Nope. It uses a key in the keyhole near the rear license plate to open the back hatch, where you pull a release for the doors.

If the keyless entry dies, there is a keyhole in the rear center of the vette, right above the license plate.

The keys work by using RFID tags. It will rarely break unless you torture it somehow. They are powered by the car themselves when you approach. These tags identifiers can be unique into the millions.

It is possible to get a RFID reader and dup the signal, but I imagine you would have to be extremely close to someone before you actually got a good reading to duplicate.

Any modern remote unlocking system worth it's salt uses rotating codes, so that it does no good to steal the last code used. Let's hope this is the case here.

Well not really,

RFID's are passive devices. Their power comes from the car emmiting a RF frequency which causes the crystals in the keyring to oscilate. This is picked up by the reader.

Since RFID it is a fixed passive device requiring no power, it would be impossible to "Roll the codes"

It is possible the keyring is using some type of active system that emmits 24/7 proximity signals. But the power drain would likely be so great that it would kill the battery in a few weeks. But I'm hypothesizing based on my experience with signal processors. So I could be way off base here.

I'm sure there's some other technologies in there to make this system more secure, but I haven't figured it out completely yet.

Could a C6 be started, the driver/owner exit the car (while idling) and allow someone to drive it? If so I can see someone killing the engine (manual) on a test drive and unable to re-start it.

I know this sounds far fetched but I have done exatly this, started my car, let my wife take it for a spin and when she came back she mentioned she killed it a few times while she was trying to pull away from stop signs etc.

I bet Scissors knows. Let's ask him. Earlier in this thread he said the C6 keyless system used the same technology as the C5 and he is also the expert on the C5.

The C5 system uses rolling codes so that an intercepted and recorded unlock signal can not be used to unlock the vehicle.


Proof of this is that under certain circumstances the fobs will get out of synch and must be resynchronized (press lock and unlock while standing next to the car).

Then why don't you respond to the post that DigitalGriffin made concerning the design and operation of the RFID's. BTW, I noticed that you had to sneak over to XLRForum.com on July 22, 2004 and ask them how the pushbutton starter worked.

And Scissors also stated that the C6 used the same technology to operate the doors and allow the keyless system to function, which is the question at hand. Does it or doesn't it use the same technology? I'm just asking Scissors to give a definitive answer. Simple question. Are they the same or not and explain why they are the same or why they are different.

Someone else already did. No need to repeat the correct answer. That the FOBs are not RFID is self-evident at this point.

BTW, I noticed that you had to sneak over to XLRForum.com
Calling it "sneaking" doesn't make it so. If I were to sneak, I certainly wouldn't use the username "Scissors."

But you've never let logic get in the way of your infatuation with me.

on July 22, 2004 and ask them how the pushbutton stater worked.
Yes, in reponse to a thread on this forum on the same day. If you'd stalked me a bit more, you'd have seen that.

http://forums.corvetteforum.com/showthread.php?t=866951

Right there, clear as day, I reported at 7:06 a.m. on 21 July 2004 that "the engine will only shut off if you have the manual transmission in reverse," as per c4c5specialist.

On the 22nd I went back to read the thread again (part of my morning routine.) I saw that G35c6MT asked "...shouldnt the Start Button on the Auto C6 work like the XLR? How does it work in the XLR?" I then posted a question on the XLRForum at 7:34 a.m.: http://www.xlrforum.com/showthread.php?t=528

A minute later I post on CF that I would have an answer to the question.

But I guess you didn't want to tell the whole story because that wouldn't fit in with your attack fest, would it? Yet again today, you've been owned. Try getting your facts straight before you start attempting to slander me.
