All power is lost when I get in the car to turn it on. I opened the door and all the lights come on, you know the dash and interior lights but it will not start.

300m and found that if you left the light switch on AUTO far left position it runs the battery down. which would mean your battery is most likely dead. if you have a volt meter try checking the battery directly from the posts and have some one try to start the car. if the reading goes under 9 volts you have a bad battery it happens some times even with new cars. if it stays at 12 volts you have a wiring issue. if the battery is not at 12 volts when you test it try charging it up.
