so i was trying to reset my car so that the oil maintenance sign would go away after an oil change. Pressing the start button twice, while holding the other button. Then my car just wouldnt start, I jump started it and it slowly came on but the speedometers was completely shut off, and after i turned it off to restart my car it just wouldnt come on. I have no idea whats wrong.

 

Have you tried jumping it again? Sounds like your battery is bad. One of the symptoms of a weak battery is that the gauges don't sweep during the startup sequence.
