[TriEmbed] Hack to unlock your car

Hi! I just joined this group after borrowing one of the NCSU Library's
Arduino kits and having a blast with it. I'm a sysadmin by trade but
know a little about circuits, having built little gadgets all my life
and holding a Tech Plus ham license. Embedded systems really fire my
imagination and I can see myself getting deeply involved with this
stuff. Looking forward to meeting everyone!
Regarding the car/garage door hacks...
Two years on, I think I now know how thieves have been entering vehicles
using a "mystery device":
So, what are car manufacturers going to do about it? I would be
surprised if the chip in the car that actually does the unlocking could
be software-upgraded (not to mention the key transmitters) and I don't
see the dealers giving away any upgrades unless they're forced to, a la
recall. I bet car manufacturers simply keep quiet and hope no one
notices. At least I don't expect current models "in the field" to be
upgraded with any urgency, which is unfortunate.
After reading this I began wondering how I could tie the OTP app I use
for my online authentication into my car and/or garage door. There's no
rule that you HAVE to use your car's keyfob (or your garage door
transmitter) for access, after all. Each works essentially through a
button switch, right? It would be super easy to replace these vulnerable
systems with a WiFi, 3G, or Bluetooth-enabled device and protect your
stuff with as much security as you can imagine (and implement). The
ignition part, well ... that might be a bigger challenge (or heck, maybe
not. I wonder how truly secure these proximity keys are).
One recent hacking paper I read discussed the transmitters in the tires
of new cars which transmit pressure info (called TPMS
could use those transmitters to trigger the garage door whenever they
were in range of the house, for instance.
