need to buy a spare key for my 2001 boxster S

[eliimports]

So first my boxster is 2001,
and i don't live in the US,


I thought maybe to buy a key from the US and sync it here in a local dealership,
because they charge you 350$ for a key than another 200$ for sync and cutting the blade!!
so i cant avoid the 200$ but maybe i can buy the key for less from ebay or something....

thank you shadrach74 for the links ... i checked it ... it will cost me 160$ +-
then i can save 200$ +-

but before i buy it , there is something i need to check before ??
i know there was car keys with 1,2 or 3 buttons... is there more difference that i don't know about?
or it 100% fit to my car?

and is it open also the two trunks?

thanks you all!
