When trying to start my car, it does not start, makes a clicking noise, and all the electronics are going haywire. Headlights, dash, interior lights rapidly flashing, sometimes it says the key isn't detected, sometimes it says refuel. When trying to unlock/lock the car, the mirrors aren't folding out and the lights rapidly flash.
Here's a video of a little of what's going on: Streamable Video
I checked the voltage on the battery and got around 12.53-57 so I don't think it's a voltage issue. Connections are clean and secure on the battery leads. The car was driven with no problems roughly 4 hours ago, so it is not an issue with it sitting for a long time.
Any idea what this could be?
