Could I make a little gun and just walk around through the parking lot and aisles of the supermarket and freeze all the carts in place?

It looks like they’re SubG. The lock signal broadcasts on the buried line, and at least in the one manual I found, they can also lock all, lock all in a lot, and optionally lock singles via serial number (there’s an inventory system). There’s a directional handheld device that can be used within a couple of feet of an affected cart.
