P0513 code definition

When the P0513 trouble code appears, it indicates that the powertrain control module has found an issue with the immobilizer key ID.

What the P0513 code means

There are three different elements that work together as a means to authenticate the identity of the vehicle immobilizer key. These include the powertrain interface module, or PIM, the body control module, or BCM, and the powertrain control module, or PCM. If the key identity is not the same as the programmed identity, then a trouble code will be stored and the malfunction indicator light could come on.

What causes the P0513 code?

The following are some of the most common causes of the P0513 code.

  • Faulty immobilizer key
  • Poor electrical connection for immobilizer circuit components
  • Faulty immobilizer key antenna
  • Faulty immobilizer control unit

What are the symptoms of the P0513 code?

Those who have the P0513 trouble code stored on their vehicle will often find that their Check Engine Light is lit, as well as their security Light. In addition, the engine may be more difficult to start and in severe cases it may not start at all.

How does a mechanic diagnose the P0513 code?

Diagnosis of the P0513 code starts with the mechanic connecting his or her scanning device to the vehicle’s onboard computer. They will check for the stored trouble codes and will then reset the code. After resetting the code, they will want to drive the vehicle to see if the code returns. If the code does return, then they know they’re dealing with a real problem rather than a false code.

They can then start looking into the actual issues that would cause the code to appear, such as the faulty immobilizer key antenna or faulty immobilizer key. Mechanics should start at the simplest potential issues first and then work their way up.

Common mistakes when diagnosing the P0513 code

Sometimes, a mechanic may overlook the fact that the error is actually caused by a problem with the immobilizer key. Instead, they may look at the ignition cylinder since the vehicle has trouble starting or will not start at all. They may actually replace the ignition cylinder and find out that the code remains and that they have another problem. In most cases, the problem has to do with the key.

How serious is the P0513 code?

The P0513 code can actually be quite serious. In some cases, the only problem might be an illuminated Check Engine Light or a service engine soon light that comes on. However, most of the time, the problems are a bit more severe. People may have issues when it comes to starting their vehicle, and in some cases it will not start at all. Having a vehicle that doesn’t start means not getting to and from work, not being able pick up the kids, not getting groceries, and more. Therefore, it is very important to have this issue taken care of as quickly as possible.

What repairs can fix the P0513 code?

The following are some of the most common types of repairs and fixes for the P0513 code.

  • Scan the system, reset the codes, and then run the vehicle to see if the codes return
  • Replace the immobilizer key
  • Test the ignition cylinder if the immobilizer key is not the problem
  • Replace the ignition cylinder as needed

Additional comments for consideration regarding the P0513 code

The P0513 trouble code has the potential to cause some serious problems for those who are driving their vehicles. If they don’t start or they are hard to start, it is a massive issue that needs to be repaired as quickly as possible. This code, as well as any other code stored in the vehicle, should be looked at by a mechanic and repaired.
