ok... so i auto started my 2018 Tahoe Lt because in Texas it’s 100 degrees. Opened the door, put my 3 year old in the her car seat and shut the door. Unbeknownst to me, my keys fell out of my pocket on to the seat. All of a sudden, all of the doors are locked. Freaking out i call a locksmith. Didn’t have onstar activated so thought i was out of luck. CAR THEN SHUTS OFF AFTER 10 min. Probably standard. I call onstar and they help me out due to emergency. BUT HOW DOES THIS HAPPEN WITH MY KEYS IN THE CAR?? should i take it in and ask? Thanks for any help. Never been more scared in my life. My daughter was trapped for 20 min and was really hot but checked out ok. Almost bashed out a window but i thought locksmith would be there quick. Thanks for any advice.
