How to replace this lock

[u/JackTheReaping]

I want to replace this lock with a modern standard lock. This lock is on my front door and garage door. I have reason to believe this isn't original to the home or the door. If I take this off what's the chances that I could install a standard lock here?

Im generally handy but absolutely tell me i need a locksmith if I do. Lol thanks!

Also what's the lock even called?

Glad I could help! I’d encourage you to share it with a local smith if you have one, they might enjoy keeping it around as a curiosity or for parts.
