NightJumper

Ive seen this talked about before and everything Ive seen is from a few years ago so wondering if anybody has any info on anything newer. What I would like is to be able to have a push start and not need to put my key in the ignition. And I know if not done correctly it could make the car easy to steal but already have a plan for that, just looking to figure out how to get rid of my keys because i hate carrying around keys, would love to carry just a small sensor that unlocks when i get close and then have the push start.
