Lockboxes are secure containers used to store valuable items, documents, or keys. They are often made of durable materials and come with a locking mechanism to prevent unauthorized access. Lockboxes are commonly used in real estate, where agents place keys inside for easy access by potential buyers, while ensuring security. In addition to real estate, lockboxes can be found in various settings, such as hotels for guest room keys or businesses for sensitive documents. They provide a convenient way to manage access while maintaining safety and security for important items.
