Bloke makes a door lock that'll only open if you give the secret knock.

but I can't help but think he's just made it really easy for someone to get into his room and pinch all his stuff.

This is a normal post personally
I'd use it as a novelty on an internal door - not on the main door to my place!

This is a normal post none of my internal doors
have locks on, apart from the bathroom door, and I'm not sure I'd want anyone getting in there with a knock!

Although I can see that it would be suited to say, a drinks cabinet or something.

This is a normal post I thought it'd be good as a sort of secondary lock
So you can use your key to lock the door if you wish, but if you're in your house then your friend or roomate or whoever can just knock rather than having to use a key.

Would be good for shit neighbourhoods; unlocked door which is still protected from shites.

This is a normal post C'mon let's face it
anyone geeky enough to use one of these isn't going to be away for very long.

I wonder how much they cost...?

This is a normal post I suppose you use the key
like you do to lock it in the first place.
