Regenerate a Meta Key {#keys-meta-regenerate}
=============================================

When any security key expires, it must be updated. If you update the meta key manually, you must reassign merchants to it, which can be time-consuming. Meta key regeneration enables you to update the meta key with all of its assignments intact, streamlining the process.

1. On the left navigation panel, choose ![](/content/dam/new-documentation/documentation/en-us/common/images/ebc/ebc-icon-pymt-config.svg/jcr:content/renditions/original) **Payment Configuration \> Key Management**.  
   The Key Management page appears.
2. Use the Search Filters to find the key you want to regenerate.  
   Results appear in the Search Results table.
3. Click the **Regenerate meta key** button for the key you want to regenerate.  
   The Key Generation page opens. The new key appears on the screen. The original key remains active until its original expiration date.

4. Provide the new key details to the merchants associated with the affected MIDs, and instruct them to update the information wherever it is used.
