Hmmm no, you're thinking of another product from Safety First Secure. This on the other hand temporarily stops your deadbolts ability to turn if someone uses a key, screwdriver or bump key to try to turn the lock open from the outside. From the inside, a child needs only to flip the top off the deadbolt and turn the lock to open the door. It's easy enough a young child of sufficient height can do it.
Yes, this product will work.
