Doubly so if you rely on highly-skilled, highly-compensated employees. They know they can get other -- usually better -- jobs and can weather a few months of unplanned vacation.

There is some incentive to track things like who unlocked which doors when, and to be able to instantly revoke access to specific areas of campus under certain conditions (such as a lockdown). Keys don't do that. Moreover, keys present a security hazard that is difficult to address when they are lost or stolen -- especially when the keys allow access to a building rather than to a single dorm room.

The real question is whether locking or unlocking doors ought be done with a chipped student ID card (as is current practice on many campuses) or with a phone+app combo. There are advantages and disadvantages to each of these. But a modern campus's security demands measure's that keys simply can't provide.

I'm a member of a college athletics committee, and I can tell you with all confidence that while is the common perception of college and university football programs, it simply isn't true. Even in Division I institutions football teams are, as a rule, largely funded by state dollars, student fees, and creative tax exemptions rather than by ticket sales, television contracts, etc. And this has been shown in study after study -- it's even a line that the NCAA toes.

You can check NCAA financial disclosures to verify this at http://www2.indystar.com/NCAA_financial_reports/ thanks to a study completed by Mark Alesia in 2006, but a quick Google should point you to a bunch of other studies that give this position the lie. If you'd rather not click through and see the reports yourself, this is a nice summary statement:

"First off, he [Alesia] found that athletic departments at taxpayer-funded universities nationwide receive more than $1 billion in student fees and general school funds and services, and that without such outside funding, fewer than 10 percent of athletic departments would have been able to support themselves with ticket sales, television contracts and other revenue-generating sports sources. In fact, most would have lost more than $5 million."

While this is a statement about athletics programs in general rather than football programs specifically, the NCAA financial reports make it clear that even among popular sports like basketball and football, the overwhelming majority of programs are perennial money losers.
