For additional security, the Hills Plaza keying system is based on a restricted keyway. Tenants have building access and elevator access to their respective suites with an access card. Notify the Management Office for additional keys for new employees and to cancel keys for former employees. Access cards can be ordered only from the Management Office: new access cards $30, reprogrammed cards $10. Also, requests for additional locks and for lock changes are to be addressed to the Management Office. No additional locks are to be installed on the property without the written consent of the Management Office. Please notify the Management Office ASAP if you lose your access card.
