I got a new titanium key, had trouble finding someone willing to cut it Skyline keys apparntly fit the Z.
I was lucky enough to get a titanium key with mine, and I bought an ordinary blank off eBay as a spare. Tony
I got mine off Ebay, 12 bucks a pair then 5 bucks for a locksmith to cut them from my original......lookalike plastic tabbed ones....or get symetrical (not tab style crappy looking ones) from any key shop
i got the titanium.. key also with my zed, as well as a black one and a burgandy one also.. dont know if anyone else had teh same
