I don't believe there has been any change to the security on the 08. Crimestopper makes pretty good alarms and are farely easy to install. The Crimestopper bypass kit is the best on the market for most Nissan's and Honda's. Bypass kits are universal and will work with any alarm. If I were to sell you and install the CS-2016 remote start/alarm with bypass kit you would be looking at about 375-$400 out the door.
