Are Honda Fits vulnerable to a mystery device?
 

I'd be surprised if anybody here really knows. The device I'm talking about is used to steal cars with. Car and Driver did a write up about it without telling you too many details here Car-Theft ?Mystery Device?: Guarding against a Potential Problem, Real or Imagined ?*Feature ?*Car and Driver | Car and Driver Blog

I don't see why it WOULDN'T be vulnerable, but really who would want to steal one when there are much more expensive targets out there.

This blog post makes it seem legit:

The Club is a really good idea.

Tech savy theives are not going to want to messing with traditionally effective deterence device.

Well, they might be able to open your doors, but they won't be able to start and steal the entire car unless you have push to start. traditional keys ftw
