I had an alarm and remote start installed in my 2009 Nissan Altima. I visited other shops in the area was told that because I had a push-button start that it would be a longer and more costly installation. I was quoted between 6-7 hours and between 600 to 800 dollars. Autobahn quoted me 4-5 hours and 450 dollars. They did the install in 4 hours. When it came time to demonstrate the operation they were knowledgable and very patient with me. I would definitely reccommend them to everybody and often do. I appreciate the professionalism that they showed me.
