Keyless Go antenna, function - GF82.62-P-4100-04RS

The Keyless-Go antennas (A2/31, A2/35, A2/36, A2/38, A2/40 and A2/60) are actuated by the Keyless Go control unit (N69/5). Their electromagnetic fields induce the transmitter key (A8/1) to send its authorization code over two-way radio to the right antenna amplifier module (A2/65).

Keyless-Go antennas (A2/35, A2/36 and A2/60) are used to determine whether the transmitter key (A8/1) is located in the interior compartment.

Keyless-Go antennas (A2/31, A2/38 and A2/40) are used to determine whether the transmitter key (A8/1) is located outside the interior compartment.

The body panel attenuates the fields of the Keyless-Go antennas (A2/31, A2/35, A2/36, A2/38, A2/40 and A2/60), this in turn defines the range. The range outside the vehicle is approx.

1 to 1.5 m.

This defined range limitation enables the Keyless Go control unit (N69/5) to decide, whether the transmitter key (A8/1) is within or outside the vehicle.
