Keys locking in Tahoe

[morriskb]

If you had your second fob on you when exiting the vehicle, it will auto lock EVEN if the other fob is inside the vehicle. And yes, it will give you the triple chirp too, but give it 5 seconds and it’ll lock.

I tried it last night. Sitting in the Driver's seat with the doors locked, Key Fob in my pocket, I rolled down the window and tried to open the door. It was locked. That is good and what I hoped would be the case. I feel more secure now.
