A safe-deposit vault is a secure area where individuals and businesses can store valuable items like jewelry, important documents, and cash. There are various synonyms for "safe-deposit vault," some of which include "security deposit box," "safety deposit box," "locked safe," "strongbox," and "vaulted storage." These terms all refer to a secure place for individuals to store their most precious possessions. Financial institutions like banks, credit unions, and other financial institutions commonly offer safe-deposit vaults as services to their customers. Potential customers can generally rent a box or space within a vault, which is accessible only with the use of a key or code provided by the institution.
