Description: The Hyundai NFC Key Card (T1H81-AD001) is a factory-designed digital access key for 2017–2025 Hyundai models. Using near-field communication technology, it unlocks and starts your vehicle by tapping the card to the designated sensor, eliminating the need for a traditional fob. Slim enough to carry in a wallet, it offers the same functionality as a smart key in a modern, minimalist format. A genuine Hyundai OEM accessory.
