Where to Search for the Serial Number on your 300C
To get the correct unlock code, you first need the serial number from the radio.
Depending on your 300C, you can see it on the screen or find it on the radio unit itself.
Common abbreviations are S/N, SN, Serial, Serial Num., Serial Number...
These are the most common ways to find it:
1. View the Serial Number on Chrysler 300C's Display
Unfortunately, on Chrysler 300C 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. Locating the Serial on the Radio Unit
To find the serial number, you'll need to take out the radio unit out.
- Start by turning off the ignition and taking off the dashboard bezel.
- Next, release the clips and slide the radio out to check the label on the side of the radio. Be careful not to damage the cables that the unit is connected to.
- Write down full serial number precisely and come back to our website.
- Know that serial number and part number are not the same. You will find both on the sticker, and you only need for the first one.

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 confirm the entry.
If you fail multiple times, you may cause the 300C's head unit to block further attempts.
When this happens, the screen can display messages like "CODE ERR", "ERROR", or a blank screen.
To unlock the system, you usually need to keep the ignition on for a waiting period or up to an hour before trying again.
What is a Radio Code and Why is it Important?
A radio code, also known as an anti-theft code is a unique numeric unlock key that reactivates your car audio system after it has been locked.
This security code is triggered when the radio is disconnected from power.
Automakers include this feature to protect factory stereos from theft.
If power is interrupted, the radio disables itself and asks for the CODE before it can function normally.
Once the valid numbers combination is entered, the stereo is fully reactivated.
