Could be as simple as a blown fuse for the ETACS module, but it sounds more like a problem with the anti theft immobilizer system. Does your car have remote keyless entry? And is the key you are using a factory key or one someone made? (factory key will be encased in bulky black plastic with hyundai logo) The transponder in the key might have worn out and is not talking to the car anymore. Some hyundais use the radio antenna to receive the signal, is there an antenna on the car? Is it hooked up? If it is a problem with the key and immobilizer system, It will unfortunately need towed to a dealer and reprogrammed.
