When starting the 95 Integra, it is now difficult to rotate the key to the momentary start position (significant nuisance that is expected to only get worse). The key works fine with the trunk lock or driver-door lock.
This is not an electrical problem and seems to be a mechanical problem with the ignition switch:
I suspect that this has to do with the age and is common for vehicles of age. As such, I suspect the question is ripe: What exactly is the problem with the keyed switch and how can this be corrected?
