Jumping into this discussion late because I got my 2008 Accord literally 4 days ago and am still finding my way around the owner's manual (and the car). I like the car so far, but I was dismayed to learn that the Accord tops the list of cars most often stolen!
I came home and locked the car up, and sure enough, the security system is set as described on p. 217 of the owner's handbook. When folks in this thread say the anti-theft system, do they mean the ignition switch?
Given the Accord's popularity with chop shops, I'm just a bit nervous about whether this is enough. I understand that thieves deal with door and ignition locks by uprooting them with a dent puller. I note the suggestion about a fuel kill switch, and I'll consider that. I've thought also about VIN etching and some version of The Club.
Thanks for your thoughts.
