Lockitron is a keyless security system that allows you to access your home sans keys. All you need is your phone and an Internet connection. Using the intuitive app, simply tap the unlock icon to unlock your door and tap the lock icon to lock your door from anywhere in the world. So if you're on the road and suddenly remembered that you left the door unlocked, there's no need to turn around. Lockitron provides peace of mind, letting you see if your door is locked and if it was unlocked by a friend or family member, whether they use their phone or key. You decide who has access to your Lockitron – just enter each person's phone number or email address and you're all set.
Lockitron is compatible with most common deadbolts, fitting over the inside of your current lock in seconds. Using the included Phillips head screwdriver, loosen your deadbolt and slide the included backplate between the deadbolt and the door. Tighten the screws, attach on the rest of the system, and twist to tighten. You can take Lockitron with you when you move, so it's suitable for renters as well.
Lockitron connects to the Internet via built-in Wi-Fi and also works with NFC. Because it can be controlled via app or mobile, it is compatible with any smartphone. Even older phones can use Lockitron through text message commands. In addition, iPhone 4S and iPhone 5 users can simply walk up to the door to unlock it using Bluetooth 4.0. And with intelligent power management, you don't have to change the batteries for up to a year, and you'll get a notification when it's time. Lockitron uses the same encryption as online banking. In case you lose your phone, you can disable its access by resetting your account password.
Lockitron has been featured in The New York Times, Wired, and Popular Science, among others. You can reserve one for $179.
