Why does my '07 Tahoe lock and set the alarm on its own

[renotahoe]

My 2007 Tahoe recently started to lock the doors and set the alarm without pushing the key Fob. This has unfortunatly locked my keys in the car twice already.

Has anyone else seen or experienced this before?

Thanks

not at all, i haven't heard any reports of this either (but i'm only on this forum) -- i'd take it to chevy, maybe they can reflash the ecu or something?

Is it a stock alarm or aftermarket?

That's a problem for you, take it to the dealer!

Most of the vehicles that I have own with a stock "alarm" will lock themselves if you unlock the doors but don't open them after a few minutes.

I could be wrong about this, but by design and under specific conditions, you're supposed to be unable to lock the doors with the key in the ignition. I know mine my locks pop back up it I attempt to lock them while stopped and out of the vehicle.

I think this is a setting in the Driver's Information Center(DIC) called DELAY DOOR LOCK. Its in the owners manual on page 3-77. It says when enabled, it will automatically lock the doors about 5 secs after the last door is closed, but the key has to be out of the ignition.

My moms 08' Burban does this you can set the time and the doors will automatically lock after a delay but they will NOT lock with the keys in the ignition.
