Q1. Will this PCM fit my 2009 Chrysler 300 / Magnum 5.7L HEMI?

5. Yes. This is a genuine OEM PCM (engine/powertrain control module), part number 05150397AE, for the 2009 Chrysler 300 / Magnum with the 5.7L HEMI engine. To be sure, check that the number printed on your current PCM matches 05150397AE, or send us your VIN and we will confirm the exact fit before you order.

Q2. Is the Chrysler 300 / Magnum PCM plug-and-play, or do I have to program it?

1. It ships programmed to your VIN, so it installs plug-and-play — you unplug the old unit and plug the new one into the same location. Because Chrysler PCMs are linked to the Sentry Key (SKIM) anti-theft system, the PCM and keys must be relearned with a Chrysler-capable scan tool after installation (a dealer or locksmith can do this).

Q3. Why do you need my VIN to program the Chrysler 300 / Magnum PCM?

1. Your 17-digit VIN lets us load the correct factory calibration for your exact Chrysler 300 / Magnum before the unit ships. You provide it at checkout; if it is missing we contact you before shipping. Your VIN is on the driver's door-jamb sticker, at the base of the windshield on the driver's side, or on your vehicle registration and insurance card.

Q4. Will I need to re-register my keys or immobilizer after installing the PCM?

1. Yes, in most cases. Chrysler and Dodge PCMs are tied to the vehicle's Sentry Key (SKIM) anti-theft system, so after installation the PCM and keys must be relearned with a Chrysler-capable scan tool — a dealer or automotive locksmith can perform this. Contact our support team before ordering and we will tell you exactly what your vehicle needs.

Q5. Is this a genuine OEM part or an aftermarket copy?

1. It is a genuine OEM 05150397AE module that we remanufacture and test in-house — not an aftermarket clone. We restore the original factory unit and bench-test it with ASE-certified technicians before shipping, so it fits and functions like the factory part.

Q6. What are the symptoms of a bad Chrysler 300 / Magnum PCM?

1. Common symptoms include a no-start or hard-start condition, stalling, a check engine light with multiple or communication-related codes, rough running, poor fuel economy, and no communication with a scan tool. Have the codes read first to confirm the PCM is the cause before ordering; our team can help you interpret them.

Q7. Will replacing the PCM fix my check engine light or no-start?

1. If your diagnosis points to a failed PCM, installing this correctly programmed replacement should clear the module-related codes and resolve the no-start or warning light. If the underlying cause is a sensor, wiring, or mechanical fault, that problem must be repaired as well.

Q8. How long does it take to install the Chrysler 300 / Magnum PCM?

1. The physical swap usually takes about 15 to 40 minutes because the PCM ships pre-programmed. Allow a little extra time if your vehicle needs a key/immobilizer relearn or idle relearn afterward.

Q9. Do I need to send in my original PCM (core)?

1. Some orders require your original unit as a returnable core or for data transfer, while others do not. If a core is needed, you simply send in your old unit after you receive the replacement, and our team will confirm exactly what your part requires when you order.

Q10. What warranty comes with this PCM?

1. It includes a 6-month warranty plus lifetime phone support. The warranty is full for the first 3 weeks and prorated after that. If a covered unit fails, contact us and we will make it right under the warranty terms.

Q11. Is the PCM tested before shipping?

1. Yes. Every unit is bench-tested by ASE-certified technicians before it ships. We repair and test modules in-house, so the part you receive has been verified to function before it leaves us.

Q12. How much does the Chrysler 300 / Magnum PCM cost and what is included?

1. The current price is shown at the top of this product page. The PCM ships programmed to your vehicle, bench-tested, and ready to install (a Sentry Key/SKIM relearn is required after install), and includes a 6-month warranty with lifetime phone support.

Q13. How fast will the PCM ship?

1. Orders are programmed and shipped quickly. Once we have your VIN, your unit is programmed and shipped quickly, and you receive tracking as soon as it leaves us. Contact us if you need expedited delivery.

Q14. What is your return policy on this PCM?

1. We stand behind every unit. If you need to return a module, contact us first for a return authorization and instructions and we will guide you through the process. Please see our return policy for full details.

Q15. What if I get stuck during installation or the relearn?

1. Lifetime phone support is included with every unit. Our ASE-certified team can walk you through installation, any required relearns, and troubleshooting for as long as you own the part.
