This is at my father in law’s house. I don’t know much about locks but he says that this is an “old type of lock” and it’s hard to replace. So, he’s just ignored it for years. He has other locks on the inside of the door to secure it but I want to fix it for him as a Christmas present. I could replace just the lock or I could replace the entire lock and door handle.
Edit: the key lock doesn’t work and as you can see, the inside dead bolt isn’t even there.
