# Update Amazon EBS snapshot lock settings
<a name="update-snapshot-lock"></a>

The allowed updates depend on the lock state:
+ `governance` — you can change the lock mode and increase or decrease the lock duration or expiration date.
+ `compliance-cooloff` — you can change the lock mode, increase or decrease the cooling-off period, and increase or decrease the lock duration or expiration date.
+ `compliance` — you can only increase the lock duration or expiration date.
