Depends on how much and the key you mention is low/no risk.

Only a few things to do with that particular requirement.

The amount makes a big difference. I like to buy stock and write calls against it. If it goes up, great, goes down the calls cover some of the drawdown.

Only thing risk free is buying US treasuries which suck for return and will get killed by inflation.

Annuities = Barf... Salesman get a huge front end commission and the returns are crap. When the market goes up 25% and you get your 6-7%... not so great. Even the downside in some is not limited.
