This is a replacement for your Datsun 240Z, 260Z or 280Z's ignition switch. This is an easy installation -- check out our installation guide. The ignition switch uses two shear bolts as additional protection from theft. This comes with a set of two replacement keys.
Please note that this particular replacement part does not support the key-in-ignition buzzer.
This will fit a 280Z, but not a 280ZX.
