So I'm having some ignition issues with my car that will necessitate ripping out my steering column and replacing the ignition and key at some point this winter. That's an issue for later, but for now the simple issue is this: I can't use my key to engage the starter, it's simply not going to work.

What's the quickest/easiest way to power my starter and get my car started? I need to move to to a better location to do the work on it, and if I can get the starter to crank, the car runs and drives just fine. What would be the easiest way to make this happen?
