The University of Iowa is going keyless.
Officials are in the process of changing all the old-fashion locks and installing electronic card access on all exteriors doors on over 100 campus buildings.
Officials say the update has several security and efficiency benefits, but tight finances threaten the project, which started in 2008.
University spokeswoman Ann Rosenthal says about one-third of the buildings have electronic access. She says the installation costs
anywhere from $50,000 to $200,000 per building, depending on the number of doors.
