Searching for the Serial Number on your 300
The only thing you'll need to get the code is your radio's serial number (not part number!).
On all Chrysler's, you can find it in one of these places:
- Directly on the radio screen (by using some combinations of buttons)
- On the radio body itself - you'll need to pull it out and write down serial (which is not so hard).
Search for something like: Serial, SN, S/N, Serial Num...
1. Viewing 300's S/N on the Display
Unfortunately, on Chrysler 300 radios the serial number is not shown on the screen.
In that case, you'll need to remove the radio unit and check the sticker on the side of the radio.
2. Find the S/N on the Radio Unit's Sticker
The serial number is usually printed on a label attached to the head unit.
Step 1: Turn off the vehicle.
Step 2: After that, take off the surrounding panel.
Step 3: Then unscrew the radio brackets.
Step 4: Carefully pull the radio forward partially (Be careful not to damage the cables that the unit is connected to).
Step 5: Look for the serial number on the side of the unit.
Step 6: Write down the full S/N carefully and come back here so that we can generate your code.
Important: Don't mix the Serial Number from the Part Number!

Common Chrysler 300 Radio Code Situations
Many drivers encounter security code prompts on their 300 after electrical work.
Below are the most typical situations when this can happen.
Battery Change Lock
When the battery is disconnected, the Chrysler 300 radio locks automatically.
This security feature is designed to prevent theft by disabling the radio after power loss.
Other Possibilities
- Installing a used head unit will require the original radio code.
- After an ECU or software reset, the radio may lock.
- A blown fuse can cause the Chrysler 300 radio to request a security code.
- Jump-starting the vehicle can reset the radio, requiring the unlock code.
Can I get a Free Chrysler 300 Radio Code?
Want free Chrysler 300 Radio Code? Actually, you may find it.
In few cases, your code may already be available in the vehicle itself or in the documentation.
Checking these sources can save you time and money before using an online lookup tool.
Below are the simplest places to look.
Look for it in the Car Itself
- In the vehicle handbook, often on a code card.
- Inside the glovebox, sometimes on a small card.
- In the boot compartment, on a radio label.
- In your service book from the previous owner.
- On the head unit itself, if it was removed before.
Can the Dealer Get It for You?
Dealerships can retrieve your radio code by checking the vehicle records in their system.
They typically require proof of ownership before sharing the security PIN.
This is the official way to restore access to the factory radio.
Downsides:
- Some imported or older radios may need extra verification.
- You may need to visit the dealer during business hours.
- The lookup is often not instant and may require waiting.
- Dealers frequently bill for the code (It may cost more than 100$).

Most radios display a "CODE", "ENTER CODE", or "----" message when they are locked.
You typically use the preset buttons to select each digit.
After entering the full code, the radio will restore normal operation.
Try not to make mistakes, because too many wrong attempts can temporarily lock the radio.
It will allow you a few incorrect tries before showing a SAFE message.
You can reset the lockout by keeping the ignition on for one hour or a set waiting period.
The Radio Code - What is It and Why It's Important?
When the radio is disconnected from power, it automatically locks and requires an anti-theft code to be entered before it can be operated.
A radio code (also known as an anti-theft code) is a built-in security system integrated into factory car stereos to prevent theft.
This system makes sure that a stolen radio becomes inoperable without the correct code.
Entering the correct code returns full audio and infotainment functionality.
