Our scion will automatically lock itself if you unlock it but don’t bother to open the doors. The algorhythm is defective though. One time it locked the keys in the car all by itself. They were sitting on the passenger seat.
I’m now afraid to shut the doors if the keys are in the car in any way, shape or form.
Back in the day you could not lock your keys in the car, you had to physically use the key to lock a door. I missed that feature more than once.
