When using the key buttons
The key's functions that are controlled by the buttons have a range of about 20 meters (65 feet) from the vehicle.
If the vehicle's locks do not react, move closer and try again.
Keyless* use
For keyless operation to be possible, the key must be within a distance of about 1 to 1.5 meters (3 to 5 feet) from the vehicle's doors or trunk lid.
Note
The functions of the key can be disrupted by ambient radio waves, buildings, topographical conditions, etc. The vehicle can always be locked/unlocked using the key blade.
