Looking for a lock for this existing door in my home.

A handy person from Vermont says:
I've got a door that I would like to be able to access with a key, it looks like it could be easily added but I'm not sure where to start. Help us appreciated!

Hello, thank you for posting,

Your handle set and lock resemble the 82-402 set. This style is compatible with the 82-092 key lock that can be adapted to the exterior handle. It does appear that your original exterior handle has the cut out option to install this lock. Take a look and let me know if you have any additional questions!
