Anyone else hear of their tC being broken into with no forced entry. I have had my radio and GPS stolen last night. Since I know it was locked the police are saying some one has another remote that can open my car.

This sucks... my car is no longer secure.
Any suggestions?

 

I'd call the dealer and see if they can reprogram your remotes to a different code. I have no idea if it can be done to our cars, but it would at least be worth the call.

 

Maybe they used a tennis ball?

 

if i remember right - you can make, or get offline remotes that will open up doors..like that...car thiefs use them more and more nowadyas....they have a broad range of feqs they send out till it opens up a car or something like that...I saw it on tv or something a while back

 

sure do

 

Yeah its very rare that something like that would happen. I remember one time I was at a BMW dealership here in So Cal and my cousins keyless entry unlocked another beamer on the lot. (he owns a bmw also) He notified the dealer and they changed both of the codes of the cars.

 

It's not that hard to make something that will cycle through a set list of codes in order to open a car or say a garage door. I think now though, garage doors have millions of possible codes, where in the past, it was only a few thousand.

 

Them taillights are bad a**. Where did you get them?

 

These are rather rare, and the people interested in these probably don't go after tC's.

The technology to crack a keyfobs code is tough, not impossible, but tough.

 

not that i doubt that it's possible, likely, or currently in use, I'd like to see some documentation on the brute force code gen attack that is being mentioned here. If anyone has any decent links, post them or PM them to me please.

 

I know that clifford had an alarm in the 80's that used a billion digit code. To hack that one at the time, with the most advanced scanner trying every possible code would have taken about 50 years. And that was 20 years ago, so I'd imagine that the codes for the keyless entry and all have gotten a little more advanced and sophisiticated in 20 years. But who knows.

 

Okay, I've found information on the algorithm used in our cars. having the dealer change the code will not help. The remote sends a different code to the control unit each time it is used. This helps prevent what is known as a 'replay attack' where the signal is intercepted, and repeated to the control unit.

there is a process known as a 'slide-algebraic attack' that the algorithm is vulnerable to, in which the algo is typically cracked by brute force in about two weeks.

this means that to perform this attack, the car would have to be targeted. followed, maybe. more likely, a magnetic recorder would be placed under the vehicle.

fwiw, this process was used on an episode of NUMB3RS...but the info I found was from a much less fictional source.

 

So the code cracking in this instance is an analysis or a copy of the key code rotation cycle? I miss the good old days when cryptography was just stick figures of dancing people.

 

thats what the pm button is for...


now back on topic.

 

tc shouldnt be a target for car theives but the equipment in it is a great target i want a security system that shoots fire.

 

it's an analysis that is fairly involved.

 

Is it possible they are getting in with an actual key and not a remote? With my last car, they found that the person who stole my stereo and school books got my VIN # from my windshield, took it to a Honda dealership, and they gave him a key for it. The police said it was getting more common and dealerships are not checking for proper registration info.

My suggestion would be to get an alarm system.

 

Just for curiosity, where did you get this source for the slide attack?

Yeah, I have heard of this happening too, its probably the more likely scenario.

 

source? google it ;)

+1 on the VinKey. more likely.

 

Maybe it was UNLOCKED and when they finished, they locked the car to try to confuse you...
