So, in the short term, should I just have a locksmith put in cheap locks all the way around and then I'll swap them out when I put in the new doors?

I also have heard of some landlords that prefer to have these types of items covered by the landlord since it increases the odds of the tenant actually swapping the filters out or refilling the salt in this case.I assume it's a pretty minor expense, so if your lease doesn't indicate, then I'd have a discussion with the tenant and if they push back you could pay for the salt to drop off to them, and then make sure to update your lease before you renew or resign a new tenant.
