Just curious - i don't know much on this subject..
How are thieves getting into a locked trx and just driving off without a key?
are they using a flatbed or do they have some sort of fake key?
One of two methods.
1 - signal repeater. If the actual key fob is in the vicinity (like, hanging on a hook just inside your front door), a two-man team can "capture" the signal from your key fob (which is broadcasting all the time) by way of a hand-held device with a big antenna attached to it, and "repeat" that signal to a device the second guy is holding right outside your truck... such that the truck "thinks" the key fob is right outside the truck. The passive entry is enabled, thief opens door, and starts the truck as normal (because the truck "thinks" the fob is close by). Once started, the fob can go away - the truck will stay running and driveable. They just can't shut it off until they get to where they're going.
2 - key programmer. First, they gain entry to the vehicle. Either by breaking a window, or drilling a small hole in the window and using a small tool (screwdriver) to pop up the door lock pin, or by breaking the sliding glass on the rear window.
Next, they pop the headlight switch off (no tools needed), which gives them access to the CAN bus hub that lives behind the switch. Using a laptop with a special cable, they plug into that hub, and now the laptop can talk to the computer(s) in the truck. They run a program, which easily bypasses what little "security" exists in the factory computers (read that as "none"), enter the RF Hub module, delete the existing key fobs programmed in there, and program a new one that they already have. Now their fob is "authorized" by the truck, and they start it normally and drive it away. They can shut it off, and restart it as often as they like, because they now possess an "authorized" key fob.
In either method, an experienced thief (or crew) can LITERALLY be "Gone in 60 Seconds". Factory security is no security at all. Do SOMETHING to protect your vehicle. Bluetooth-based GPS tracking tags do nothing to prevent thefts. Kill switches thwart amateur thieves. Dongle-type security systems thwart the amateurs, and slow down the more proficient thieves. CAN bus immobilizers prevent most all thieves except those with a flatbed. Relocated horns and a shock/tilt/glass break sensor will at least create a lot of racket while they're winching the truck up onto said flatbed. An aftermarket GPS tracking system could at least improve your chances of recovering the vehicle should it be flat-bedded, provided you get promptly notified that said theft is occurring.
(How'd I do with not mentioning any specific product?)
