Yeah about 300-350 with labor...i got a viper 800 that was pretty nice...i wrecked my car and took it out, i got an esimate on installing it into a delsol (so it would only be charging for labor) and the sol did not have power locks, so they said 100 for the alarm install, and 60 bucks per door for power locks...if that helps you get an idea of what prices run...

But like pissedpanter said, almost all alarms come with keyless, and accord are an item to be stolen or stolen from specially untinted ones with nice stereos Got my alarm before i would drive mine anywhere when i bought it...but im paranoid...
