Yup our mechanical key works è same as modern bikes equipped wif an embedded chip inside è black plastic key holder. U can juz duplicate a spare but when u crank ur engine nothin will happen.
For m/cycles we usually will duplicate a spare to open compartments, fuel cap or side panniers while warmin up engine but u cant ignite ur engine wif juz dat ordinary duplicate key...
For bikes it cost abt 40-70 bucks to duplicate chip keys. As for our latio, my advice is go make another i-key ($200++) rather than duplicate è mechanical key. More worth it if u get wat i mean
