I have exactly this in my glove box at all times. It can even get you out of other potential issues with the ignition switch and such.

+1. I made a hard wired jumper to bypass mine when it failed in the garage, in the middle of my move to a new house. I had to drive the car, but had only owned a couple of months and had not bought a spare relay yet. The jumper worked so well that I don't have a spare relay, just the hardwire rig, which is always in the glovebox.
