How Serial Numbers Work and Where to Find Them on 2024 Chrysler 300C Radios
The first step is finding the radio serial number.
Many drivers assume the code depends on the Chrysler model or year, but in reality, the unlock process depends on the unique radio unit's serial number.
The serial is the key used to calculate the correct unlock code.
This is even better, because if you have an aftermarket radio, the VIN or other Chrysler-specific data wouldn't be of much use.
Depending on the radio version used, you can retrieve the serial directly from the screen or by checking the label on the radio chassis.
Display-Based Serial Number Retrieval
The method for 2024 Chrysler 300C is this:
The 2024 Chrysler 300C — the HEMI V8 top-trim final-generation 300 — features the Uconnect 4C (RA4). Press the bottom-left and bottom-right corners of the physical bezel frame simultaneously for 5 seconds (ignition ACC or ON) to open Dealer Mode. Go to: System Info → Radio Part Info → Serial Number.
Important Press the plastic bezel frame, not the touchscreen surface itself.
Pulling Out the Unit to Access the S/N on the Tag
If the serial number cannot be accessed via display, use the hardware method.
Most Chrysler 300C factory radios include a sticker with the serial number printed on the chassis.
The process:
- Ensure the ignition is off.
- Carefully remove surrounding dashboard trim.
- Loosen screws holding the radio.
- Pull forward to inspect the label.
If Dealer Mode is unavailable on the 2024 Chrysler 300C 300C, remove the RA4 from the premium center stack.
- Remove the center bezel with a plastic trim tool — avoid scratching the upscale trim.
- Remove the four Torx T20 mounting screws.
- Slide the unit out to read the serial label on the side or back of the chassis.

How to Enter the Radio Code
After generating the correct unlock code based on the serial number, you can restore normal functionality by entering it into the unit.
The code entry process depends on the head unit design, but most 2024 300C systems follow a similar structure using preset buttons, touch controls, or rotary knobs - depending on if it's a factory or an aftermarket unit.
You will typically see ENTER CODE displayed on screen.
