Someone had a scanning device and captured your key code when you locked the door I believe.

That's exactly what my mechanic said also.

Did you call the company that owns the lot to make sure it wasn’t mistakenly towed?

First thing I did, prior to even calling the police.

On Star? Tracking Device? Find My iPad/iPhone?

Tried find ipad to no avail... there were 2 in the truck. Tried OnStar (although I didn't have the service). They said there was nothing they could do.

I can speak to these devices (I’ve built a few for work and for fun)

Basically there are two types, depending on how your car’s ignition works.

If you have a keyless fob that starts your car (e.g., you just walk up and hit the ‘start’ button), attackers can wait for you to park your car and go into the restaurant, shop, whatever. Then they setup relay radios between your car and your location so the car gets your legitimate key fob wireless signal. (Suspect this is what happened to you btw)

The other type executes what’s called a rolljam attack - basically, every key press of your fob has a unique, sequenced randomized code. These codes are synced between your car and your fob when its first synced (and occasionally over time). Since it’s random, attackers can’t just build a radio to guess because of 1) time to guess correct code is statistically unrealistic; and 2) your vehicle is smart enough to basically recognize an attack and reset/ignore all previously issued codes.

So, your car will only answer to one code at a time that is theoretically never used again. However, in case you hit a button while it’s in your pocket or whatever, the car actually recognizes like the next 20 codes that have been programmed.

The rolljam attack works by setting up a listener and a jammer. He jams your car’s receiver for the first button while listening for that code. Your button press won’t work (it was jammed), so you use your fob again and it will work after the jam stops. BUT, that original code WILL still work (almost like backwards compatibility).

There are other problems out there mostly around bad implementation of the crypto (Teslas, Ford Raptors, Jeeps come to mind). It might be possible the OP falls into this category.

Either way, hope insurance comes through for OP - sucks all around.

OP - might be worth a call to Chevy (not your dealership) and see if they’ve had similar reports.
