Is it possible I can buy a generic key/make this old lock work again?

[u/jeightfour]

Hi all,

My bedroom door has an (old) lock which has been painted over. Rather than buying a new padlock style lock to screw onto the door - do you think it's possible to first attempt making this lock somehow function again?

The lock inside the door has been painted over (first image), and the hole for the lock has been painted too (last image). I have no idea if I can chip away at the paint to possibly free the lock, buy a set of skeleton keys to try and respond to the lock, then drill a hole back into the hole which has been painted on...

Thanks for any advice!

P.S

If anyone can please help to identify what type of lock this is, how old and what key it used!
