I have a 2013 Grand Sport with 5200 miles. The key fob batteries died and I replaced both of them. But as soon as I did this I lost all power to the whole car.
I have tried placing the fob in the glove box to start but nothing. Can anyone help. I really don't want to have it towed to chevy dealer (yet)

Is it possible you installed the batteries backwards?

How did you determine the fob batteries were bad?

If the car was failing to start before, and now the accessories won't even power on, the #1 most likely cause of both problems is a bad (car) battery.

If the Fobs were unlocking and locking the doors the Fob was fine. When the battery runs low in the FOB you will know that the distance between the car and the Fob will less.

If the accessories are coming on, check the battery volts on your DIC read out and see if it is at least 11-12 volts. If it is lower than 11 it may be the battery. If the voltage is at least 11 volts than it could be the Safety Switch on the Clutch Pedal and if it is an automatic than the brake switch, has gone bad.

If you have a manual tranny make sure that the Clutch is all the way to the floor. On my 13 Grand Sport I noticed that there is not much of a threshold when the clutch is depressed in order to start the car.

If that is not the problem, looks like you may be having to have your car towed to Abel is in your future.
