I had a automate aftermarket installed 3 weeks ago and like everybody else my engine shuts off when I grab the handle. But I got a call a couple of days ago and they told me they can keep the engine running and just hit the start button twice to keep the car running. YES. they got it to work.. :D I can start the car unlock my doors and have the trunk open with my aftermarket remote. When the car is not started, all my original functions from the factory remote works as if an aftermarket remote starter was never installed. However, they had to do alot of old school wiring..
