Also, this code also means that the PCM has detected the presence of an immobilizer key that it does not recognise. Which, of course, refers to the ignition key. If the ignition cylinder is turned on and the engine has cranked (not started) and the PCM fails to detect any immobilizer key, the P0513 is stored. 

To authenticate the identity of the vehicle’ Immobilizer key there are three different elements in total that work together as a means. These comprise of the powertrain interface module, PIM, the body control module, BCM and the powertrain control module (PCM). if the key identity does not match the programmed identity, then a trouble code is stored and the malfunction indicator light is illuminated.

What causes this problem with Incorrect Immobilizer Key?

• Defective Immobilizer Key.
• Bad electricity connection for Immobilizer Circuit Components.
• A fault in the Immobilizer Key Antenna.
• Damaged Immobilizer Control Unit.

• The Immobilizer key should be restored.
• The Ignition cylinder should be tested if the Immobilizer key is not the problem.
• The Ignition key should be replaced if the required.
• The Boxed end wrench should or Ratchet sets should be visually inspected and replaced if needed.

• The PCM, BCM and PIM collaborate together as essential parts of the vehicle security system.
• The security data received from these modules is then authenticated by the theft deterrent system to avoid unauthorized vehicle operation.
• The system activates following this procedure: the doors are unlocked using the hand held remote key fob or the key, the data is transmitted.
• Then the data is read by the BCM, that further ensures the use of the correct key.
• A same action can be noted occurring while the ignition key is placed in the cylinder and turned.
• Next, the BCM tests the signals sent from the key and ensures that it matches the vehicle.
• Once the key has been verified, the identities of BCM, PIM and PCM are also verified.
• If there is any kind of a disruption in the process and a component is left unidentified by the theft deterrent system, the vehicle may fail to start and may end up storing up the code again.
• Many tools will be instrumental in accurately diagnosing the code.
• a n appropriate OBD-II scanner (or code reader) and a digital volt/ohmmeter would prove extremely helpful while performing the diagnosis.
• A visual inspection of all the wirings and connectors is essential.
• All damaged, disconnected or burnt wirings, connectors and components should be restored or repaired.
• Finally, a retest should be performed after all the amendments are carried out to ensure correctness and accuracy. If the entire system including the wirings, connectors and components (fuses too) work in normal conditions, the scanner should be connected to the diagnostic connector to record all the freeze frame data and stored codes.

Common Mistakes When Diagnosing the P0513 Code

Anxious? Don’t want to take a chance while diagnosing the Error code P0513? Here are a few common mistakes that should be avoided while diagnosing the code:

Many a times, the technician might end up overlooking the fact that the error is caused by a problem within the Immobilizer key. Alternately, they might look at the ignition cylinder since the vehicle has trouble in starting or would not start at all. They might actually end up replacing the ignition cylinder to clear the code and later find out about the other problem. Mostly, it is always that the problem has to do with the key.
