Understanding the 2023 Chrysler 300C Radio Code Retrieval Process
- Rather than relying on Chrysler dealership lookup or online threads you can generate the code online using the radio S/N.
- Identify your radio's serial. It is always present on the unit itself, and in some cases you can see it on the 300C's display.
- Type it into the generator above, and the system will identify the correct 2023 300C unlock code.
- After getting it, input it using 300C's radio buttons to release the blockade fully.
- The entire process takes just a short moment and requires minimal effort.
Radio Code Input Guide
Once you receive the correct unlock code based on the S/N, you can restore default functionality by entering it into the unit.
The code entry process depends on the head unit design, but most 2023 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.
Step-by-Step - The Correct Way to Enter It
To enter the code on the 2023 Chrysler 300C Uconnect 4C:
- Turn ignition to ON. Screen displays "ENTER CODE".
- Tap each digit of your 4-digit code on the touchscreen keypad.
- Radio auto-confirms after the 4th digit. No confirm button needed.
3 wrong attempts cause a 60-minute lockout. Keep ignition ON for the full wait. Switching off restarts the timer.
In-depth Entering Instructions for Chrysler 300C 2023
Once the unlock code has been retrieved for a 2023 Chrysler 300C Uconnect head unit, it can be entered directly at the dash - no scan tool or dealer visit required. With only 2,000 US / 200 Canada units built, getting it right first time matters.
Limited attempts. Mopar/Uconnect head units only accept three incorrect tries before the radio enters a WAIT state, so confirm every digit before pressing it.
Entering the code. Place the ignition in RUN/ACC so the radio powers up but the engine stays off. Wait for the display to show CODE, Please enter Anti-Theft Code, or a similar prompt. On the Uconnect 4C 8.4 (UAQ/UAS), tap the on-screen number pad and confirm with the OK/Enter touch button. If a 7-inch UAG is fitted instead, press the numbered preset buttons in sequence (preset 1 = first digit, preset 2 = second, etc.) - or use the on-screen keypad when the unit prompts for it.
If a wrong code was entered. If WAIT appears after incorrect attempts, leave the radio powered with the ignition in RUN for a continuous 30 minutes (the vehicle may be driven during this time) before trying the correct code again.
Can't Find Your Unit's Serial Number? Follow These Steps for Chrysler 300C 2023
The important thing to know is that factory radios use a unique serial number to identify each unitindividually.
The anti-theft system matches the code directly to this serial.
Unlike vehicle-specific data like VIN or registration information, it is not determined by the model or production year, so you'll be able to generate it even if you have a radio that you bought afterwards.
Depending on the maker and radio installed in your Chrysler 300C, the access method is different.
Here are the most reliable ways to find it.
2023 Chrysler 300C - The Final-Year Special Edition
The 2023 Chrysler 300C returned for one model year as a sendoff special edition, ending a two-year hiatus of the 300C nameplate (300C was absent from the 2021-2022 US lineup).The radio remains the LD-platform Uconnect 4 family.
- Uconnect 4C NAV (
UAQ) - 8.4-inch touchscreen with built-in GPS. Standard equipment on the 2023 300C special edition. Visual ID: 8.4-inch screen filling the dash opening with a 300c-logo Laguna leather interior surrounding it, dedicated NAV/Map tile on the home screen, on-board maps without a phone, plus Apple CarPlay and Android Auto. - Uconnect 4C (
UAS) - 8.4-inch non-NAV touchscreen. Not the factory fit on the 2023 300C special edition but possible after a service swap; same 8.4-inch glass without the Map/NAV tile. - Uconnect 4 (
UAG) - 7-inch non-NAV touchscreen. Factory fit on entry 300 trims rather than on the 300C special edition; listed for completeness if a smaller screen has been retrofitted.
Field test: 8.4-inch screen with a Map tile = UAQ (factory on the 2023 300C). 8.4-inch with no Map tile = UAS. Smaller 7-inch screen = UAG.
Using Hidden Radio Menus to Find the Serial
These are the steps you need to follow for 2023 Chrysler 300C:
The 2023 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. Navigate to: System Info → Radio Part Info → Serial Number.
Important Press the plastic bezel frame, not the touchscreen surface itself.
Find Your Serial Number on the Radio Display
The 2023 Chrysler 300C special edition - the final 300/300C ever built - keeps the Uconnect 4 line-up: 8.4-inch UAQ NAV (factory standard on 300C), 8.4-inch UAS non-NAV, and the smaller 7-inch UAG. The radio serial number can usually be read on screen via the hidden dealer/diagnostic menu, although the latest Uconnect software builds have restricted dealer-mode access on some cars.
Uconnect 4C 8.4 (UAQ - factory on 2023 300C). Switch the ignition to RUN/ACC and wait for the Uconnect interface to finish booting. Press and hold the driver-side temperature UP, the driver-side temperature DOWN, and the front DEFROST buttons together for roughly 5-10 seconds. If the climate-button shortcut does nothing on a software-updated unit, press and hold the bottom-left and bottom-right corners of the screen at the same time for about 5-10 seconds. Browse to the radio/system info section to view the 14-character serial number on screen, then photograph the screen so each character can be copied without typos.
