By far the most secure lock I have found. The dual locking bolts really make a much more secure door. I recommend them for any exterior doors. Just be careful about the pin lock on it. Once pushed in its impossible to unlock the door from the outside even with a key. Every lock can fail, but at least with this one it will delay anyone enough to call for help or be ready to counter any attackers.

The Ultimate Lock System Residential 3000 series is a revolutionary, one-of-a-kind door locking system built to be 10 times stronger than any standard deadbolt. Designed with the assistance of NASA Space Alliance Technology Outreach Program (SATOP), the locking system features five levels. Additionally, a "Shock Absorber" positioned between the bar and deadbolt, prevents metal fatigue that could weaken these components. When coupled together, they create an unprecedented defense against home invasions.
