DOES ANYONE HAVE THE STEPS TO replace ignition key cylinder on a 1990 honda civic?

I asked my husband, and he knows how to fix it but says its hard to explain, and he'd need pictures to show you to explain, which he doesn't have.
He says to get an maintenance manual (you can get tham at places like walmart) and it will show you exactly what to do.

If the key will not turn at all most likely you will have to pull the steering wheel and use a harmonic wheel puller. It can be a bit tricky if you don't know how.
