Door locked by itself - 2007 Sonata

Not difference at all, see:

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 locks.

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.

One word. Titanic

Oh well - if you want to go jumping at shadows because a cartoon dog tells you to, then just go ahead.

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, though.

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.

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?

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 factors.

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.
