Unlock Your 2020 Chrysler 300C Radio in Minutes - How It Works

Car radios use security codes dependent on the radio unit itself rather than the model or production year.

  • The generator identifies your Chrysler radio via serial-based verification.
  • Once the serial number is submitted, the system identifies the radio family and retrieves the corresponding code.
  • Use the code to unlock the radio immediately.
  • This approach saves time compared to traditional methods for 2020 Chrysler 300C.

Can't Locate Your Radio Serial Number? Follow The Steps Below for Chrysler 300C 2020

The useful thing to know is that factory radios use a specific serial number to identify each unit.

The security system matches the code directly to the serial.

Different from vehicle-specific data like VIN or registration info, it is not determined by the model or production year, so you'll be able to retrieve it even if you have an aftermarket radio.

Depending on the maker and radio installed in your Chrysler 300C, the access method is different.

These are the best ways to locate it.

2020 Chrysler 300C - Factory Radio Lineup

The 2020 Chrysler 300C continues as the flagship trim of the LD-platform 300 and keeps the Uconnect 4 family. Three head units exist across the broader 300 lineup, but on the 300C trim the 8.4-inch UAQ NAV is the standard fit.

  1. Uconnect 4C NAV (UAQ) - 8.4-inch touchscreen with built-in GPS. Standard on the 2020 300C. Visual ID: 8.4-inch screen filling the dash opening, dedicated NAV/Map tile on the home screen, on-board maps without a phone, plus Apple CarPlay and Android Auto.
  2. Uconnect 4C (UAS) - 8.4-inch non-NAV touchscreen. Not standard on 300C but possible after a service swap. Same 8.4-inch glass as UAQ, but no Map/NAV tile and no on-board maps.
  3. Uconnect 4 (UAG) - 7-inch non-NAV touchscreen. Factory equipment on entry trims rather than 300C, listed for completeness in case a smaller screen has been retrofitted.

Quick test: 8.4-inch screen with a Map tile = UAQ (factory on 300C). 8.4-inch with no Map tile = UAS. Smaller 7-inch screen = UAG.

Display-Based Serial Number Retrieval

These are the steps you need to follow for 2020 Chrysler 300C:

The 2020 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.

Quick Method: Find the Serial Number on the Screen

The 2020 Chrysler 300C continues with Uconnect 4C 8.4 hardware - the UAQ NAV unit as factory standard. The radio serial number can normally be read on screen through a hidden dealer/diagnostic menu, although some 2020 builds had dealer mode tightened by a software update.

Uconnect 4C 8.4 (UAQ - factory standard on 300C)

  1. Switch the ignition to RUN/ACC and wait for the Uconnect interface to finish booting.
  2. Press and hold the driver-side temperature UP, the driver-side temperature DOWN, and the front DEFROST buttons together for roughly 5-10 seconds.
  3. If the climate-button method does nothing, press and hold the bottom-left and bottom-right corners of the screen at the same time for about 5-10 seconds.
  4. Browse to the radio/system info section to read the 14-character serial number on screen.
  5. Photograph the screen so each character can be transcribed without typos.

If a UAG 7-inch is fitted instead

  1. Place the ignition in RUN/ACC and let the screen finish loading.
  2. Press and hold both temperature UP and temperature DOWN buttons together for around 5-10 seconds to enter the engineering menu.
  3. Open System Info / Target Main Data to view the serial number on screen.
  4. Snap a photo of the display so the digits can be copied accurately.

Pulling Out the Unit to View the S/N on the Tag

If the serial number cannot be accessed on-screen, use the removal method.

Most Chrysler 300C original radios include a tag with the serial number printed on the chassis.

Basic process:

  • Shut down the car.
  • Lift away surrounding dashboard trim.
  • Loosen screws holding the radio.
  • Pull forward to inspect the label.

If Dealer Mode is unavailable on the 2020 Chrysler 300C 300C, remove the RA4 from the luxury cabin center console.

  1. Remove the center bezel with a plastic trim tool — take care with the upscale trim.
  2. Remove the 4 Torx T20 mounting screws.
  3. Slide the unit forward to access the serial label on the side or back of the chassis.

