Diagnostic Code P0513: Incorrect Immobilizer Key

One of the best things about modern vehicles is that they come equipped with an error code system. You can use a special device to read a vehicle's error code and learn what is wrong with it. This is what your mechanic will do when you bring your car into the shop. If you know what the code means and how to fix the issue, you can save yourself a little money by undertaking the issue yourself. You may not know what an OBD-II scanner error code P0513 problem means, but our guide will tell you everything you need to know.

The Meaning of the Error

So what does the code P0513 mean? This is an unusual error code because it might not indicate that anything is wrong with your vehicle. The car gives this error code when someone attempts to start the car without the right key. The very first thing you are probably thinking is that someone tried to steal your car. This very well may be the case, but there are a few other things that might have caused this error code.

Besides attempted theft, there may be an issue with the electrical system, or with the key itself. Many newer cars have a microprocessor in the key or key fob that communicates with the car. If you need a key fob to start the car, and you used the metal key without the fob nearby, it may have caused this error code to be sent. It is possible that the microprocessor is damaged or has run out of batteries. There also might be something wrong on your car’s side of things. The electronics that communicate with the key’s microprocessor might also be damaged.

Possible Symptoms

If you receive this error code, you should see the check engine light. The only other possible symptom is the car refusing to start. This is part of the security system. The entire car is shut down and will not start, which prevents anyone from stealing your car if they try to start it without the right key.

The Danger of Ignoring the Error

This is one of the most commonly ignored error codes since it does not necessarily indicate that something is wrong with the vehicle. If someone did try to steal your car, then there is a potential risk of someone trying again. If you are experiencing the inability to start your car, then you will obviously be unable to operate your vehicle. There is no danger associated with this, but it is very frustrating.

Try These Solutions

Want to learn how do I fix trouble code P0513? Follow these steps:

  • Reset the error code and your car should go back to normal. At this point, you can continue to use your car as you normally do. Keep an eye out for the error code appearing again or any problems starting the vehicle.
  • If someone did try to steal your car, you might want to consider improving your security system or parking your car somewhere safer. However, you should keep in mind that whoever tried to steal your car failed to do so, which may mean your security system is working just fine.
  • If the error code appears again, or you have trouble starting your car, it likely means there is an electrical problem, rather than a security problem. Start by visually inspecting the key and wires connected to the ignition. If you see any frayed wires or cracks on the key or key fob, it probably means something has been damaged. You should replace the broken parts.
  • If you see no sign of damage, you should assume the battery on the microprocessor is dead and either replace it or the whole fob.
