There are new cars out that open the door and alow you to start the igition without inserting a key.

The "key" is a RF device that communicates with the car to tell it that you are OK to get in and drive. I imagine this is done with Bluetooth technology.

Does anyone know if this system is available yet in the aftermarket? It would be cool to combine this system with a pushbutton start.

 

uhhh thats not new.
its not bluetooth either.
it is an accessory that most car alram manuf. offer. I had it installed on my car about 3 years ago. I purchased it with my Clifford car alarm. There are bypass for turbo timers too. This way you can arm your alarm whule your motor is still running. welcome to the year 2004!

 

Call me paraniod, but couldn't the signal for these keyless ignitions be hacked and allow the car to easielly be driven away? I geuss on the same note I'm against onstar too since that allows them to track your car. Again call me paranoid, but I like my safety and privacy.

 

i believe it's possible with bluetooth, not too sure though, here's the site with all the bluetooth automotive products, there's like 20 of them http://www.bluetooth.com/products/pr...AT=ALL&CAT2=27

 

no, if someone does manage to replicate the signal for keyless start, without the key in the ignition there are still kills. Such as if the brake/ clutch pedal are depressed with out the key in the ignition, or rpm kill (if rpms reach up to 2700) the engine stalls, or a mercury switch that sences movement of the vechicle.

 

That isnt the same system he was asking about. Alot of the new high end cars like Mercedes dont have a key slot at all. You have a fob in your pocket, walk up to the car and the doors automatically unlock. You get in and the fob lets the car know who you are and enables the push button ignition. Basically, having this fob in your pocket is the replacement for putting a key in and turning.

Would be pretty cool to do something with bluetooth. Hop in the car with your cell in your pocket. Car recognizes your phone and you are set to go.

 

It's a proximity setup if I'm not mistaken. The FOB is not active until it is in proximity of the RF (or whatever) field that the car is projecting. The field will activate the FOB and will in turn send it's own signal which the car will authenticate. Unless you're right there with a probe, it's doubtful that someone will intercept the signal from the FOB.

It's the same principal as some card readers, only at a somewhat higher power.

As far as the kill without the key in the ignition, kinda pointless. If you're going to have to put a key in, what's the big deal to just turn it at that point?

 

I don't think it's that easy to bypass.

Besides, most of these cars are expensive and therefore if you don't have proper insurance for them u deserve to have it stolen....

I like this system.

Imagine a loved one that is being chased by a psychotic BATMAN and being able to run to the vehicle without fumbling for keys and risk being impaled.

 

now thats realy effin cool. Even cooler would be to have such an RF "Fob" implanted into yourself. That way your car would unlock and you could get in just by going up to it.

 

Dude do you drive naked or something? I'd be pretty happy to just keep a keycard in my wallet, I think most of us carry those on us all the time, especially while driving.

And if you got carjacked they'd kill you a pry the chip from your lifeless body ! THAT ROCKS !!!

Seriously most bluetooth devices have to be paired... and the auth code is 4 digits max... which for me isn't enough to just try some brute force... if my math class isn't failing me there are 9999^2 solutions... which is roughly 81000 numbers... at an ATM with 3-5 try's I'm okay with that, but in a parking lot with nothing but time... it'd maybe take someone 1/2 hour.... probhably less...

 

Those are all friggin cell phone accessories. I have never heard anyone using bluetooth for anything other than wireless cellphone accessories and such. Anything else would just be infrared type technologies.

 

Yeah, bluetooth is a bit too common nowadays for me to be willing to try it; too many people have 802.11b laptops, and I'm sure there are all kinds of hacker programs available by now. I'd be more comfortable with some sort of RF transmitter, less people have them. In the end though, if a thief wants your car, they'll get your car. If they really want it, they'll use a flatbed truck and tow it somewhere they can have time to open it nicely.

I'm considering installing a remote-start, and leaving the doors and steering-lock key-operated. It would help warm the car up earlier and easier, which would be great for those using it as a daily driver.

BTW DCrosby, I believe it would be 10^4= 6561 possible keys (10x10x10x10).

acually it would be easy to cycle throught that many numbers, if you had a device that could rapdily do it for you. You wouldn't even have to know what your doing, just buy the device.

 

With bluetooth you do need to pair the device, but that doesnt mean the 4 digit number is all the security you have. The device being paired with your cell or whatever would need also need to be put in a more so that it will accept pairing. For instance, if I try have my cell search for my laptop, it can find it but nothing will work at all unless the 4 digit number is again entered in the laptop. You would have to set the car in some mode that makes it acceptable to being paired. I cant just turn on the laptop, enter my 4 digit number, and voila, the laptop and phone think they are best buddies. That number is only part of the picture and I am quite certain there would not be any risk to using it in an automotive environment.

 

My mistake but 10x10x10x10 = 10000.... not 6561

 

Bluetooth Ignition
good luck if ur cellphone ran out of battery

 

Yes Tom, this is what I am referring to. I want one.

 

There are under skin chips available already... A company (stock symbol name ADSX) just chipped the entire Mexican head of government. This is a more advanced chip that will let anyone who knows the frequency ("What's the Frequency Kenneth?") locate these people if they are lost or stolen.

This would be even cooler. To have your car recognize you without a fob... And open the garage and house when you come home.

 

Oh, the chip is the size of a grain of rice, can be implanted anywhere, and cannot be easilly detected.

 

As for security... Just like most computer passwords, if too many wrong tries are attempted within a set timeframe, the system can 'disuser' you or shutdown entirely for ten minutes before it is ready at accept a signal again. This way, even if you do have a device that can cycle through all possible combinations. It won't be fast or easy.

Still, does anyone know of anything available?

 

Still none?
