Remote Keyless Entry (RKE)
System Operation
The vehicle's doors can be locked and unlocked, and
the trunk can be unlatched from about 3 feet (1 m) up to
60 feet (18 m) away with the Remote Keyless Entry
(RKE) transmitter.
If your vehicle has the remote start feature you can also
start your vehicle with the RKE transmitter. Your RKE
transmitter, with the remote start button, provides
an increased range of 195 feet (60 m) away. However,
the range may be less while the vehicle is running.
As a result, you may need to be closer to your vehicle
to turn it off than you were to turn it on.
There are other conditions which can affect the
performance of the transmitter. See Remote Keyless
Entry (RKE) System on page 2-4.
