Welcome to the club.
The above typed are all for throw away & Chineseium made parts & vehicle fluids.
Your local Junk/salvage yard for those "need it now bandaid last me for few weeks to save oem/factory" parts. Key remotes/key fobs, ECU/ECM, BCM, PCM, Multifuse, relays, engine, transmission fuel, exhaust.
Sensor, modules, remotes/key fobs & time consuming expensive parts always OEM/factory. OEM/factory engine oil filters (avoids problems & their cheap)
Pairing/syncing key remotes/key fobs to your vin/pin vehicle is a dealership only. Even the $5 to $8,000 snap on OBD2 automotive scanner will have trouble. Just buy dealership key remote/fobs & pay. Will save you hassles & money.
Owners manual can be purchased on Ebay, Amazon & your local dealership.
If you need specific info on your vehicle. The local Kia/Hyundai dealership parts dept can help. You can ask for info that paramount to make your DIY/repairs effective & efficiently.
I have several posts on my 1st gen Koup. Might give you some info/hints & or help.
Hope this helps
