Just wondering if anyone has install the RFID Push Button Start System sold at "thecrossfirestore.com"? They are selling a system called Smart RFID Car Engine Alarm Finger Push Starter for around $48 bucks. I have dug through the internet to see if there is a straight forward system for our cars. This one should work being sold at this website but was wondering if anyone has done it in the past. Any information on installation would be greatly appreciated too?
