battwry back in and it stopped turning on again. Now no matter what it wont turn on. It doesnt crank. No noises coming from engine when trying to turn it on. Please help i have a newborn baby and need the car asap

Thank you in advance

Do you mean the car won't start with the remote start or the car just won't start with the key?

It doesnt have remote start i mean the remote for the alarm (unlock/lock) i try turning the car on with the key like usual. Note the remote does unlock and lock and activates alarm on car

Correct me if im wrong but is this for automatics? Cause im pretty sure my manual has no alarm system.

The FOB itself has no way of stopping the car from starting with the key. Coincidences happen. I would make sure the car battery is good. This time of the year with cooler temperatures batteries fail.

Isn't yours an XFE? Those things had basically no options to keep them as light as possible to maximize fuel economy.

Mine is automatic and came with an alarm system. And i had thr battery checked yesterday and they said its a good battery. Its just too much of a coincidence that as soon as i put the battery in the remote the car wouldnt start then immediately after taking the battery out it started perfectly fine. Then again after putting the battery back in the car it wont start. Now no matter if i put the old battery (which shouldnt matter if its old or new) it wont start at all.

I'm telling you there is no way your FOB can stop your car from starting with the key.

Ok so what other possibilities am i looking at here if it is just a coincidence? The car never showed any signs of something messing up. No noices in engine or anything out of the ordinary. When trying to start the car It just clicks once. (Seems like its from the starter) but does nothing afterwards.

Bad ground at starter or engine, boost post loose, loose connection at battery, it could be a lot of things but not your FOBs.
