BYD Sea Dolphin Ocean N7 Car Key Cover – Premium NFC-Enabled Protective Shell for Modern EV Owners

Engineered for Precision & Protection

The BYD Sea Dolphin Ocean N7 Car Key Cover is more than just a stylish accessory—it’s a purpose-built, precision-engineered protective shell designed exclusively for the sleek, minimalist key fob of BYD’s groundbreaking electric vehicles. Crafted to match the exact contours of the Sea Dolphin and Ocean N7 key units, this cover ensures seamless fitment without compromising button responsiveness, NFC functionality, or wireless signal transmission. Unlike generic silicone sleeves or bulky third-party cases, this key cover undergoes rigorous dimensional validation—measuring 58.5 × 32.0 × 12.5 mm—to guarantee zero interference with proximity unlocking, remote start, or digital key pairing via BYD App.

Material & Craftsmanship: Where Durability Meets Refinement

Built for daily resilience and long-term elegance, the cover features a dual-layer hybrid construction: an ultra-soft TPU inner lining absorbs impact and prevents micro-scratches, while the outer shell is molded from aerospace-grade polycarbonate infused with UV-stabilized matte finish. This advanced material combo delivers exceptional resistance to yellowing, abrasion, and temperature fluctuations—from -20°C winter commutes to 60°C summer dashboards. Every seam is ultrasonically welded—not glued—ensuring structural integrity over thousands of insertions and removals. The tactile surface features subtle ocean-wave embossing, echoing BYD’s “Ocean” design philosophy while enhancing grip and reducing slippage in wet or gloved-hand conditions.

Design Highlights: Smart Integration, Seamless Aesthetics

This isn’t just a cover—it’s a functional extension of your EV experience. The integrated NFC antenna window is precisely laser-cut and shielded to maintain full compatibility with BYD’s digital key ecosystem, enabling tap-to-unlock, vehicle status checks, and secure sharing via smartphone. A discreet, low-profile cutout preserves LED indicator visibility, so you never miss battery alerts or pairing confirmations. The magnetic closure system uses rare-earth neodymium magnets (N42 grade) for silent, secure snapping—no flaps, no Velcro, no accidental drops. Available in four signature tones—Deep Ocean Blue, Polar White, Midnight Black, and Coral Sand—the palette complements both interior cabin finishes and exterior paint options across the Sea Dolphin and Ocean N7 lineups.

Applicable Scenarios: Designed for Real Life

• Daily Commuting: Protects against keys jostling with coins, phones, or transit cards in crowded bags—while keeping NFC ready for instant access at parking gates or shared mobility hubs.
• Outdoor Adventures: IPX4-rated splash resistance shields against rain, beach mist, or mountain dew—ideal for owners who park outdoors or use their N7 for weekend getaways.
• Professional Settings: The slim, minimalist profile fits effortlessly into slim wallets, jacket pockets, or executive briefcases—no bulk, no compromise on sophistication.
• Gifting & Personalization: Includes optional laser-engraving service (up to 12 characters) for names, initials, or meaningful dates—making it a thoughtful, premium gift for new EV owners, BYD enthusiasts, or eco-conscious professionals.
