Hi and thanks for using 2CarPros. Com. For some reason, the PCM is no longer recognizing the key fob. It means that the PCM has detected the presence of an immobilizer key that is does not recognize. If you try to start the engine, it will not start because the fuel and ignition systems are disabled by the PCM. I have attached a list of possible causes as well as a flow chart to help identify the problem.
SYMPTOM
P0513-INVALID SKIM KEY
WHEN MONITORED
Ignition on.
SET CONDITION
The PCM detects an invalid SKIM key.
POSSIBLE CAUSES
Incorrect VIN In PCM
Invalid SKREEM Key Not Present
No Communication With SKREEM
No VIN Programmed In The PCM
PCM
I hope they help.
Take care.
Joe
