I think this door are installed only in WTFland...... nowadays (after the stone age lol) we use the double Z doors and we let them use this in the post just for movies :-D

why not use doorhandle? it's not lockable door

...and if the credit card trick doesn't work, get a paperclip, hairpin or just a piece of thin wire and pick that lock. It shouldn't take you more than 15 seconds even if you've never done it before because that's how they do it in the movies, right?

Any door lock made since the 70's is designed not to allow this.

This does work on any doorknob lock. Which is why you want a deadbolt.

Older then the internet ... They do not make these locks like that anymore FAIL.

You'd be surprised how many doors this will work on... even the ones made to stop it with that lil piece of metal... Most people install them wrong.... just sayin..

My dad did use this many times and did it just last week. So, yes it works!

Just make sure if it breaks off, you haven't just left your name on a piece of plastic in someone else's door. Could be awkward.

Just when we gave up and decided to break the door knob;I googled, found this article, and 2 minutes later the door was open.
