This door knob has worked perfect for us!  We had a normal lever lock but we left it unlocked.  Our dog learned how to use the lever to gain access to the house.  So we had to start locking the door.  That was a pain because you had to get your key out each time you went in.  With the keypad we can punch in the code and have easy access.  We didn’t want to give up the convenience of the lever which works so well when your hands are full.
