All modern cars have been locking the doors for the last 20 years or so, as far as I know. At least here in Western Europe.
The door handles still work from the inside, they mechanically unlock the door unconditionally, meaning nobody can be trapped inside even by manually locking the doors.
The exception is if you flip the "child safety" switch which disconnects the inside door handle of the rear doors.
