Please dont worry yourself so much the security locks needs to be reprogrammed to enable it work effectively. Same happens to other vehicles as well.
Consult Hyundai garage close to you or if you have it in your manual.

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.

you have two relays on the interior fuse block one for locking and one for unlocking. Swap them and see if the problem is now such that they will not lock. If so you have your answer.

Same thing happened with mine. It turned out that the
power door lock motor went out. Since the handle or the switch can unlock the
driver's door, both of these mechanisms are connected. When the door lock motor
goes out it freezes in whatever position, it was last engaged.
