1.If Key is found update records
2.If key is not found insert the record.

To copy from SourceTable to DesitinationTable:

update  dst
set     col1 = src.col1
from    DestinationTable dst
join    SourceTable src
on      src.Key = dst.Key

insert  DestinationTable 
        (Key, col1)
select  Key
,       col1
from    SourceTable src
where   not exists
        select  *
        from    DestinationTable dst
        where   src.Key = dst.Key
