I ordered a lock cylinder from NAPA for $62 including key. I guess I'll just have 2 different keys.
I don't want to remove the pins, allowing any key or slender object to start the car. The '95 Civic was the most stolen car in the U.S. for around 10 years. This year it slipped to #2, behind the '89 Camry.
The Haynes manual makes the installation look relatively simple, since I do not have to replace the ignition switch. Originally, I thought I had to replace them both.
Done. The Haynes manual specied that I would need to remove the shear-head bolts. I did not. I also did not remove the steering wheel. After pulling off the covers from the steering column, I removed one safety-torx bolt and used an electrical tester to push in the pin holding the lock cylinder in place. The only other thing I needed was to use a flat-head screwdriver to hold back the spring clip holding it in. The entire elapsed time from beginning to finish: 15 minutes. Now I know why these things are so easy to steal.
Only takes me 2 minutes to get into a locked civic and drive off with it. But I used to work in a Junkyard and would have to open locked Civics that had no keys and drive them if they were drivable I had a lot of practice with that job. It actually helped me to Jimmy-proof my car really well.
