Wrong, will never work, unless you get the metal molten gravity will not do any thing for you,
Go to a locksmith and get some new ones cut,
If you bought the keys for display then youve bought some duff ones as no-one buys bent keys to look at,
Otherwise heat to a dul read and then on a hard flat metal surface gently tap the bits flat with a hamer but seriously theres more involved than that and if you have little to no metal working skills i suggest you seriously give this idea up as somthign you can do at home,
