I have had this exact lock for many years (I can’t remember how long I know over 10 years) it is on my back door which is exposed to weather.
Anyway it worked great. I am having to replace it now and bought the same one again. Over the years we have given as Christmas presents to the parents and sibling. Even my 
aunt and uncle had to have one! 
I love not having to carry my key and can even share the code if I need to allow a friend access to get in the house.
The code is easily changed when needed.
