Hi, and sorry if this is the wrong part of the forum to post 'problems' about Tiburons, please move the thread if so. Well to get down to it, I ended up losing my Tiburons' real key that the car was purchased with, and stuck a never used imitation key in my ignition, but was still made from the Hyundai local dealer. It felt very like it had a lot of 'smooth' resistance when I stuck it and and turned it all the way to start the car. After many attemps of trying to get it out, I believe the cars' ECU recognized that it felt someone was trying to theive the car, so it has locked itself down, and not letting me charge the battery at all, ruling out being able to enter the key code that I could have tried to enter if the cars' battery was fine to let the ignition release the key, but no power, so nothing able to dial in. I have tried wiggling and reading everything I could on it, about turning the wheels and trying to wiggle the key out, shifting gears while, and letting the car roll in either direction then trying. It just seems to be a stubborn key that has not been worked and hung up because of its 1st time use, also some WD-40. This has now been going on for 4 days and holds me back from being able to take the Tibby anywhere, so help or words of any type will be much help, if I can be clearer let me know. Thank you

your car should still be under full bumper to bumper warranty which includes roadside assistance and towing . Have it towed to your dealer and let them fix it . My Tib had keyless entry with a anti-theft engine immobiliser , the keys were chipped and programmed to the bcm or body control module . You can't just cut a new key from a blank . Your keys should have come with a small coded metal plate , the dealer requires that number code to match a new chipped key to your bcm . I'm not sure why you can't remove the replacement key , the dealer may have to dissasemble the ignition switch .
