Using your current key, insert it into the ignition & turn the ignition to the "On" position but not the "Start" position. Do not start the truck.
Next, using a very small screwdriver (preferably a phillips head) insert it into the hole located under the ignition key cylinder on the steering column.
Pressing upwards with the small screwdriver or nail, you will press in the release button.
Firmly grip the key & ignition cylinder while pressing up on this release button & remove while in the "On" position.
Insert your new ignition cylinder with the key in it, into the "On" position until it snaps in place. Going in, the release button does not need to be depressed.
