Kwikset also sells some programmable models and the nice thing about them is that they can also be easily re-keyed to an existing key. They also integrate with various home automation hubs such as SmartThings (as do the Schlage models). It's all very interesting and futuristic, but I share your concern about hackability. The so-called Internet of Things has a lot of growing up to do with respect to security I fear.