If a 7-inch UAG has been fitted instead. Place the ignition in RUN/ACC and let the screen finish loading. Press and hold both temperature UP and temperature DOWN buttons together for around 5-10 seconds to enter the engineering menu. Open System Info / Target Main Data and read the serial number on screen, then snap a photo of the display before transcribing the digits.
Access it by Pulling Out the Unit
If the serial number cannot be accessed via display, use the removal method.
Most Chrysler 300C factory radios include a tag with the serial number printed on the housing.
The process:
- Disable power.
- Lift away surrounding panel pieces.
- Loosen screws holding the radio.
- Slide outward to inspect the label.
If Dealer Mode is unavailable on the 2023 Chrysler 300C 300C, remove the RA4 from the premium center stack.
- Carefully pry off the premium trim panel with a plastic trim tool — take care with the upscale trim.
- Remove the 4 Phillips mounting screws.
- Pull the unit forward to access the serial label on the side or back of the chassis.
Taking Out the Radio to View the S/N on the Tag
If dealer mode has been restricted on the 2023 Chrysler 300C special edition by a Uconnect software update, the printed chassis label remains the next reliable source. The Uconnect 4C head unit on the LD-platform 300C sits in a centre stack closely tied to the climate cluster, so methodical removal is important - especially given the limited 2,000-unit production run and the value of the 6.4L HEMI special edition.
Safety first. Turn the ignition off, take out the key, disconnect the negative battery terminal, and wait a few minutes before touching wiring. Never disturb the yellow airbag/SRS connectors and use plastic trim tools so nothing shorts or breaks.
Tools you will need. Plastic trim removal kit (a Mopar C-4755 trim stick or equivalent), Phillips and small Torx bit set, 7mm/10mm socket set, flashlight.
Removal overview. Pry the centre instrument panel bezel free with a plastic trim tool starting at the bottom edge and working up the sides; on the LD 300C the bezel carries the A/C-heater control and clock connectors, so keep finger pressure even and avoid scratching the special-edition trim. Unplug those harnesses at the rear of the bezel before laying it on a clean cloth. Remove the mounting fasteners (typically four screws, two upper and two lower) holding the radio cage to the support bracket. Slide the radio rearward and disconnect the antenna lead and the multi-pin power/data harness on the back.
Where the serial sits. The serial number is printed on a barcode/sticker label on the top or side of the radio chassis, next to the part number and supplier markings.
Tips. Photograph the label and double-check ambiguous characters such as 0/O, 1/I and B/8 before submitting the serial. Given the limited production run, having a professional installer remove the unit is a sensible choice if you are not comfortable working around airbag wiring or the integrated climate cluster.

Typical Serial Number Examples for 2023 300C
Year Chrysler 300C RA4 serial patterns:
T00AM– Harman RA4 Uconnect 4C (typical on the 300C)T00BE– Continental version
Serial is 14 alphanumeric characters. Part number (starts with P or 68) is on the same label — ignore it.
What a Valid Serial Number Looks Like
The factory radio on the 2023 Chrysler 300C special edition is the Uconnect 4C 8.4 NAV (UAQ). It uses the standard Mopar/Uconnect serial style, with the exact prefix depending on which supplier (Visteon, Continental, Harman or Panasonic) built the unit.
Uconnect 4C 8.4 (UAQ). Typically printed as a 14-character alphanumeric string on the chassis label. Commonly begins with T - frequent prefixes include T00AM, TM9 and TQ1 - or with A2C on Continental-built variants. The serial is usually a continuous run of letters and digits with no dashes or spaces.
If a UAS or UAG has been fitted as a replacement. The 8.4-inch UAS shares the prefix family with UAQ. The 7-inch UAG usually carries a Mopar/Harman or Panasonic-style serial on the chassis sticker; the label on the unit itself is the authoritative reference. Always copy the serial exactly as printed and avoid guessing characters that look unclear.
Fixing Common Code Entry Problems for 2023 300C
The radio label: serial = 14 alphanumeric chars starting with T00AM or T00BE. Part number starts with P or 68 — skip this.
The 300C Uconnect 4C uses touchscreen-only code entry. Tap each digit on the on-screen keypad. Confirms after the 4th digit. No physical buttons needed.
The 300C RA4 label has both serial and part number. Serial: 14 chars starting with T00AM or T00BE. Part number (skip): starts with P or 68.
Double-check carefully. Contact support for a free re-check if needed.
3 wrong entries lock the 300C RA4 for 60 minutes. Keep ignition in ON or ACC. Turning off restarts the timer.
If the 300C screen boots normally, the lock hasn't fired. Trigger the prompt: briefly disconnect the battery, reconnect, turn to ON.
What Caused the Radio to Lock?
The 2023 Chrysler 300C RA4 locks automatically after power is cut. The HEMI-spec 300C uses the same lock system as all Uconnect RA4 radios.
Typical cause: battery replacement or disconnect. Other causes:
- Blown fuse after electrical work
- Buying the 300C used without a code
- Battery disconnect during service
- Battery drained from storage
Code is derived from the radio serial number — not the VIN.
