    My 2002 Hyundai Sonata has a problem with the doors locking. I have driven it for two years before the problem started, but now the doors will lock for no reason at various times (even if the car is off). If the car is running when the doors lock, I have to turn off the ignition, remove the key and use the remote to unlock them (trying to unlock them manually would cause the alarm to go off).

    The first time this happened is when my battery was low. But now it happens regularly. Any ideas?

    Mine does too! Everyone thought I was crazy. I even had to call a tow truck to come and jimmy me into my car because it had locked me out while I was shopping.



    It is very annoying!

    We have the same problem with the 08 Hyundai Sonata. The car is off, keys are removed from the vehicle. A few minutes later, we hear it automatically lock. We are yards away from the car and the remote is not even in our hands.

    This is not a problem, almost all cars these days lock the doors once you start moving or put the car in gear, is this what your car is doing?

    What is the car doing when it happens? (in motion, parked, reverse, off?)

    Do you have a smart key?

We had a similar problem with our 2002 Hyundai Sonata. It got to the point where it almost seemed possesed. Closing the door with the car still running could make the doors lock. Which was a problem. I simply pulled the fuse from the fuse panel under the dash board for the locks. The locks have to be manually operated now but at least we don't have to worry about "phantom locking".

What could be the problem on my 03 hyundai sonata if my automatic trunk opener doesnt work.


I had this problem for awhile too, one day the automatic opener just quit working. My friend fixed it for me. Turns out there's a little lever mechanism on the trunk door, right by the license plate where the locking mechanism is (look up when the trunk is open)... try flipping it and see if the opener will work then. It fixed my problem at least.

My 2003 Hyundai Sonata Door locks will not lock using


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?

Auto Door Locks


Automatic door locks on the 2001 Sonata doesn't exist. The doors are locked manually (by the driver) or by using the Keless Remote. To answer your question, YES, there is a separate relay for each function .. this means there is a relay which LOCKS the doors, and there is a separate relay which UNLOCKS the doors. They are located side-by-side on the I/P junction box (I/P = Instrument Panel).
They are both labeled "Lock", but one "UNLOCKS" while the other one 'LOCKS'.

Passenger automatic lock


Hi There,
You'll have to remove the door panel....Once it's off you can determine where it's getting stuck, which may be on the door panel, then you can rectify the problem.
