Oh, I know actually /doing/ it isn’t difficult, but since we rent, we cannot arbitrarily change them. And even if we could, we can’t change the locks on the apartment building itself, so he still has access Thank you ❤️

Yea the main door is out of the picture😕 I rent myself. Keep the original lock and put it back in place when moving out, then no one should be able to give you any shit for it right? As least that’s the way it is here 😅 and it gave me so much security knowing the prev.tenant had no copy and way in🔒
