Help! The car was shut off when I got to store radio wouldn't shut off when I opened the door. Locked then unlocked car with key then all dash board lights, radio, interior light everything went nuts?

did you try to restart it ?..... and did it start up ok?? ....a weak battery will cause the on board computers to go crazy like that ....if it does start and run you may have to try disconnecting the neg terminal on the battery for 20 secs and see if that helps to reset everything...(battery) is in the trunk next to the spare also make sur the trunk stays open when you do ..no way to get in it once the battery is disconnected

Well you see the reason for us locking and unlocking with the key was because when we initially got to store shut off car the radio wouldn't shut off then the security light came on the dash board and car would not start it did absolutely nothing. A forum said to lock unlock with the key so we did then the car started and so we shut off to go in and that whole car lit up every light radio interior lights all went nuts we stuck key back in started it and decided we better just go back home. It has not done it in 2 days we worked on car today the check engine light was on and it was the oil pressure sensor so we replaced that today but it still has not gone all crazy like before

How do I get my radio to come back on the whole screen is blank when I cut on the push start the Dodge sign don't even Pop up
