Door lock mechanisms have actually been around for a long time, and you might be surprised to learn that the technology really hasn’t changed much in all that time. Someone with something very precious to keep safe, came up with a basic wooden pin-lock cylinder mechanism in Mesopotamia some 6000 years ago. It was opened with a wooden key. What most homes in the US now use is a metal pin-lock cylinder mechanism opened with a metal key. If you are like most homeowners, you likely have a key for your front door. Lately technology is beginning to change the way we lock up. Homes can now be fit with electronic lock mechanisms and some even have biometric sensors instead of keys. If you hate keys, one of these high-tech solutions may be in your future. Combined with new security devices like low-cost video monitors and doorbells that allow you to see and talk to anyone at the front door on your phone, your current lock should continue to serve you well. Maybe for another 6000 years or so?
