A question is what is the purpose? Is it to lock yourself into a room from intruders, give yourself some time to prepare for an assault into the room, or give yourself some passive defense in a hotel or guest home.

As a basic passive deterrent buy a simple $2 door wedge. Kick it under the door frame close to the jam. Regardless if a man is kicking the deadbolt or snapping the chain, the door wont budge back unless its literally ripped from the hinges.

In fact even if the door has no lock, it will be darn near impossible to open the door with the wedge under it.
