Most doors protected by deadbolts fail in one to three kicks. In mere seconds home invaders are inside your house, giving you little time to call 911. Even if you are able to call, the average response time for police is over 7 minutes. In many cases they don’t even have to kick in your door - amateurs using “bump keys” can now easily defeat 90% of deadbolts. Surprisingly, many higher-quality, more expensive locks are often more vulnerable.
