I just got a '06 Accord EX sedan. In reading the manual, it has some kind of anti-theft system in it. And it says you should not add or alter the system. I wanted to put in a Viper Responder in it, would this be possible or is it advised not to do this and mess with it?

 

Does the car have an immobilizer system? A little green key light on the instrument cluster?

 

Yes, it does, it blinks when I turn off the car.
