Physical barriers between the key and the vehicle may adversely affect the range or obstruct the signal completely.
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 tailgate.
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.
