Hello, these Hyundai's can be difficult with service information. So, this has a Push button ignition with a smart key you just need to have inside the vehicle with you, correct? I just want to make sure I'm following these Power diagrams.

Can you first check that the Stop LP Fuse 15Amp and the IG Fuse 30amp in the engine compartment fuse panel have power. They should have battery voltage all the time. These diagrams jump back and forth through 6 pages, so let's see if we have power starting there.
The power for those 2 fuses comes from a long Multi Fuse which is a long Fuse bar looking thing, don't try to pull it out, just first verify power on those 2 fuses first.
Also be careful about swapping relays around, this is not recommended anymore due to the unique system relays used now, most relays are now designed for use in only one location and should not be swapped with other relays even if they look the same.

If you do have power on those 2 fuses, next check the PDM 2 Fuse 7.5amp which is located in the I/P Junction Box on the driver side dash.
Through many locations this fuse gets power from the Multi Fuse bar in the Engine compartment fuse panel. Checking this PDM 2 fuse is important because it's not possible to get these Multi Fuse bars open to check them and a visual check is very difficult most of the time. So, if power is missing from that fuse, that would explain why the Start Button is missing power. I'll post some diagrams showing how these fuses are linked together.

Was it this fuse? ROOM LP 10amp? We might have to go through some of the components on that circuit if it happens again. It takes a short to ground to blow a 10amp fuse. If it does happen again, take a look at the components on that fuse, and see if you can remember what you did before the fuse pops. For example open the trunk or something along those lines, there is a lamp for the trunk on that fuse.
