I’m hoping not to get off topic too much. But since we’re talking locks – crime is on topic, right? We live in an area where sophisticated South American gangs hit high end neighborhoods. Happened two streets away recently. They case houses, can get around security systems and are in and out in under 10 minutes, usually when people are out to dinner. They are looking for safes, designer purses, jewelry, and cash. They would be very disappointed if they got in my house.
