Having electrical issue that myself, my mechanic, nor Hyundai can detect.

What Doesn't Work:
- Locking door from outside driver and passenger handle
- Unlocking door from outside driver and passenger handle
- Locking and unlocking door with keyfob
- Opening the trunk with the smartkey fob
- Opening the trunk with the interior trunk button next to steering wheel
- Opening the trunk by pushing on the physical touch pad

What Works:
- Locking door from inside drivers door
- Unlocking door from inside drivers door
- Locking and unlocking door via scanner plugged into OBD2 port
- Putting car in reverse will lock doors.
- Putting car in park will unlock doors.
- Opening the trunk with the physical key inserted

I am curious if someone has suggestions on what all I can do.

I went to a company that programs keys, they looked into it for about 30 minutes and said reprogramming the keys wasn't the solution and that it's something electrical.

I am going to try replacing the smart antenna and see if that helps. I replaced the trunk control module and that did not change anything.
