If your KTTW (Key To The World) card is from the past 7 years or less, the assets would be expired. Only exception to that is, if you had tickets on the KTTW card, and they were never used. Unused tickets never expire and they are good to use at a future time. If tickets on the KTTW card were partially used, the remaining days would expire 14 days after first day's ticket was used. The only way to check on the assets of an old KTTW card would be to take it with you to WDW and have it checked at either a park ticket booth or a guest services facility.
