Not to panic anybody, but I just came across this article talking about an encryption vulnerability in DST80 (it’s what the ‘09-15 Toyota’s keys use for proximity security):
Encryption flaws in a common anti-theft feature expose vehicles from major manufacturers.

It’s not an easy hack but, given the relative value, scarcity, and amount of customization of our vehicles, it might make sense to consider some sort of additional security. Here’s a list of the affected vehicles:
There may be some selective understanding of what was published going on here - I might be one of them; but here are some key sentences that lead me to believe that vehicles with push-button start (i.e. ALL our LC200/LX570 vehicles) are not vulnerable[Emphasis mine]:
"Now it turns out that many millions of other cars that use chip-enabled mechanical keys are also vulnerable to high-tech theft."
"By contrast, the cloning attack the Birmingham and KU Leuven researchers developed requires that a thief scan a target key fob with an RFID reader from just an inch or two away. And because the key-cloning technique targets the immobilizer rather than keyless entry systems, the thief still needs to somehow turn the ignition barrel—the cylinder you slot your mechanical key into."
So... I'm not getting too spun up by this. Just my US$0.02.
