Since we moved to Livermore, my office is in the house (not in seperate building as in Petaluma), I had to find a solution to keep the kids out of my office. A regular lock wouldn't work since I would always have to have my key. This 'Touchpad Electronic Entry Lockset' by Morning Industry Solved that problem. I highly recommend the lock. My wife is getting one fro her office next month.

It works great and has a feature that automatically locks the door again after 10 seconds. No more forgetting to lock the door. My office has never been so clean, and all my projects are undisurbed.

I bought my lock from Smarthome
