Problem with Composite PK

I'm trying to limit an INSERT Statement to only insert rows into the destination table where they don't match the PK. I understand how I can do this using the code below but it doesn't account for a composite key. Any suggestions?

insert into dbo.Destination (col1, col2, ...)
select col1, col2, ...
from dbo.Source s
where not exists (select * from dbo.Destination d
where d.PrimaryKey = s.PrimaryKey)


Thanks,

Rich Kramp
