The P0513 diagnostic code comes up when there’s an issue with your immobilizer key. Immobilizer is a term used to describe a vehicle’s anti-theft system, so this issue indicates that a problem exists within the anti-theft process.
If the system doesn’t read the electronic key as present when starting the car, then the powertrain control module will store this code in the memory.
What Does Code P0513 Mean?
Diagnostic trouble code (DTC) P0513 stands for “Incorrect Immobilizer Key.”
The immobilizer system works using radio frequency identification (RFID). The transponder or smart key has a microchip, which enables it to connect to the powertrain control module (PCM). Inserting the key into the key cylinder will instantly trigger the immobilizer system to operate.
P0513 is logged when the PCM can’t recognize the immobilizer key inserted in the cylinder.
The PCM usually searches for a cryptographic signature from the key fob. The vehicle will only start (activate fuel injection and ignition sequences) if the key fob is valid. If it’s not, the PCM will trigger the P0513 code. Some systems will start and die, and you’ll notice a flashing immobilizer light.
Note that P0513 is related to passive anti-theft. You can learn more about it in our discussion about immobilizer systems.
