Drunk and lose your house keys and you won’t be able to gain entry into your abode. Or perhaps you’re so trashed you can’t insert said key into said key hole.
Enter the Digital Deadbolt lock. Not only does it feature a keypad that accepts codes ranging from 3-20 characters long, but includes a key fob system. Just swipe the included fob past the sensor and the door will unlock. Each key fob is unique, so in the event one is lost it can be deactivated from the system.
Not only is this thing supposed to be tough as nails strong, but it can lock your door automatically after exit, insuring that your stuff is always safe and secure. 4 AA batteries are required for operation (included) and should last about a year. What happens when they die is a bit unknown, but presumably you’re locked out, or the door unlocks all together (update: there is a back up 9V battery, which hopefully provides enough time to replace the main batteries).
Installation requires a simple Philips head screw driver and cost is a reasonable $280.
