Where to get spare keys?

[brizbot]

Greetings!

After spending a week looking for the only key I had for my 2003 Suzuki GZ 250 (which turned out was underneath the seat, luckily I figured out how to remove the bolts on the latch below the gas tank), I realized I should probably make a spare or five.

Any suggestions on how and/or where to get this done?

Thanks for your time
