Going to look at a low mileage 4.0 tomorrow to replace mine that just blew. Guy lost the keys but says it's low mileage and ran great but obviously, I can't verify that without starting it. Any way to do that without the original key? Can I take the key from mine and somehow trick the computer into starting? Sounds like I'm asking how to steal a car I bet lol but I just need a way to verify mileage and possibly hear it run to listen for any ticks, etc.
