KEYS
KEY FOBS
Your vehicle is equipped with a key fob which supports
Passive Entry, Remote Keyless Entry (RKE), Keyless
Enter ‘n Go™ (if equipped), Remote Start (if equipped),
and Panic button operation. The key fob allows you to lock
or unlock the doors and liftgate from distances up to
approximately 66 ft (20 m). In some conditions, this
distance can be reduced or increased. The key fob does
not need to be pointed at the vehicle to activate the
system. The key fob also contains an emergency key,
which is stored in the rear of the key fob.
NOTE:
The key fob’s wireless signal may be blocked if the key
fob is located next to a metallic object, mobile phone,
laptop, wireless charging pad, or other electronic
device. This may result in poor performance.
 If the key fob’s battery is near depletion, the key fob
performance can be reduced.
 With the ignition on and the vehicle moving at 2 mph
(4 km/h), all RKE commands are disabled.
