I believe those over wing exits are locked through an electric circuit and can only be opened once the flight deck (or cabin crew?) removes power to the lock, or power is disrupted (crash). So is it not part of the process that for the over wing exits to be opened the crew had to activate the de-lock device?
Emergency doors requiring a flight lock will automatically unlock depending on the aircraft state -- e.g., air/ground mode, throttle position, engine thrust, etc. -- without crew intervention.
