Electric door locks seized on 2000 Sonata

Discussion in 'Hyundai Sonata' started by Richard Steinfeld, Jan 27, 2011.

  1. I have twice experienced bizarre electrical seizing of my door
    locks. Issues follow:

    1. The driver's door will not unlock with the key.
    2. Unlocking the passenger door (which typically unlocks all the
    car doors) can't be done. As soon as the key is released, all the
    locks slam latched.
    2. The passenger door can only be unlocked by rotating and
    holding the key in the "open" position and, while the key is
    held, pulling on the door handle. This allows the passenger door
    to be opened.
    3. The driver's door may then be opened with the inside latch.

    Today, this happened for the second time. I noticed that the
    driver's door latch lever was not fully in its "closed" position.
    In recent years, this latch has been a bit sluggish.

    The problem seems to duplicate the "all doors latched" momentary
    switch as if it were continuously pressed. I was wondering if the
    switch button was sticking on some material in the arm rest, but
    it doesn't feel like it's binding on anything.

    The last time this happened, it seemed to me that the battery had
    been partially drained. My car radio's stupid reset alarm was
    beeping, and I found that three of the computer's drive cycle
    monitors were showing an incomplete condition. So, it would sure
    seem that this door lock issue had run the system voltage so low
    to cause these malfunctions.

    I gave the battery a short charge, and everything was normal
    after that. Today, the car started normally after I managed to
    enter it.

    A good one for Click and Clack, huh?

    The issue is in the latch on the driver's door. As it seems to come
    and go, it may just be a lubrication issue. To lubricate well, you'll
    need to remove the door trim panel.

    A similar issue that won't fix itself often occurs when a spring on
    the latch breaks. Given the age of your vehicle, it may be a better
    idea to just go ahead and replace the latch now. If it's broken for
    good, it becomes much harder to open the door.
