Replacing ignition without rekeying

Symptoms on an Accord were: steering wheel wouldn't unlock and key wouldn't turn. After pulling out the original lock cylinder and removing a stuck wafer, I verified the steering wheel lock mechanism was bad as it still wouldn't unlock the wheel.

Accord ignition assemblies with a generic set of keys (that we swap out for the originals, and reuse the original immobilizer) are available for $30, but not so much for Integra. However, one could feasibly use a similar year junkyard piece and swap the cylinder lock using this method if anyone could verify they are constructed the same way.

This would allow you to use the original immobilizer (as applicable) and key. A lot of times if it's not the steering wheel lock it's just a stuck wafer that can be removed (for a marginal reduction in security against a pick). I believe this probably applies to door locks as well.

As seen in the video, there is a small barrel pin that holds the lock cylinder in place. I was able to remove with the right size drill bit. I inserted the bit into the pin until it caught the pin and pulled it out with a pair of pliers. I reused it and the original steering column bolts that I dremeled some slots into for a screwdriver.

All told I spent $30 and a few hours on a job quoted at $1600 at Honda. If anyone can verify Integra lock mechanisms are constructed in a similar way, I'm happy to expand the guide with photos and better details.

Nice write up, thank you for sharing your knowledge back to the community.

An item I had to replace a few times over `~20yrs was the ignition harness. If one is already in there, it might be worth inspecting or replacing.

Thanks, I can definitely expand it as needed, once I verify it's similar for Integra. Majority of the credit goes to the makers of the YouTube video that contains the knowledge all of this hinges upon.

I think it's prudent to replace ignition harness while you're at it, and those are available cheaply. I believe in that case the symptoms would be the steering wheel lock and key function as usual, but the dash lights may or may not come on in ACC position, and the engine might not even try turning over.
