Hi there, Haylee, and welcome to planDisney!
Thanks for stopping by with your question! It's always nice to see another Magic Key holder here and I hope you've been able to return to the Disneyland Resort again and again with your Pass. I've had mine since the program first began and I've been very happy with it.
In response to your question, I've spoken to a Cast Member about this before and they informed me that you may indeed have multiple
Magic Key Passes attached to your Disneyland account. Your present Magic Key will continue to function as it has and expire on its normal expiration date. If you decide to purchase a new Magic Key, you will have one year to activate it as per the
Terms and Conditions. As long as you don't mark it as a renewal, it should be kept separate from your current Magic Key.
At the time of this writing, Magic Keys are still on sale, so I wish you the best in your purchase decision. Don't forget to always check the Magic Key Portal in the
Disneyland Mobile App whenever you visit. I've found some of my favorite souvenirs that way and I love the special Magic Key holder merchandise they offer to us!
I hope that helps you, Haylee. Please don't hesitate to come by anytime you have more questions for us. We'd love to hear from you in the future and I hope that your next trip to the Disneyland Resort is truly magical!
Wishing You a Great, Big, Beautiful Tomorrow!
