So if your Elantra won't start, turn the key to where you can move the shift .... Having exact same problem on my 2011 elantradid you find out ...

im sorry to say but on this one you will have to go to a hyundai dealer and they will have to use there scan tool to reprogram the new key fob and also have the old keys with you because they will have to reprogram them as well. if you do not bring the old ones and they program the new one, the old fob will no longer work. this job will make you pay a half hour for a five minute job.
hope this helps

Hyundais have the tendancy to blow the ignition switch, yours was probabbly replaced, and by doing so you will need the Original key the car came with, not the new one included in the kit for the ignition switch.. also have you checked the little battery for the keyfob??? it probabbly went dry.

best regards!

Check engine block ground.
Check starter.

Check the starter relay.

The solution is to pull out the back seat to get into the trunk. There are two bolts holding the bottom part of back seat (bolts located between bottom and top sections). Then pull out bottom section of back seat and you see the hinge for the top section, remove the bolts and then you can lift up and access the trunk. It's not that hard.

It wouldn't be the car battery, but since you just purchased the car, the dealership should correct the problem. Bring it to their attention right away. Did you get any kind of warranty? Most dealers have at least a 30 day warranty for things like this.

The Radio is a True Statement. It will need a Lockout Code installed to bypass the Theft Deterent. On the Remote, The light will still flash But, It could still need a Battery anyway if the Battery has just enough Power to Turn the Light on and not Enough to send the Code to the Vehicle to Perform the Desired Actions.
