The Bylaws require that each owner supply the Association with a working set of keys for emergency access and to perform other necessary duties. The keys are not a lock-out service, however, if you have provided the office with a key, the on-site manager can give you access to your unit during office hours. If your front and rear doors are keyed differently, you may want to provide both keys to the office in case an emergency blocks one door.
Mailbox keys are solely the responsibility of the Unit Owner. Neither the Association nor the Postal Service has a key for your individual mailbox. If your key is lost, the safest recourse is to replace the mailbox lock using the services of a locksmith.
