You have a million people within 500 feet (the range of a fob/garage

They're LONG odds, not impossibility.

If there are 200 cars within range in a parking lot, with a million
codes, the odds of two cars having the same code are about 1 in 5000.
However, if you commute twice a day in different parking lots with 200
cars in range for work, there's about a 10% chance that you'll find
another car with the same code at least once a year.

This is still better than keys, which often have only a very small
number of "codes." In some cases there are only a dozen or so
different keys for all the cars of a specific model or even a specific
group of models. On one occasion, after locking myself out of a
rental car, I was able to open the door with a key for our own car,
and the only thing the two cars had in common was the manufacturer.
On another occasion, I got into a car in the parking lot that matched
my key, paint job, etc., only to discover that it wasn't mine.

Anyway, you need a lot more than one million different codes to be
secure.


You don;t know how it works, fukkwit.
