Subject: In NYC, once a payphone, soon a superfast Wi-Fi hub Message-ID: <email@example.com> By Ben Fox Rubin, Cnet, November 17, 2014 As part of the $200 million project, the first new hubs are expected to come online in late 2015. New York City plans to turn its lowly public payphone network into what it claims will be the biggest and fastest free municipal Wi-Fi network in the world. City leaders revealed the $200 million plan, called LinkNYC, on Monday at City Hall. The project will replace the Big Apple's thousands of payphone installations with thin, sleek, 9.5-foot hubs providing unlimited Internet access at super-high speeds of up to 1 gigabit per second. http://www.cnet.com/news/nyc-plans-to-reboot-payphones-into-superfast-wi-fi-hubs/?tag=nl.e404&s_cid=e404&ttag=e404&ftag=CAD1acfa04 -or- http://tinyurl.com/q77zg4c Neal McLain|

The "modern" style of these has a small electronic module that
contains the RFID device and remote lock transmitter. If you take
your key apart to change the battery, you'll have to pull the module
out to get to the battery (which is just a standard CR2xxx). My new
car, which has keyless ignition, allows the physical key to be
separated from the transmitter, rather than having a separate valet
key -- the transmitter is the only part required to operate the
vehicle, with the physical key only being used to lock and unlock the
trunk and glove compartment.
I haven't yet seen whether there's an issue in areas with high
incident RF, but I've had rental cars before with keyless ignition and
haven't noted any particular problems.

Well, it shouldn't actually be possible to duplicate the electronic
portions of the key -- if the car companies have implemented it right,
which I doubt they have. The way it's supposed to work is that the
dealer (or locksmith) gets a brand new key, cuts it for the physical
bits, and then runs a special rekeying procedure on the car itself to
tell it to recognize the new key (and which driver number it
corresponds to, for cars that have driver-specific settings). This
procedure generally requires at least one of the factory-supplied keys
to be in working order so that the new key can be authorized, but of
course that's not always possible so there must be some sort of
backdoor built in for factory-authorized service technicians.
Presumably they can always reflash whichever control computer is
responsible for managing this function.
There have from time to time been citizen initiatives in various
states, generally described as "right to repair", that would force car
makers to give the necessary reprogramming information and blank keys
(and/or cryptographic material, if they've done a competent job) to
independent service shops -- which the makers don't want to do for
fear of misuse.
