When I unlock my doors with the key fob and then try to get in the front driver or passenger side all the doors lock themselves. If I fiddle around a few times I can usually unlock the doors with my key.

Try replacing yoru battery first in key fob. Then try another key fob and see if it does the same. You might try disconnecting car battery for about a minute then reconnecting and see if that straighten s it out, if not you'll have to get it scanned to seee if anything is wrong with it.

I have three key fobs and it does the same thing with all of them. The key fobs have nothing to do with the doors locking themselves when I try to open the door. It also has nothing to do with the battery. The answer is something to do with a solenoid under the dash. I was trying to get a little more info about where under the dash.

I'm sending a pic of the transmitter inside the car it is in center of dash. It connects to the etacs unit which is in your junction block. Either of these could be bad or maybe reprogrammed.

Thank you for the picture and the help. Since I started having trouble with my front passenger door about 4 months ago and I just started having trouble with my drivers front door and the other 2 doors are not affected does it sound like this part could be the problem? I have asked people on the internet about this and evidently a lot of people have been having this problem and the only person that had any idea of the solution was something about a solenoid. Is this part called a solenoid by any chance?

No, it's actually a receiver the solenoids are in the doors. But the reciever connects to the etacs and one of them is givng the wrong signal, AFter looking at tsb's thereis a problem with kia receivers for losing thier memory, which kind of sounds like yours. You'll have to take to the dealer and have them test the key fobs for strength as well as see if yours will qualify for a new receiver. However I do not know if there will be a cost involved with this. But I thik kia gives a 100,000 mile warranty but I dont know if it's drive train or what.
