Hey guys I got a 1980 F150 and I have to replace a key cylinder. I got the old one out and have the new one. The old one came out with turning it to a run position and through a pin hole released the cylinder. My question is, I am trying to put the new one in I get it lined up but cannot get it to seat properly only goes about 3/4 way in. Any ideas if I I’m doing something wrong or any tips on how to get it to go in properly. Thanks in advance!
Are you sure the end that goes in is lined up with the part it fits into?
IIRC it is a slot type thing could the truck side moved and now the new key will not slip in?
Not seeing the old & new next to each other and where it needs to go it is hard to say do this or that.
That is all I have for now. Dont know when I can get to my books to see if it has something so keep trying.

If it's only going 3/4 in, then i suspect it's not lined up. If it goes almost all the way in, then it's just bad parts. I had this problem on my 91 Bronco. I bought the cheap lock and it wouldn't seat. I exchanged it, same problem. I bought the more expensive one with the same problem. I knew everything was lining up correctly. I put a micrometer on the end and it was slightly bigger. So i scraped and sanded on the end that goes into the actuator gear until it fit.
It does fit and line up just won’t seat all the way in. I’m going to take a look and see if the new one is thicker on the end maybe that’s why it won’t go. I have a 71 that has the same issue went through 3 different cylinders and still have to start it with a screw driver lol.
Color the end of it with a sharpie. It'll leave witness marks that tell you where it's hitting. The tip is just pot metal so it scrapes and sands easily
