P0513 code meaning
Incorrect Immobilizer Key
What P0513 means
The engine module receives a secret code from the immobiliser or body module (Chrysler SKIM/SKREEM/RF hub, Saab CIM); if it does not match the stored code, P0513 sets and starting is prevented – Saab cuts fuel and blocks the starter. The most common trigger is a replaced or reflashed engine module that was not taught to the immobiliser (FCA, Saab), less often handshake timing on FCA hybrids or a key not programmed. FCA lists it as invalid SKIM key. It is not emission-related; CARB does not require immobiliser monitoring, and no source documents a warning lamp.
P0513 at a glance
- Check engine lightUsually not
- Emissions testNot an emissions code
- Limp modeNot expected
- Repair difficultyHard
- Typical labor0.5 to 2 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P0513
- Engine does not start or stops after 1–2 s
- Immobiliser or security lamp flashes
- Starter does not crank (Saab)
Common causes of P0513
- Most likelyEngine module replaced or reflashed and not taught to the immobiliser
- PossibleKey or transponder not programmed or faulty
- PossibleImmobiliser, body or RF hub module replaced or faulty
- Less likelySoftware fault in the handshake
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0513 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 5 | Area: vehicle speed, idle control and auxiliary inputs. |
| 13 | The exact fault in that area. |
What to do next
- Note P0513 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P0513
What does P0513 mean?
P0513 means "Incorrect Immobilizer Key". The engine module receives a secret code from the immobiliser or body module (Chrysler SKIM/SKREEM/RF hub, Saab CIM); if it does not match the stored code, P0513 sets and starting is prevented – Saab cuts fuel and blocks the starter. It is a generic code, so it means the same on every make.
Is it safe to drive with P0513?
P0513 does not normally turn on the check engine light by itself. Watch for the symptoms above and have it checked soon.
Will P0513 fail an emissions test?
P0513 is not an emissions code, so on its own it usually does not fail an emissions test. Other stored codes or a lit check engine light still can.
How hard is P0513 to fix?
Difficulty: hard. A typical repair takes 0.5 to 2 hours of work. This is a job for a workshop.
Will P0513 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
