How do you remove the lock cylinder from a Datsun 240z ignition assembly?

To remove the lock cylinder from a Datsun 240Z ignition assembly, first, ensure the ignition is in the "Off" position. Locate the small pin or release tab on the side of the ignition switch housing; you may need to insert a small tool, like a paperclip, to press down on it. While holding the pin down, turn the key to the "On" position and gently pull the lock cylinder out of the ignition assembly. Always refer to a service manual for specific details related to your model year.
