end
where secondProductItemCode in('616161911659','611611965166')

Answer 1

MS Access doesn't support CASE . You can use SWITCH() :

UPDATE tblSecondProductItems 
    SET secondProductItemLot = SWITCH(secondProductItemCode = '616161911659', 20,
                                      secondProductItemCode = '611611965166', 21
                                     )
    WHERE secondProductItemCode IN ('616161911659','611611965166')

Answer 2

You can try something like

UPDATE tblSecondProductItems 
CASE
    when secondProductItemCode == '616161911659' then secondProductItemCode = 20
    when secondProductItemCode == '611611965166' then secondProductItemCode = 21
END
WHERE secondProductItemCode in('616161911659','611611965166')
