A deadbolt security device clamps onto an interior deadbolt knob and prevents unlocking of the deadbolt door lock even with a key. While clamped onto the deadbolt knob the device has a shaft and a hook that extends around a door handle of the door to completely preventing turning of the deadbolt lock mechanism. This device is comprised of upper and lower clamp members that are movable toward each other to tightly grip the deadbolt interior knob or away from each other to permit easy removal of the device from the door. |
