hie, am newbie and i bought the 370z from japan. 
could anyone tell me what to do if both remote control(i-key)and mechanical key lost? i cant even start the engine even i have tool likes consult3. please advise guys.

Where are you located? You didn't get a spare key?

i'm from east side,singapore. I knew that there are two set of key (keyfob+mechanical key) for new 370z imported from Japan. but, the two set original keys was missing when i first saw my car. what should i know?

I'm not sure about this but I think if you contact Nissan Japan and let them know what happened you should be able to get 2 sets of replacement keys. They will probably just go off of your VIN #.

You will probably have to pay for them and it won't be cheap, but I don't see a problem getting replacements.

thanks bee.

Problem solved with new key ordered Japan.
