Requires key boxes at public school buildings with certain exceptions; appropriates $2.5 million for reimbursement of costs related to key box installation.*

New Jersey's A5720 requires all public school districts, charter schools, and renaissance school projects to install exterior key boxes meeting safety standards at every school building by June 2027. These key boxes must contain building keys, access devices, and updated emergency access maps, with locations chosen in collaboration with first responders. The state appropriates $2.5 million from the General Fund to reimburse schools for installation costs. The bill directly affects school safety infrastructure and emergency response access.
