I don't really know that this app will perpetuate a lot more crime - 5 kiosks in NYC actually seems like less availability than your crooked buddy at the hardware store turning a blind eye to you bringing in a key or two every so often.
Plus, it seems to me that use of the app and kiosks is even more trackable than walking into a physical location.
Cloners can be bought from underground websites, the same sites that sell credit cards etc. Look around on Youtube, it's a bit scary how easy it is.
Definitely agree about trackability with the app.
2) The value of contents of my trunk is rarely within two orders of magnitude of the value of my car.
The valet key cannot unlock the glove box, and there is a switch in the glove box to disable the drivers seat trunk switch.
Depends on the model. New cars usually have this, but e.g. older cars like Mazda 626 or VW Bus, up to the new T5 line, do not.
In some cars, it's configurable at order time if you want this feature.
But then again, I don't really like valeting my car anyways.
They always have. It was always possible to take a blank key and just copy it with a file. You could use a softer material to expedite the process and then copy it again later...
Which is why, most cars come with a valet parking key that only turns the ignition, and doesn't open your trunk. You're not supposed to hand the valet your entire keyring. That's ludicrous (although a lot of people do this)
Though with the availability of this app we're going to see a lot more crime committed this way.
