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 65 feet (20 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.
