I had this problem. Through some research and asking some service personnel I found out it is a fairly easy fix. You will need to buy a new relay switch for the door locks. The dealer will/should know what you need. They are located (two of them, buy two and replace both) on the back side of the fuse box. It is not that easy to get back there. I had to lay on my back with my head up under the instrument panel. They are visible and can be removed if you take some time and be careful. Once I knew what I was looking at, it was easy to replace and the remote works like a charm. You can go to an auto supply, like Autozone, and they should have a schematic to show you where these relays are.

A tune up is generic. i don'y have specific part numbers or anything, but a tune-up generally consists of:
Spark Plug replacement (6 of them)
Spark Plug Wire replacement (6 of them)
Fuel filter replacement
Air filter replacement
On older vehicle, one would check all the components that involve spark, such as distributor cap & rotor. You might not have these, yours may be computerized, no service required until it fails.
A tune up would also include a review of all recommended service items as noted in your owners manual. Some of these might be mileage related. Such as, timing belt & transmission fluid replacement.
I normally do not do tune-up's unless the vehicle is having a problem. If you end up taking your vehicle to a mechanic to diagnose a problem, he will suggest many of these items before beginning his diagnosis.

"Fuel system too lean at idle". It's an air/fuel ratio that is not correct, possibly a vacuum leak somewhere. Or a leaky exhaust pipe. Could be related to intake manifold gasket. Somewhere, air is getting into the engine.
I suggest taking it back to the dealer under warranty. I think Hyundai is 10yr./100k for the original owner. 5yr./50k if not. Ask first if covered, and ask why not id not covered.
