In most locations the classrooms will remain unlocked and no key will be necessary.
Laboratories are usually locked, especially if they contain chemicals or equipment. The administrative assistant will furnish affected faculty with a DMACC Key Assignment Card to
complete and sign to gain access to these labs. Outside doors to classroom buildings are typically unlocked during regular class hours. If faculty need access on weekends, keys may be requested. Policies vary by campus, so ask the administrative assistant or dean/provost for details.
