90-93 z's had titanium keys. When you bought your Z, you got a titanium key that opened all locks and you a titanium-esque key with a brown handle that could not open the trunk or glove compartment. I love the Titanium key but I don't even use it? I'm scared of just losing it. It costs like $400-600 to get a new one. I just use a copy key and I framed my Titanium key. Rock on, BlueThunderZ
