"Parking valets suddenly require a ludicrous level of trust"
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.
Many (most?) modern cars also have a radio-based transponder fob to operate the immobilizer, which, being both electronic and obfuscated / proprietary, isn't as easy to clone.
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.
It's not the car key that I'm worried about people cloning. It's the droves of people who leave their house keys attached to the keyring when they hand it to the valet.
My Honda has a lockout that disables the lever used to open the trunk from the driver's seat. Of course, many cars have a fold down rear seat (mine doesn't) meaning any valet that really wants to check out your trunk will still be able to.
My 15 year old Honda has locks on all of those things, that you cannot unlock with the valet key. There is a lock on the trunk lever, a lock on the shelf in the back window for the seats, and a lock inside the armrest cubby in the back for the fold-down cup-holder stowaway door thinger.
I think a lot of cars have some kind of lockout for it. I have a VW, and there's a electric trunk lever in the driver side door, which has a keyhole above it to disable it. Both sides of the rear seat also fold down to allow trunk access, and both sides also have keyholes to lock them out. So I guess you could keep the valet out of your trunk, if you actually remember the valet key and go to the trouble of locking 3 different locks. Which gets to your second point, that I don't really have anything there worth caring about anyways. Maybe if they really want to steal my spare tire or something.
But then again, I don't really like valeting my car anyways.
