If you’re going to remove
to check for numbers, would it not be cheaper just to replace the whole thing? Has anyone lived in the house previously who still may have a key for it?

This is 80 year old building. So not so keen to replace all locks as each door got locks and its very solid. I had these keys somehow lost...No way to find previous owners as house changed ownership not very recently. thanks

What I was trying to get at is that any previous owner may have a key and are able to unlock the door to gain entry. Standard practice to replace all external locks when you move into a ‘new’ property

This is internal door only, since its a old house each door got lock

If you want to have a working lock but preserve its appearance you need to remove the spindle and take the lock out of the door.
There will be numbers and letters stamped on the lock case. These tell the model number, not the individual key code.
Go to a supplier such as Lockmonster.

You will be able to buy a new set of levers and matching keys for your model number. Open up the lock, take out the stack of levers and replace with the new ones. This is quite easy to do but there are YouTube videos to guide you.
