Ok, So I have that EXACT lock and it works perfectly with A+. I also did my pairing from way more than 3 feet away. It took a while to get it working, but following advice from others on this board (for different tools), I did get it to work. The key (no pun intended) was to first set the A+ to remove the sensor (yes, I know it wasn't added yet) and do the same on the lock. Then, go to add it, and it will show up. The only problem is that the through the web interfaces it always shows up as "Unlocked" until I click on the refresh icon.
