My car turns over and won't start have replaced lots of sensors but have finally found out it is a security problem. When I put key in the dash has a pic of a car with a key it flashes then goes out its suppose to stay on or the car won't start any ideas to help please. Be easy on me I'm a 60 year old woman lol

The car's security system may have a problem with the key. If you have a different key, try it. I would also remove and fully charge the battery, which most auto parts stores will do for free. A low battery may give the security system the appearance that somebody is trying to steal the car--be prepared to enter the radio code. If the problem persists, call your local Hyundai dealer--they may have a simple solution for you.
