You can reenable your WSKey in the WSKey Management portal. From the list of your institution's keys, click to open the desired key, and then click "Enable" on the right side of the screen across from the Status.
Please wait to reenable your key until you are ready to use it. This will help prevent it from being disabled again.
If you have trouble renewing or reactivating your WSKey, please contact OCLC Support with the first 10 digits of the WSKey you need to renew.
