NHTSA Complaint #11657508 — 2019 AUDI Q7

As always, my wife put her purse with the key in the purse in the front seat of the car while she was putting our (3) old grandchild in the care seat. as soon as my wife closed the back door all the doors locked, possibly our granddaughter hit the lock with her foot. The back doors only have a lock feature but not an unlock feature. My wife had to call the fire department to get the doors open. We live in Florida, if this was summer, there could have been a health risk to our grandchild. (1) why with the keys in the car would it lock (2) why isn't there a way to unlock the doors from the back seat? I went on line and it looks like others have had this same issue.
