Door lock will not unlock thus door will not open. Door lock will not unlock with the key on either door nor the automatic or manual door lock. This has resulted in having to exit the vehicle from the passenger door. This is sporadic and not on a regular basis.upon searching the internet this is a very common problem across the Kia brand effecting numerous models and years. My main concern is under an emergency, there is no quick/safe way to exit the vehicle.

Once the doors are locked, they can not be unlocked from the inside. The key must be inserted into the drivers side lock cylinder (outside) and manipulated for several minutes back and forth while at the same time pulling on the handle until the right combination of force and timing allow the door to be opened.

It is a well-known issue with Kia Optima cars that the door latch is faulty, and after various lengths of time, it will stop unlocking. By no longer unlocking, I mean under any condition. Using a remote, using the key, even sitting in the vehicle pressing the button on the door or manually moving the indicator by the handle. This is a severe safety issue. In the event of a wreck or other emergency situation, it is impossible to exit the driver's side door on my Kia Optima. No matter what you attempt, the door will not open. When you unlock it using any of the aforementioned methods, the car will automatically re-lock the door as soon as you touch the handle, either interior or exterior. While I can understand normal wear and tear eating away at the component, there is absolutely no reason for the car to default to the lock position in the case of such wear and tear. A simple solution would be to have the latch default to the open position, which will allow persons to exit the vehicle in case of emergency. If this has not already cost individuals their life, I am sure it is only a matter of time. This needs to be corrected immediately, before it costs me my family.

Front drivers side door will not unlock from inside of vehicle. You must use key and toggle lock while holding door nob out in order to unlock door, it may take a while to unlock door while doing this. I have read many responses to others having the same problem with this vehicle. This may be a serious issue if an accident occurs and the door is locked, trapping the driver inside the vehicle.

Driver's side door will not unlock from the inside or outside. This is a major safety concern as someone would not be able to exit the vehicle in a timely manner in case of a fire or vehicle accident. I work as a paramedic and have first hand seen people not being able to exit their vehicles during a fire and it was not pleasant. I did an online search to find how to correct this issue and found thousands of similar complaints through all years and models of Kia vehicles. Even if you don't have enough to mandate a recall on one particular vehicle, I would hope that you look at the manufacturer as a whole and their unwillingness to correct a system wide manufacturing error in their product. Please feel free to contact me if I can provide any further information. Please do something about this before someone is seriously injured, if no one has been killed by this defect yet...

My 2006 Kia opimal driver side door will not unlock.

- Fort Huachuca, AZ, USA

Power door lock on drivers side will not open with the remote button or key. The doors unlock when remote is used, but when you pull the drivers door handle all doors lock. When in car with locked doors, you frequently cannot open the drivers door with door button or handle. In an accident, this door flaw could prevent the driver from escaping quickly. No action has been taken to correct problem to date. I will have the door latch system replaced as soon as possible.

Driver door will not unlock with key or from inside. This problem started randomly. I have to crawl thru passenger door at time to get into my car. After researching online I see that this is a common problem with the vehicle. This is very dangerous should a accident occur and the driver door be locked the driver could be trapped in the vehicle. This is a death trap and Kia should fix it. I called my local Kia dealership to find out if there was a solution to repair this and was told that they would give me a quote on the repairs. The safety of this vehicle is in question and this should be recalled asap.

I have a 2006 Kia Optima and started having problems with the driver's side door not wanting to unlock. The event started Friday afternoon. After working with my door for about 10 minutes, it finally came unlocked. I drove to pick up my daughter and after getting her in on the passenger side, I could not get the driver's side door open. After multiple failed attempts, I had to climb into the car through the passenger side, which is no easy feat to accomplish. I ended up getting stuck in the vehicle until my husband was finally able to work the door open. This is a safety issue because if there was a fire, I would not have been able to promptly exit the vehicle and get my daughter out in a timely manner. Now I cannot lock my doors. I have done research on this defect and have found numerous complaints stating to the same fact. I'm going to try and get this problem looked at but with the number of complaints over the same feature, something has to be done before a life is lost.
