Yes I need a key to start it. When the install was done, I needed to bring in all my keys so they can all be coded properly. And yes, Rallye motors (Smart center Roslyn) is where I bought the car and who did the install. After you've remotely started the car, the doors automatically lock if they werent before, the parking lights go on. When you walk up to the car, you hold the remote start button down again until the door unlocks, you get in the car and put the key in the ignition and turn it to position 1. You step on the brake and off you go. If you step on the brake before inserting the key, the car shuts off. Quite a slick system. You can also shut the car remotely as well if you change your mind.
