1990 Ford F150 Pickup Truck,Changing The Ignition Lock Cylinder And Keys

This repair is similar for many of the Ford trucks and vans of this era. It is very simple to do as long as the key will still switch on and the electrical portion of the ignition switch is properly adjusted. First switch the ignition on and locate the access hole for the release pin. Then using a small rod, push in on the retaining pin. You should feel it move in about an 1/8″ of an inch.

Once the pin is pushed in simply pull on the lock cylinder assembly and remove.

To install line up the notches and push the new cylinder back in and turn the key off.

If the pin pushes in but the lock cylinder will not pull out, you may have to loosen the electrical portion of the ignition switch located further down the column. I had to do this in order to remove this one and yes, I realise that I am showing pictures of removing and installing the same new lock cylinder in all of the pictures. Just the way it works out sometimes.

If you have to get to the electrical portion of the ignition switch, it is located above the aluminum plate show in the picture. Remove the 6 bolts holding the bracket on and the steering column will drop down and you will find the switch on the left side of the column. It is held in place by two nuts.

  3. I am trying to rewire to a unviersal switch. I am kind if cinfused on how to do this. My husband bore down into the core I guess you call it and we used a screw driver for a while. I love this truck and want to get it started right away!! help my 73 year old g-pa is helping me.

  4. You may have to loosen the electrical part of the ignition switch, like I did in the post above. You also could just find the linkage and move it just a little to allow the lock cylinder to go into place.
