How to resolve the P0513 fault code?

[DelJade]

P0513 fault code indicates an incorrect anti-theft key, meaning the anti-theft controller has detected an issue with the key. The function of the anti-theft control module is to ensure the car can only start when the dedicated key is present and matches with various components. If a problem occurs, it should be addressed promptly at a professional service center. Based on the fault system principle and an analysis of potential causes, the following components should be checked: 1. Check if the battery voltage is too low. 2. Verify if the key chip is faulty. 3. Inspect the anti-theft read coil for any faults. 4. Examine the anti-theft controller (IMMO) and its power supply circuit. 5. Check the engine control system.
