lion of the Counts, later Dukes, of Berg (originally the symbol of Limburg) and keys referring to locksmithing, a traditional industry in Velbert. After 1975 a new coat of arms was created that included heraldic symbols for all three formerly independent towns. The key, referring to Velbert's main traditional industry, was retained with a simpler design. Langenberg is represented by an oak leaf, referring to the oak in the old arms of Langenberg. The chevrons in the bit of the key refer to the coat of arms of the lords of Hardenberg, from the coat of arms of Neviges.
