Issue

A customer may complain that the "Smart key not found" message is displayed intermittently in the IPC (Instrument Pack message center). The message may appear when closing doors or pressing the start button, and will result in a non-start condition..

Also if the driver's door is opened / closed with the engine running a second key scan will be initiated. If the key has been moved to a position in the vehicle where it is not recognized by the RFA the "Smart key not found" message will be displayed.

Cause

RF signal tuning inside the vehicle, when the Smart Key is placed in a particular location / orientation / position e.g. On Evoque this could happen if the key is in the center console cupholder area.

On Range Rover Sport, Discovery4/LR4 & Range Rover if the key is placed on the center console by the clock or HVAC (Heating Ventilation & Air Conditioning) control module.

CONTENT

Action

When the "Smart Key Not Found" message is displayed, make a note (if possible) of the exact location / orientation / position of the Smart Key when the message was displayed. Remove it from that location and place the Smart Key next to the IAU (Immobilizer Antenna Unit). Which is located on lower drivers side fascia for all models except Evoque where it is under the steering column. Press the start button once the "Smart Key Not Found" message has cleared from the IPC.

NOTE: If the user does not allow the message to clear, the IAU will not perform a Smart Key Scan and the vehicle will not start.

After confirming that all Smart Keys are functioning, advise the customer that JLR is aware of the concern, and is working towards a software fix that will be released in the near future. In the interim if the "Smart key not found" message is displayed please move the key to another location within the vehicle.

Under no circumstances should Smart Keys be replaced for intermittent "Smart key not found" messages being displayed, unless after following the above process the key will not function as required.
