What are the reasons why Porsche cannot recognize the car key?

[CarolineRose]

Porsche cannot recognize the car key due to signal interference, prolonged parking, expired communication protocol between the key and the vehicle, or insufficient vehicle battery power. Here are the relevant details: 1. Reasons: The vehicle cannot recognize the key because there is a signal interference source in the location. Even after entering, the key cannot be detected, and finally, the key must be directly placed near the start button. The failure of the smart key could be due to either a dead car battery or a dead key battery. Battery issue: The battery may be problematic, or leakage may have caused the power to drain prematurely. 2. Transmitter and receiver: The key chip cannot be read, or the transmitter or receiver may be faulty. It is recommended to try a spare key. If the spare key also doesn't work, you may need to reprogram the key.
