Is it possible to remap ISO keyboard to ANSI?

I never had an ISO keyboard and it feels awkward to use. Unfortunately there was no ANSI mac to buy for me so I had to go with the ISO variant. And it's okay: I can get used to the tall enter and stuff, but what bugs me most is that instead of the `~ key I have §±. My question is following: is there any way I can remap it so my 30+ years habit of using this key to open console etc would not result in frustration?
