How to mark the key of stair passage in property management?

1. First press the key to each suite, and classify the doors and windows by floor and the computer rooms by equipment.

2. Then hang them together with a key chain or string and label the sorting key. Write down the building number, room number or computer room name on the label paper. Owners' (tenants') keys are generally divided into four categories: anti-theft iron gate keys, indoor door keys, electronic intercom door keys, and mailbox keys.

3. Finally, after receiving the building key, the management office will arrange full-time personnel to manage the key. No one can lend it in private name without working, and must go through the registration formalities strictly.
