How to remove an ignition lock cylinder on 1991 ford ranger without the keys.

the manuals says

1. Rotate the lock cylinder key to the Lock position. Disconnect the negative battery cable from the battery.
2. For tilt column only, remove the upper extension shroud by squeezing it at the 6 and 12 o'clock positions and popping it free of the retaining plate at the 3 o'clock position.
3. Remove the 2 trim shroud halves by removing the 2 attaching screws.
4. Disconnect the ignition switch electrical connector.
5. Drill out the break-off head bolts connecting the switch to the lock cylinder housing by using a 1/8 in. (3mm) drill bit.
6. Remove the 2 bolts, using an Ex-3 Easy-out® tool or equivalent.
7. Disengage the ignition switch from the actuator pin.

Be sure and watch the first video. Make sure you understand the mechanics of what you are trying to do, first. The first video link is on a Ford. Its not easy to do, but it can be cheap. Just don't slip up and drill too deep. Fortunately you will have the new cylinder to use as a guage for how deep too drill.
Now what I have done is determine where the pins are that actually lock the lock, and just drill those out. Then you can take a large screwdriver and turn the cylinder. Once turned, you can press the button they are talking about in the video and it will release the cylinder. Then just insert the new one in the same position.

Watch the second video to see how to replace the cylinder when you can get the old one to turn.
How To Install Replace Worn Out Sticking Ignition Key lock Cylinder Ford...

It is easier to go to a junk yard and get a steering column that has keys in it. I have done it twice because if you are too far off the new cylinder wont lock into place.

In most cases you will have to drill it.
There are videos on Youtube that show how its done.
Most all Ford locks in the late 80s and early 90s are the same style.

1. Disconnect negative battery cable.
2. Remove lower steering column shroud
3. Turn key to RUN position and press lock cylinder release pin on bottom side of lock cylinder
4. Pull lock cylinder out of steering column.
5. Reverse procedure to install

1. Disconnect the battery ground cable.
   
2. Insert the ignition key into the ignition switch lock cylinder and turn to the RUN position.
   
3. Push the ignition switch lock cylinder release tab with a punch while pulling out the ignition switch lock cylinder. It is the little hole in the side.
   
4. To install, reverse the removal procedure.
   

This is VERY simple.

u must remove the sterering wheel and then the ignition key cylinder lock pin to pull the switch out

put some oil down the barrel where the key goes and then pull and push on the steering wheel in case the steering lock has come on.

You mean the ignition lock cylinder? Turn key on, then look under the column, near the cylinder, there is a small hole, take a small screwdriver or rod and find the small hole about 2 inches from the key and depress the button, the cylinder should pull out.
