  1. areas covered by the door antennas
  2. area covered by the tailgate antenna
  3. areas covered by the interior antennas
  4. area covered by two antennas, which may not be covered if the phase of one of the two antennas is reversed.
Note: If an antenna is short-circuited to ground, the coverage area may be doubled.

If an interior antenna is short-circuited to earth, it may cover the exterior antennas (risk that locking/unlocking is not possible, but starting is possible, with the card outside the vehicle).

If an exterior antenna is short-circuited to earth, the vehicle can only be locked/unlocked when the card is located approximately 2 m or more from the vehicle.
