Dead bolt on a door knob

[Guppy]

I got to make my bedroom more secure, since typical doorknob can be compromised using a plasti card (credit card, gift card, etc). Can I install a kwikset deadbolt throw onto my kwikset doorknob? Yes I understand that I would have to "turn" the door knob in order to latch the door, no more slamming the door. But will this work?

No.

The knob has a limit that only allows the cylinder to turn 90 degrees. And the tailpiece wont mesh correctly with a deadbolt bolt.

You can install a deadbolt into the holes where the doorknob was residing, you will also need to drill the strike hole 1" deep, so the deadbolt will latch all the way

If you're worried about someone loiding (the "credit card trick") the latch, just install a latch guard. Does the door swing into the room or out into the hallway? I'll be happy to recommend one.

A latch guard and making sure the lock is installed correctly will go a long way. The loiding preventor needs to be depressed to work corretly

In layman's terms:

When the door operates properly, the latch (the sloped piece on the edge of the door) slips into the hole in the door jamb (the strike hole). The pin on the back of the latch (deadlocking pin, though others may have a different name for it) rests on the metal plate on the door jamb (the strike). If the pin rests on the metal plate like it is supposed to, it stays pushed in (depressed or engaged). And when the pin is pushed in, the latch can not be pushed back (loided) with a credit card or something similar. The pin prevents the ol' credit card trick.

The problem is that people frequently install the lock and the metal plate improperly. This allows the latch AND pin on the back to slip into the hole in the door jamb. If this happens, the pin doesn't get pushed in, and as a result the latch can easily be pushed back to open the door. You can often tell this is a problem if you shake the door and there is a lot of play/movement in the door.

The takeaway is that if the lock and strike plate are installed properly, a credit card can't open the door. If you see that the pin falls into the hole in the door jamb, remove the metal plate and move it back (to the pin side), until the pin rests on the plate when the door is closed, then screw the plate back in at this position.

Purchase a decent entry latch-set and replace the interior latch set you have now, it unlike a privacy latch-set will have a dead-latch which is a lot tougher to shim versus a standard latch.

You could check & see if Sinifar wants to sell his Weiserbolt, that would be perfect for your bedroom

This. You may be able to purchase the dead latch (WEISER ADJUSTABLE DEADLATCH US4 for Weiser) by itself too. This way, there are no additional holes drilled so the landlord won't freak out, and, as Wayne mentioned, it's way tougher to shim. Maybe some kind of security container is in order.
