Keychains, also known as key rings or key chains, are portable decorative items used to hang keys. Common materials include metal, leather, plastic, rubber, and wood, combining practicality and aesthetics. Their designs encompass cartoon characters, brand logos, and realistic models, and they are widely used in corporate promotions, souvenirs, and everyday accessories. Keychains can be categorized by purpose into decorative and functional types: standard types, such as couple keychains made of zinc alloy and available for laser customization, and car logo keychains with rust-proof treatment as promotional gifts for automobiles; functional types include crystal keychains, solar-powered flashing keychains, and other specially designed products.
With the development of the automotive industry, the car keychain industry has formed a complete industrial chain. Products are transforming from traditional mechanical models to intelligent models integrating smart chips, incorporating GPS, Bluetooth, and NFC modules to support real-time positioning and smartphone connectivity. Production processes are trending towards automation and personalized customization. High-end products use materials such as metal and leather and offer limited editions and co-branded models. Brands like Porsche offer choices for the upper and lower shell materials of keychains and customization services for the lanyard text, with dozens of combination options available. Customization services for shape, color, and pattern are also offered to meet the diverse needs of the international market. In 2025, the electric vehicle keychain market saw innovative materials such as natural peach wood carving and top-grain cowhide tanning, and launched combined designs integrating functions such as LED turbochargers, compasses, and thermometers.
