Z-Wave Yale Real Living Deadbolt
Intelligent door locksets let you open your home with just a few simple swipes on your smartphone or clicks on your computer, doing away with the need to hide a key under that faux rock in the front yard. They're as secure as standard locks, and are wirelessly enabled so you can unlock the door from your phone, if, say, the plumber is scheduled to fix your commode.
Try the Z-Wave Yale Real Living Deadbolt, which is equipped with an intuitive touchscreen. When family members enter the correct code to unlock the door, you'll receive a text message or email to know that they've arrived safely. It can be opened with a key, too, if you're still old school like that. [$275; amazon.com]
