Like XTZ said in his post, I had a key made with the number in the glove compartment after my key broke off when I tried to unlock the door. I got a piece of crap key rather than a Z32 model. Naturally I bought two blanks and had them cut. What pissed me off was that the Z32 keys were cheaper than the one that Nissan sold me.
:My 1992 Prelude got brand new keys cut with just the VIN number and also my mom's 1990 Camry. The Honda dealership said they could do 80's cars. But Nissan can't do Z32's BULLSHIT
