Question about 2006 Hyundai Sonata
The remote will unlock doors and open trunk but will not lock the doors. I tried both remotes and had the same problem.
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.

I own a 2005 NF 3.3ltr Sonata Elite. The vehicle has only traveled 47,000 kilometers. The problem is the door locking mechanism seems to have an intermittent locking/unlocking fault or the computer is at fault.
Once the door locks are activated by remote or on the door consol, the rear passenger door will lock and stay locked for minutes, days or weeks, it cannot be opened externally or internal by any means. Also other door/doors will not lock at random.
Hyundai have replaced two actuators including the main unit in the driver’s door but the problem continues randomly on various doors.
Hyundai customer service in Australia (NSW) said it is not possible to repair faults that cannot be seen or tested by the dealership, so unless it happens and some else witnesses it from the dealership it wont be dealt with, plus it is apparently not consider a safety issue????
Is not a car door considered an escape hatch and therefore makes it a safety problem or the vehicle unroadworthy

I have exactly the same problem. Keyfob will unlock the doors, but will only arm the alarm once the doors have been locked manually. Central locking button on driver side door no longer works, but I hear the clicking sound you're referring to.
I took it to a mechanic, and he seemed pretty sure it was a bad master window / door lock switch. The price he quoted to replace it was $255 plus tax, and I could never bite the bullet and pay for the work, so I've just been living with the problem.
Have you solved your situation yet?
