Owners/service Manual problems of the 2005 Nissan 350Z

I had avital 5303l remote starter/security system installed on my car on 2/8/14 by mobile sound and alarm in pennsauken NJ. When I got home I turned off my car and placed the car in 1st gear (manual transmission) and pulled up the brake. I stepped out of the car and shut the door and hit the start button on the new remote control and the car drove up the curb and crash into the wood beam that holds my desk up in my condo complex and crash into the left wall on the patio of the lower unit. I tried to catch up to the car and once I got the driver door and tried to open it the car stopped. When the car stopped my right foot was trapped under the driver side rear wheel. A passing neighbor had to get into the car start it up and put it in reverse to get my foot from underneath the car. I called the police and had a police report created and reported the incident to my insurance. My foot was not injured. On 2/11/13 I took the car to a very large lot and turned the car off and put the car in 1st gear. I started the car again using the remote starter control and car drove away. I hit the remote start control again and the car came to a stop.
