I found this ebay auction claiming it has blank keys for the gs500.

Will this fit my '06? I only have one key right now and I am known for being bad at misplacing them. Thanks!

i got my local locksmith to make a bunch (10-12) copies of my oem suzuki key. i think it was $23 total. don't remember. don't remember how many i had made now, but everyone i know has one, just in case.

i found my one and only oem suzuki key in my sister's flower box (tahnks sis !) 1 1/2 years after buying the bike. it was fine, no corrosion, still use it !

looks like mine only uncut.