View Serial by Pulling Out the Radio Unit

If dealer mode has been restricted on a 2020 Chrysler 300C by a Uconnect software update, the printed chassis label remains the next reliable source. The Uconnect 4C head unit on the LD-platform 300C is closely integrated with the climate cluster, so a careful, methodical removal is important.

  1. Safety first: turn the ignition off, remove 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.
  2. 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.
  3. Pry the centre instrument panel bezel free with a plastic trim tool starting at the lower edge and working up the sides; on the LD 300C this bezel also carries the A/C-heater control and clock connectors, so keep pressure even.
  4. Unplug those climate and clock connectors at the rear of the bezel, then set the trim aside on a clean cloth.
  5. Remove the mounting fasteners (typically four screws, two upper and two lower) holding the radio cage to the dash support bracket.
  6. Slide the radio rearward and disconnect the antenna lead and the multi-pin power/data harness on the back.
  7. The serial number sits on a printed barcode/sticker label on the top or side of the radio chassis, next to the part number and supplier markings.
  8. Photograph the label and double-check ambiguous characters such as 0/O, 1/I and B/8 before submitting the serial. If you are not comfortable working around airbag wiring or the integrated climate cluster, have a professional installer remove the unit for you.

How Serial Numbers Usually Look on These 300C Radios

Year Chrysler 300C RA4 serial formats:

  • 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 — skip it.

Standard Serial Number Patterns on This Radio

The factory radio on the 2020 Chrysler 300C 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)

  1. Typically printed as a 14-character alphanumeric string on the chassis label.
  2. Commonly begins with T - frequent prefixes include T00AM, TM9 and TQ1 - or with A2C on Continental-built variants.
  3. Usually a continuous run of letters and digits with no dashes or spaces.

If a UAS or UAG has been fitted as a replacement

  1. The 8.4-inch UAS shares the prefix family with UAQ.
  2. The 7-inch UAG usually carries a Mopar/Harman or Panasonic-style serial on the chassis sticker - the printed label on the unit itself is the authoritative reference.
  3. Always copy the serial exactly as printed and avoid guessing characters that look unclear.

Got the Code? Here's How to Enter It

Now that you've generated 2020 Chrysler 300C unlock code from the serial number, you're ready to reactivate the radio.

Many drivers get stuck at this stage because input process can look different across radio versions, but it's usually quick.

When the radio shows CODE, it means the unit is waiting for the correct numbers.

In-depth Entering Instructions for 300C 2020

To enter the code on the 2020 Chrysler 300C Uconnect 4C:

  1. Turn ignition to ON. Screen shows "ENTER CODE".
  2. Tap each digit of your 4-digit code on the touchscreen keypad.
  3. Radio unlocks after the 4th digit. No confirm button needed.

3 wrong attempts trigger a 60-minute lockout. Keep ignition ON for the full wait. Switching off restarts the timer.

The Correct Way to Enter It

Once the unlock code is in hand, the 2020 Chrysler 300C Uconnect head unit can be unlocked directly at the dash - no scan tool or dealer visit required.

  1. Limited attempts: Mopar/Uconnect head units only accept three incorrect tries before the radio drops into a WAIT state, so verify every digit before pressing it.
  2. Place the ignition in RUN/ACC so the radio powers up but the engine stays off.
  3. Wait for the display to show CODE, Please enter Anti-Theft Code, or a similar prompt.
  4. On the Uconnect 4C 8.4 (UAQ/UAS), tap the on-screen number pad and confirm with the OK/Enter touch button.
  5. If a 7-inch UAG is fitted, 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.
  6. 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.

Why Did the Radio Lock and Ask for a Code?

The 2020 Chrysler 300C RA4 activates anti-theft after battery is disconnected. It's a factory theft deterrent across all 300 variants.

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 dead from storage

Code comes from the radio serial number — not the VIN.

Understanding Unlock Issues with Your 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. Press each digit on the on-screen keypad. Auto-unlocks 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.

Re-read the label 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 no code prompt appears, the lock hasn't fired. Trigger the prompt: briefly disconnect the battery, reconnect, turn to ON.
