Nice video. One thing to consider…… Many people in this country are armed while traveling (myself included). What is going to be greeting you when you open the door? It will either be a person sleeping or a gun barrel. Is this cute party trick worth the risk?

Oh how clever, home invasion. Now he just needs to figure out a way to deflect bullets using nothing but a rubber band.

Brilliant and simple. For those who think that you can just slide the chain with your hand, go ahead and try. You'll quickly understand the concept of a chain lock.

retarded and uninteresting…
so the person locks his/her hotel door with the chain but NOT the super-magnetic lock thing…okay
2- he had his hand so far in he could have just slid the thing

Of course, the door has to be open 1st. A rubber band is less practical than your hand.

wait…the hand was completely in far enough to just slide the thing over and unlock it.

Yes, but a chain lock - by design - is only “locked” when you are inside the room. So by the time someone has done this, you can have left by the back door, or cut off their hand with a spoon…

Thanks for the tutorial, going to buy a dead bolt now!!!
