I had to them install a remote start/ alarm in my car and it NEVER worked correct. It would start and shut off randomly. They told me it was the computer so I paid to have it sent in and checked out and the manufacturer said there was nothing wrong with it. It has been over 2 years and they have had many attempts to fix it with no luck and they still wanted me to pay them for a diagnostic. Stay away from them if you want your system to work right.
