Take your car to an AutoZone and ask them to pull your codes. They offer this for free, and it will reset your engine light, and you'll get to know why the light was on. Until you actually fix the problem though, the light will just come back on.

The check engine light, on your Hyundai Elantra can be reset by removing the fuse. Keep the fuse out for 10 seconds and replace it to its slot.
your question makes no sense. the imobilzer would be if you disconnected battery.it shouldn't matter if you replaced it with a 04 engine. unless you have a bad crank position sensor. or a bad ignition switch for security.
I own a 2001 tiburon and checked my owners manual. The light is the malfunction indicator light (MIL). It uses a sensor in the exhaust system to detect when there is a change in the composition of the exhaust gases. The MIL is pretty good at catching "little" things wrong with your engine so if your experiencing any change in engine power or in fuel economy I would recomend you have your tiburon checked out.
you disconnect the battery for a couple minutes.
