when i get in the car it says changer parked and when itry to start it it only

all the lights work everthings bright its not the battery thats one of the 1st things made sure of.

How old is the battery?.. Keep in mind it takes a hell of a lot more power to crank the engine than burn the lights!.. Turn lights on and attempt to crank engine.. How bright are they then?

they stay the same just turn on and off and the locks pop up an down and the cd player goes crazy

How old is the battery? I'm trying to help you out here...but I need more info!

2 years old even took back to o reilys and the said it was fine

At this point it's beyond Internet repair.. Suggest having car savvy person have a look at it and do some hands-on testing.
