Digital locks are a convenient and secure addition to your overall home security system. Some consumers who are hesitant to rely on digital locks take comfort knowing there are physical keys that will still open the door in the event of power loss of forgotten pass codes. Because digital locks are relatively inexpensive and significantly improve the overall safety of your home, be sure to include them in your total security system. With a digital lock system, you won’t need physical keys to enter your home. Because these systems rely on pass codes, you only need to remember the code to enter the house. Most systems will automatically lock when you exit, but you can change the settings so the door only locks with an entered code. You can also use the same code on the front and back door of your house eliminating multiple keys on your key chain. All digital locking systems allow you to use multiple codes. This is especially convenient if you want to track what time the housekeeper shows up to clean or when the kids get home from school. More advanced systems will allow you to set a timeframe for certain codes to work. When you have a housekeeper or repair person coming to your home on a regular basis, you can feel safe knowing that code will only work during specific daytime hours. Digital locks still rely on a physical bolt to keep the door secure. Digital code systems use actuators and motors to engage or disengage the bolt. You can also use a physical key to override the digital system and open the door manually. Commercial security systems have been relying on digital locking systems for years. Thankfully, years of commercial use has eliminated any of the kinks or problems in digital systems making them more reliable for home security than the standard metal key. In just a few short years, house keys may be relegated to the sidelines with home entry dependent on codes, fingerprints, and retinal scans.
