Interesting topic. With the cost of new HD Rams it would seem prudent to add some additional security features. I've been looking at various options for a while (my truck is on order). The obvious one that always comes up is: lock your truck and don't leave anything valuable in sight. I've got to believe that the people on this forum already have that one figured out. There are a bunch of YouTube videos that show how easy it is for thiefs to use range extenders to gain access to (and start) a truck. For those unfamiliar with this, it's essentially amplifying the signal between the truck and your key fob. With the range of the key fob extended, the truck "sees" the key fob that is hanging in your house so the thief simply opens the door, starts the truck, and drives it away. Once the engine is started the key fob is no longer needed. Although you get a message on your console that the "key fob has left the vehicle," once the engine is started it no longer needs the key fob to keep going. The truck can be driven to a shop where a computer can be used to rekey the system. The way to prevent this is to use a faraday pouch (inexpensive and readily available on Amazon). But organized crime groups have other, more sophisticated ways of stealing trucks, but at least the faraday pouch makes it more difficult for them and thwarts the less sophisticated outlaws. Ultimately, I think you're trying to make your truck harder to steal so they will go on to an easier target. I've been researching the Ravelco anti-theft system. There is one thread on this forum with a few comments about it. It looks to be very secure but is quite pricy. But, heck, if you've spent upwards to $100k for a truck it might be worth the extra money for peace of mind. There are YouTube videos about installing kill switches - again something very effective but does require some installation and modification work. Another (cheap) alternative is to remove one of the relays under the hood (such as the fuel control relay). The truck won't start without it and it's unlikely that a thief would be carrying a spare. Problem with doing that is that you'd have to get under the hood and pull the relay every time you left the truck. I'm very interested in any comments that people may have about this topic. With my new Ram expected to arrive someday, I'd like to have a plan in place by the time it finally gets here.
