“Key Not Detected” error on my vehicle
Fix the “Key Not Detected” error by checking the transponder and communication with the immobilizer so that your vehicle recognizes the key correctly.

The message “Key Not Detected” appears when the vehicle's system fails to identify the signal from the smart key or transponder . This fault can occur for several reasons: a weak battery in the key, a damaged transponder, problems with the vehicle's receiver antennas, immobilizer malfunctions, or reprogramming caused by a battery change or an electrical surge.
When this happens, both remote unlocking and engine ignition stop working, leaving the vehicle completely inoperable.
