Vulnerability In Car Keyless Entry Systems Allows Anyone To Open And Steal Your Car

Excerpt: According to the lock specialists at Ford, each keyless-entry transmitter has a transmitter identification code (TIC) that is programmed and, therefore, linked to the vehicle. But even if thieves manage to mimic the TIC, the unlocking/locking process is even more complicated.

I've heard that. Here's my question: I buy a car and get two fobs. I lock the car and take a bus to the other side of town. The wife comes home from a business trip far away and, having had her keys with her (read - far out of range of either the car or my fob) pushes the unlock button and the car opens. How does the car open since her fob cannot know the code used the last time?

Besides it is geared so low, it tops at 45

Heh.
My college ride was a '46 Willys CJ2A, flat head four, 5.38 rear end, two speed transfer case, the whole headache.

Was a little faster than 45, but my jeep club was usually annoyed when I went along on mountain rides as they liked to run together on the highway to and from... and they had to slow to my maxed out, screaming speed of barely around 55.

:) It was great!

I have the perfected the best anti-theft system by driving a piece of crap no self-respecting thief would want to be caught dead in.

Each fob has its own ID. It's the next code in the sequence for that fob.

Bring back “Hanging for Horse Thieves”.

The issue should not be how it it possible to defeat a locking or security system. The issue is:

Thou Shall NOT Steal!

Same for Identity Thieves... in fact, more-so.

I would suspect that a sequence is used for each independent fob.

The scary thing about these fobs is that the fob batteries only last two years. I was lucky that my battery died while the car was at home rather than on a trip.

See Post #24 in this thread. That should answer your question.
