Driver's door can't be opened. This 2005 Kia Optima EX has power door locks. I can't open the driver's side door. The passenger door works fine. I hear the motor when I try to unlo


Pull the door panel and find the cause, it can be a faulty lock motor or the linkage rod has come off due to a broken retainer clip.

I can't unlock my 2003 kia rio with the key, and when I unlock it from the inside it relocks itself before I can open the door


Hello,
Just had the same problem and know it is fixed.
You may have worked out that you can use the fob to unlock and then immediately lift the passenger handle to get access- not ideal.
In my case I couldn't turn the key in the drivers door either
1, Remove the 25 AMP fuse for door locking from fuse box under the bonnet. This disables central locking. The passenger door opens fine. The key however won't turn in drivers door.
2, Spray WD40 or other moisture repellent protective lubricant on key. Insert into drivers lock- gently turn back and forth. Half remove key so you can spray more WD40 into lock- a good blast will do. Keep gently turning until you can lock and unlock.
3, Replace 25 amp fuse
4, Hopefully job done- worked for me

Am about to buy a used car KIA Optima V6 2003 with 65000 miles on it. What are the common problems with this kind of car? I never had one before though it looks pretty cool


I have a 4 cylinder 2003 Optima and I'm having all kinds of trouble with it. I got it last year and it had 76000 miles on it. When I bought it, the driver's side rear window didn't work, and the locks were iffy on unlocking with the button. NOW, it has 103000 miles and I need new axles, already had to get a new timing belt, the driver's door lock is broken (can't unlock from the inside OR outside), and the gas tank is screwed up. Don't think I'll ever buy a Kia again.

The auto-unlock is not functioning, but the auto-lock is.


ok the switch on the drivers side not working is the problem,its not allowing the cicuit to be completed.you may want to check the passenger side lock actuator.

My drivers door locks with out reason. When I unlock with my key, I can open all of the doors except the drivers door. If I try to open the drivers door it will lock all of the doors again. The same thing...


seems to be a common problem on 03 kia's. most likely the latch mechanism is worn (they are mostly plastic and pretty cheaply made) and will need to be replaced. It happened to my kia and most mechanics directed me to the electric actuator, but all electircs were ok. drivers door latch went bad about 45k and front passenger door latch went bad about 65k.

Driver and Passenger auto door locks are inop.


Sounds like bad wiring, or bad door lock actuators. Check for power while locking/unlocking the doors.
