a key.......sometimes
(IMPROVED)
Depending on the type of lock there will be either pins and springs, or springs and wafers. Sometimes there's plastic or rubber grommets and occasionally lubricant or grease.
As long as the door is locked on the outside, the inside door lock of a keyed doorknob will also always be locked from the inside.
The door does not lock with the "door lock" button from the inside to prevent locking your key inside of the car. Simply turn the key in the door when you close it to lock all the doors.
The lock mechanism is broken. Can you keep it lock from inside the car?
No, Because the locked locker is locked with the same lock on the outside, and there is only one lock, so the locked locker couldn't contain a lock if it's locked with it. Unless the locked locker is locked from the inside, then that is possible.
If the door on a Hyundai Gl will not open from the inside, the child safety lock mechanism should be checked. The lock mechanism is found inside the door jab underneath a label that says 'child lock'.
I think I know what your problem is...You can't lock the car door when you're inside because the lock won't go down all the way....Next time try pulling the handle and then pushing the lock button on the inside of the car...It'll lock the door as you're stepping out of it...Most civics have it for a safety reason...

The lock has a clip on the inside, pull the clip off and the lock will come out, remove the lock rod and then you can use a screwdriver to open the lock.
Inside and out of the reach of children.
Remove the door panel, find and repair the lock linkgage.
I had the same thing happen to me. You actually have to push out(with the rod) on the manual lock located right below the electric lock.
Depending on the year, make, and model of the car...but generally, you have to remove the inside door panel and there is usually some form of linkage attached to the lock, and a clip of some sort securing the lock cylinder to the inside of the door.
