Locked out of my truck "Automatically"

[Service1956]

Today in my driveway, I turned my truck off, got out and shut the door with the keys in the ignition. ( 2011 Avalanche) I was only going to be less than a minute to return. Anyway, as soon as I shut the door, walked away and about 5 seconds later the horn chirped!! Went back and all the doors were locked!!

 

As anyone heard of such a situation?

I've had that happen to me before....but it was because my daughter hit the lock button on accident when she hopped out of the truck.

 

I would definitely check the DIC settings.

My truck is set to do that if I press the lock button once as I get out. Since it has been set that way for nearly 5 years now, I have to pay attention when getting out for something quick. It is such a habit that I have done that with the engine running. Luckily there was a passenger to unlock the door. Also have to remember to always take the keys at gas stations just in case I hit the lock on the way out of the truck by habit.

Is yours set to do the delay lock(that is what it is called)?

That happen to me on a fishing trip. Had to call trip a they got it open with a slim Jim. Hit the lock button by accident when shutting the door. Very easy to do. I had a 07 Avalanche

As stated it's a setting on the DIC, you will need to change that if you don't want that to happen.
