how to modify and save locked locked content

Hello everyone. 

I was trying to modify and save locked content but it keeps failing . 

I found 

 dynamicModuleManager.Provider.SuppressSecurityChecks = true;

but it doesn't seem to be overriding the locked part. 

dynamicModuleManager.Provider.SuppressSecurityChecks = true; DynamicContent paperItem = (DynamicContent)dynamicModuleManager.Lifecycle.CheckOut(self); // do stuff paperItem.SetWorkflowStatus(dynamicModuleManager.Provider.ApplicationName, "Published", null); DynamicContent checkedin = (DynamicContent)dynamicModuleManager.Lifecycle.CheckIn(paperItem); versionManager.CreateVersion(checkedin, true); dynamicModuleManager.Lifecycle.Publish(checkedin); TransactionManager.FlushTransaction(transactionName);

above is how i an checking things out , modifying them, creating a version , checking them in and publishing them

Any ideas would be very helpfull

Thanks
