Replace your deadbolt lock with the Advanced Protection Digital Deadbolt Lock from ThinkGeek and you’ll reduce your worry about break-ins. The lock resists lock-picking, kicking, sawing, hammering, and prying. You can unlock with a passcode or use the TagKeys. The TagKeys cannot be duplicated, and they can be deleted from the system if one is lost. This Digital Deadbolt is guaranteed to fit standard American doors and installs with only a Phillips screwdriver. The lock operates for 1 year on a set of batteries (4 AA), so no wiring is necessary. You can set it to automatically lock when the door is closed, so you don’t have to continually worry if you remembered to lock the door as you left for work. The Advanced Protection Digital Deadbolt Lock is $279.99.
