Yes, you can reuse your physical Disney Key to the World card (the plastic card that acts as your ticket or room key) for future visits, provided the card is still in good physical condition and is linked to your account. Even if the original tickets on the card have expired, you can link new tickets to your My Disney Experience (WDW) or Disneyland app profile, and the old card will automatically act as the "key" to those new tickets. However, many guests in 2026 have moved toward using MagicBand+ or the "MagicMobile" feature on their smartphones and Apple Watches, as these provide more interactive features like haptic vibrations and light-up effects during shows. If you prefer the physical card, you can continue using it indefinitely as long as the RFID chip inside remains functional and is properly assigned to you in the app.
