So the other day my buddy got a g35 and my car was running but I took my key fob out the cubby it sits in to start the car to show him the key. After replacing the key the car started to act weird. All of the lights in the vehicle turned off from the dash to the cluster. I figured it was the key fob batter so went and got that replaced. Now the car won’t start at all. I took my battery To AutoZone they charged the battery and said it was a good battery put the battery back in the car still nothing no lights however when the car did start the engine was running but the lights in the car shut off. So call AAA they came out test the battery it is putting Out 13volts which is more than enough to start a car. Checked a lot of the fuses all of those seem to be good so I’m just really stumped it could be causing the issue. Please help me get my g back on the road.

 

Key fob got messed up maybe??
