C6 access system faq.
How does the C6 entry system work?
The C6 allows up to four FOBs to be associated with a single vehicle. When someone pulls on the membrane switches hidden in the door pulls, the car sends a signal, to which the FOB sends a reply to authenticate with the car and allow the door to open. The same thing happens with the engine start button and trunk release.
Can't someone just drive off with the car if the fob is nearby in the owner's pocket?
No, the car is able to triangulate the position of the fob using several antennas hidden within the car. If the fob isn't in the driver's seat, the car won't start.
Will the car constantly lock and unlock as I walk around my house with the fob in my pocket? My older Corvette did this.
No. The fob and car only communicate when a button or switch is pressed, either on the car or on the fob. Unless you change the settings using the DIC or use the fob in a manual mode, the car is constantly locked except for a split second when you pull on the handle and it releases and then re-locks.
What is the range of the fob in automatic mode?
Approximately 1 meter (that's 3.3 feet).
What if my passenger also has one of the car's fobs?
Again, the car can tell where they are. It will use the fob in the driver's seat for starting the engine.
Well what if the driver has more than one fob?
The car chooses the fob with the lowest number. Of the four possible fobs, each one is assigned a different number (1, 2, 3, and 4.) So, obviously, the driver who takes the car out the most should have #1 and so on.
What if my fob fails? How do I get in or out?
The doors have manual releases near the floor. So if you're inside you can just pull one and get out (but also set off the alarm.) If an emergency crew is outside, they can break the window and pull the manual release (if an emergency crew is trying to get in, a broken window is the least of your worries.) Remember, the C5 was the same way--the doors were automatically locked while in motion, so emergency crews already had to do this. If you're outside and don't want to break your window
, you can just use your key to open the trunk and then pull the door release cable.
What about starting the engine with a failed fob?
Simply insert the fob in the receptacle within the glove box. This works for those cases (the majority) where a fob problem is a low battery or interference.
How long does the fob battery last?
Don't know, but the car gives you plenty of warning via the DIC when the fob battery is detected as being low.
Won't the C6 have lots of problems that the C5 did not because of this new system?
Not really. Except for the triangulation calculation, there's nothing really new about the C6's system. The C5 also used membrane switches. The C5 also used a batter-powered fob which had to communicate with the car. The C5 also had power door locks. The C6 just uses the same technologies that the C5 already used, but in a better, more convenient manner.
The door suddenly won't open or opens only sometimes. Why?
It's possible that the fob is encountering radio interference from something such as a SpeedPass™ transmitter. All radio devices have this problem at times. The radio spectrum is a very crowded place.

[QUOTE=Scissors]Well what if the driver has more than one fob.
The car chooses one. (A "master" fob.)
Great info Scissors.... good post...
Above... the car actually chooses the lowest number FOB.. so that would be #1 if you only have #1 and #2.....
if you have a #3 and #4 fob is doesnt recognize those for the memory settings option.... this is what the manual says anyway...

Maybe I'm a skeptic, but this FOB thing has me concerned. It sure sounds like a lot of opportunity for problems.
I mean, this is the company, and car, that brought us the column lock - for 7 straight years!

Also, mentioned was EM interference from carrying the FOB in a purse with a cell phone, for example. Lots of men would carry in pocket (maybe not on the Left Coast
) with a cell phone worn on belt. Potential problems there?

Wow, the exact same information I got from my inside sources----- The internet, Corvette Forum. Digital Corvettes, Corvette Action Center, and about a half dozen different auto magazines.
