The ignition key cylinder on an Isuzu allows the ignition switch to an electric signal to the starter motor. When the ignition key cylinder fails, you wont be able to turn the ignition key. This is usually because the pins inside the tumbler in the cylinder are jammed or have seized. At this point, all you can do is replace the cylinder. Replacement cylinders are available from most auto parts stores.
Step 1
Slide the punch pin into the small access hole underneath the ignition cylinder on your Isuzu. There is a small release tab on the underside of the cylinder that you must push up on to remove the lock cylinder.
Step 2
Wedge a flat-tip screwdriver underneath the end of the ignition key cylinder.
Pry the cylinder out of the steering column while maintaining upward pressure on the release tab on the cylinder.
Items you will need
