In the past I have disassembled door locks cylinders and removed most of the little leaves so that the key would still turn them. Does anyone think that would that work for the ignition? I never park my car anyplace where I worry about it getting stolen, and it has an original cylinder in place.

I forget now just what I did, but it involved throwing out the worn leaves (pins in most padlocks) and putting things back together. Easy to do and worked great.

Will a cylinder from a door work in the ignition? Maybe thats the question.
