TSA

Can you imagine the uproar if people learned that airplanes could be
unlocked from a distance?


TSA could care less.


The TSA wants 2 locks on every plane. Considering how easy it is to steal
an
unlock code, just imagine how they would react to such a security hole!

It may not even be necessary for a bandit to ever actually know the code.

The odds of that are millions to one...about like your neighbor having
the same code for their garage door opener.

Actually, there are surprisingly few codes on any given frequency,
especially since each key fob uses three and sometimes four of the
available codes--for open/close/panic and typically trunk release. It is
actually a fraction of the codes available for a typical four tumbler key
lock for any given type of key blank--so you can probably think of a
transmitting frequency as being analogous to a style of key blank.


IIUC, a fob can have one frequency and over one million correlation codes.

Ours does have a rear view mirror!

Then again, we use ours to tow gliders from time to time, and the pilot
needs to keep an eye on what the glider's doing.

In a country with a lot of people, and a lot of cars, million to one
chances happen rather frequently. A few years ago my Dad was just
getting ready to drive off in his car when it locked and the alarm went
off - someone had just parked the same model of car nearby and locked it
with the remote. Both cars responded to the lock.

I use my plane for family transportation. So the wife and kids don't
see a lot of difference between running out to the plane to go to
Mexico vs. going out to the car. So when the family runs out ahead and
we have the car I hit the remote unlock. The other day my wife asked
why the plane doesn't have a remote unlock. When you think about it;
why not have the same ease-of-use items in the plane as the car.

You have a million people within 500 feet (the range of a fob/garage door
opened) of you at any one time?

They're LONG odds, not impossibility.

Further, "a few years ago" such devices had maybe 200 codes and no
preventive logic.

Now, the systems are far more sophisticated.

Not relevant.

Given trips to malls, the supermarket, etc. in metro areas, it wouldn't
take long to have been exposed to a million people within 500 feet.

Precisely the point; it isn't impossible, just unlikely.

True, making it even less likely but still not impossible.

Completely relevant - it's the basis of how the devices are designed and how
codes are arranged.

I highly doubt anyone ever seriously concidered the implications of being
within 500 feet of a million people -AT ANY ONE TIME- since it would
be physically impossible.

Not hardly.

The probability of someone having a matching device is dependent on
the number of exposures to others having such a device.

The probability of it happening within the next 10 seconds is extremely
low.

The probability of it happening within the next 10 years is a lot higher.

The only way to make the probability 0 is to never make more than one
device with a given set of characteristics.

Only having that number of people AT ONE TIME is relevant in that ONLY then
can they set off your device.
