Smart key not programmed

When a smart key fails to program correctly, it indicates that the vehicle's recognition system is unable to synchronize the transponder signal with the ECU. This can occur due to a damaged key, a dead internal battery, electronic interference, or a malfunction in the immobilizer module. As a result, the vehicle does not recognize the key and locks the ignition. A specialized automotive locksmith can reprogram the key, restore communication with the ECU, or generate a new, fully functional key if the original cannot be recovered.
