Door locked by itself - 2007 Sonata

There's a big difference in a negative failure and a positive failure.

True, but they are both a failure.

What???

You're a smart guy, I'm sure you'll figure it out sooner or later.

It is an erroneous statement so it isn't possible to figure it out as I can't read your mind.

There are false positives and false negatives, Type 1 and 2 failures also called Type I and II and sometimes called alpha and beta failures, but there are no positive and negative failures.

This reminds me of my father in law. He lives in a very rural area, while we live in the BIG city. He came down and we had to go to K-Mart. We were getting out of the car and I noticed he left the keys in his car. When I mentioned to him that he might want to take his key out and lock the car up, his response to me was " What if someone needs to move it?" I actually LMAO!

It's still that way in my parts. Well, not everywhere, but in most places. Locks are mostly a nuisance, but are being used more and more. -

Sir , it is in so in some parts within the Commonwealth of Australia. On this key thing -you folk must have pointed the bone at me. Happened last night when I got in the car !!

The chain of events went like this

1 unlocked the car with the key rather than the remote . 2 Alarm triggered 3 used remote to stop alarm 4 Entered car as normal started car as reversing the doos locked by themselves ? That has never happened before ( unless I set the auto lock thing via the arm rest )

This may help hyundai tech track down teh cause. could it be a sequence within teh chip that controls this function ? HTH

Where's you FIL live? I'd like to move there.

When I was a kid in rural western Wisconsin all the relatives used to leave their homes unlocked if they were away for less than a day or so. If you visited, and they weren't home, you could leave a note saying you'd see them later or whatever.
