    I have a 2007 Santa Fe,and I had something similar happen two days
    ago. Myseft ,The Wife and the teenager went to the local mall for a
    quick bank and milk run.i parked the SF and left the engine running
    and then left the vehicle ,soon to be followed by the wife.

    i got back from getting milk and she the bank and as i sat down she
    states "nice" i say,whats nice...she says "locking me in" i said i did
    no such thing...she says that every time she tried to unlock the car
    to get out that it locked again.they both thought i was in the store
    watching out the window and using the key fob to lock the door when
    she tried to get out.

    I said that i did not do this and was not pranking them which was not
    believed until i pointed out my keys were in the ignition with the fob

    it hasnt happened again...could not duplicate it either...going to be
    a head scratcher trying to figure this one out.

  3. Just a thought, could it be the bank? I wonder if the receiver gets a
    signal from some other source on a nearby frequency and it triggers the door

    A supermarket in town sits high on a hill where you'd expect great radio
    reception. Driving near the end where the bank is, you get lots of
    interference, even at times the bank is open.

    Ed you may be on to something . I tried to replicate your problem
    HEAPS no go.
    I rang the folks who service our Sonatas he said he HAS heard of it
    ONCE but they could find nothing .

    Solution mark IV C -buy a long key chain and clip onto the keys :)
    Then when one get used to taking keys with you (as one should) put a
    watch or dog on the chain:)

    Banks usually have lots of computerized "stuff" - ATMs. computers, cash
    counting equipment, etc. This can interfere with radio reception. The fobs
    used with most modern vehicles - the Hyundais for sure - utilize a series of
    encrypted data bursts. Basically, the data is based on an encryption key
    that is shared between the receiver in the vehicle, and the fob. This is
    typically called "rolling code". The shared key gets determined when the fob
    is paired with the vehicle. There is NO WAY the receiver will mistake
    anything else for an authentic transmission.

    If you're interested.... Hyundai uses
    Omron but they don't explain
    anything, and the principal is the same.

    Nay, the doggy is anecdotally, I do travel, frequently, to Miami, Tampa
    and Orlando and read news from those places ... it ain't pretty at all.

    You guys need to move to Jersey. We're not even supposed to get out of the
    car here. It's ILLEGAL to pump my own gas, although I always do it anyway.
    I even leave the kids AND the keys in the car sometimes.

    Like everything else - it somewhat depends on where you are. Many people do
    not live in high crime areas and just do not have to worry about such
    things. Many people extrapolate from anecdotal incidents that happen in
    high crime areas and attempt to apply them universally. Though I have no
    doubt some things have happened in these areas, I don't for a moment believe
    they are universally the case, even in areas throughout Miami, Tampa and
    Orlando. I have traveled to these areas and I know from firsthand
    experience that none of these experience problems at gas stations as
    described in the cartoon dog comments, throughout their respective regions.
    I certainly believe they can happen, but so can a heart attack.

    Every time I drive into Jersey I get bit by this. Being a NY'er, it's just
    commonplace for us to jump out and fill'er up.

    LOL. Yeah, the first time we drove to VA, many years ago, to see some
    family, I sat there for about 3 minutes before I realized I was supposed
    to do all this work myself :)

    They actually had a sing that siad "No Drive Offs". I assume that meant
    you weren't supposed to leave without paying. Duh.

    Oregon has a ban on fill it yourself, you can get out of the car,

    I thought Oregon repealed that just a few years ago? Well, no matter, I
    was being facitious about getting out of the car in NJ though. You CAN get
    out, just don't touch the pump.

    If I remember correctly, the issue with the Titanic was related to something
    opening - the hull - when it was preferred that that it didn't. The problem
    here is the inverse.
    Bob, Feb 1, 2008
  16. But they said it was unsinkable. The cause does not matter. It sank. You
    say it is impossible for a radio signal to overpower the receiver for the
    remote. How many times have you heard "can't happen" just before the crap
    hit the fan?
    Edwin Pawlowski, Feb 1, 2008
  17. Now THAT has possibilities.

    There's a difference between overpowering the receiver - high power RF
    radiating the electronics directly, inducing voltage in traces in the
    device - and some interfering source being misinterpreted as a valid
    sequence. You mentioned some kind of noise on the FM radio - the suspected
    source being the bank nearby. The receiver is constantly hearing signals on
    315 Mhz that is ignores. Other remotes for cars, garage door transmitters,
    and just plain noise. The decoder needs at least three separate 64 bit
    encrypted sequences to be exactly correct. That just isn't going to happen,
    as I said in my original statement "There is NO WAY the receiver will
    mistake anything else for an authentic transmission". It is possible for a
    failure, or some kind of design defect in the receiver to randomly cause
    these lockouts to occur. Hitting an iceberg with the vehicle could result in
    the doors either opening, or sticking closed depending on a number of

    Yeah, I was hoping someone with kids would pick up on that :)

    No. Hitting an iceberg with a vehicle would cause the vehicle to... sink.
