How do you remove the ignition key tumbler from your 1995 gmc vandura 5.7?

To remove the ignition key tumbler from a 1995 GMC Vandura 5.7, first ensure the ignition is in the "off" position. Next, insert the key and turn it to the "run" position, then locate the release pin (usually found on the bottom of the ignition switch). Use a small tool to depress this pin while simultaneously pulling the key tumbler out of the ignition switch. Once removed, you can replace it with a new tumbler if needed.
