I had no clue my car had this "feature" that could be so dangerous
I called Toyota, and they said it is a feature that makes it where if you don't open the driver door, it will Re Lock in 60 seconds. They have the ability to remove that sensor so I took it right in. I don't know how many times I have forgotten my keys in the backseat after buckling him in. I guess I usually do open the driver door, but not every time. I would really freak if I actually locked my son in with the kiddo in there, so I wanted that feature gone.
