ELECTRONIC KEY NOT DETECTED RESTART ALLOWED
If the vehicle has the keyless access system, this message displays when the keyless access transmitter is not detected inside the vehicle while you are trying to turn the ignition off. The vehicle may be near a strong radio antenna signal causing the keyless access system to be jammed. If you have the keyless access transmitter with you, get out of the vehicle and lock the doors. If you do not have the keyless access transmitter with you, you will be able to start the vehicle again within five minutes, or after the vehicle's content theft-deterrent system is armed. See Starting the Engine for more information.
