My only complaint with these knobs as well as the lockable knobs I ordered is that they are sold as a set of 2. If you have an odd number of doors, you will have too many knobs. I was confused by this initially and ended up ordered twice as many knobs as I needed, because I did not understand why they would sell door knobs in sets of 2.
I have this located on my garage door to the house. never have to worry about being locked out again. you can even give the password to mom if yo want her to come in while your away. make sure to use fresh batteries for best performance.
