radio connection between the vehicle and the
key.
The distance to the door handle from which
you wish to lock or unlock the vehicle must
not be greater than 1 m.
When starting the engine and whilst driving,
KEYLESS GO also checks whether a valid key
is in the vehicle by periodically establishing
radio contact. X
