Discreet Keyless Entry. The SimpliciKey Remote Control Electronic Deadbolt is designed to look just like a traditional mechanical lock (it even has a functional keyhole). But the locking mechanism can also be operated by clicking a key fob or punching a code into a keypad concealed beneath a sliding metal cover. Power comes from four AA batteries. The bolt is sold in brass, nickel, and bronze finishes and can be found online (with two key fobs) for $230. SimpliciKey, 703/904-5010, simplicikey.com.
