Corvette V8-6.2L (2008)
Both the vehicle architecture (fiberglass body) and the environment surrounding the vehicle may contribute to some variability in system performance. A
common possible concern is when the sleep command extends just slightly outside the vehicles interior. Under this scenario, the door may not open when
a fob is very close to the door handle switch (refer to the graphic). Moving the fob away from the handle switch will restore normal system operation.

Vehicle Starting
Again, there are several antennas in the vehicle that detect the fob's presence in the vehicles interior. These antennas are turned ON by relays in the
controlling module. A slight clicking noise or chatter may be heard when the antennas are turned on. This is a normal and expected system function.
When the start button is pushed, the antennas are turned ON so that they may detect a fob on the inside of the vehicle. If a valid fob is found, the vehicle
is allowed to start. The starting range may extend slightly outside of the vehicle, but not more than 10-12 inches (25-30 cm).
Refer to the section on "Interference" below for other issues that may cause problems with vehicle starting.
Interference
The Keyless Access System relies on radio frequency (RF) signals to allow passive entry and starting. It is possible that other devices may interfere with
the RF signals. These types of devices include (but are not limited to) cell phone chargers, two-way radios, power inverters, computers, etc. The most
common type of interference is from cell phone chargers (regardless of whether the cell phone is plugged into it or not). High RF traffic areas, such as
gas stations which use pay-at-the-pump RF transponders, may also cause interference that could lead to a customer perceived malfunction.
The Keyless Access system operates by using two separate radio frequencies.
Important:
GM's devices conform to all FCC and Industry Canada regulations. Not all radiating devices that are sold publicly conform to the same regulations
and can cause interference with the system's operation.
The way to determine if devices inside your vehicle are interfering with the Keyless Access System is to hold the fob directly next to the suspect device
and press the start button. If the DIC displays "No Fob Detected" this device is likely causing a disruption to the system. Usually, keeping the fob farther
away from the device will correct the problem. Changing parts in the system (fob/receiver) will normally not correct this issue. The source of the
interference must be eliminated.
Occasionally, it is possible to be in an area where external interference is present. For instance, parking directly under a radio transmitter tower may
cause issues with entry or starting. The vehicle is equipped with backups and safeguards to assist you in entry and starting.
