I have had the August dead bolt for lock for over a year now and have had some issues with the lock not unlocking when i came home.  I reset the parameters in hopes that the lock would automatically unlock but it only worked about 50 percent if the time. So i ordered the key pad and it came in.  It was very simple to install and very easy to program. No more juggling with my keys and getting mad.  Just that simple,  punch in my code and voila, I'm in.  Thank you for reading.  I'll still recommend this ti all of my friends because it is awesome.
