No photo attached. Generally all hardware coordinates but doesn't necessarily match- often the front door has a handle where everything else has a knob for instance.

When we built our house, all entrance doors (including the service door to the garage and the door from the garage into the house) were matching styles/finishes. That was 15 years ago…now we’ve replaced the door handle/lock on the service door to one with a keypad…same finish (brushed nickel). We had to replace the handset from the garage into the house; couldn’t find an exact style match but it’s close enough (same finish).
I think you could do either but I do recommend a keypad lock as an alternate for one entry door. Useful when you want to provide access for a short period of time (example, my pet sitter has a different access code than family members) and it can be changed.

Thank you both. I’m making it black but not the same. That’s what my instincts told me to do but I was uncertain. Thanks!
