Requires an adult to push the release button on both sides of the lever. This can easily be done with just one hand. A toddler’s hand isn’t as big as yours and he or she will not open the lock. This is a big improvement over other lock designs sold on Amazon. Those only require a single button to be pushed. Clever toddlers and small children can push the single button and open the door. Most kids can’t open our 2-button design. This lets you sleep soundly at night knowing your child is safer from harm.
