Why Did the Radio Lock and Ask for a Code?

The 2017 Chrysler 300C RA3 locks automatically after any power disconnection. Even the premium 300C trim uses the same security system — a disconnected radio is useless without the code.

Most common cause: battery replacement or disconnect. Other causes:

  • Failed fuse after electrical work
  • Buying the 300C pre-owned without a known code
  • Battery disconnect for service
  • Battery drained from not driving

Code is tied to the radio serial number — not the VIN.

How to Get Your 2017 Chrysler 300C Radio Code

Vehicle radios use security codes tied to the radio unit itself rather than the model or production year.

  • Our lookup service works by matching your Chrysler 300C radio's serial number.
  • Once the serial number is submitted, the system identifies the radio unit and retrieves the corresponding code.
  • Simply input the digits into the 300C stereo.
  • The online process is quicker and more accessible than visiting the Chrysler dealer.

Can't Find Your Unit's Serial Number? Follow The Steps Below for Chrysler 300C 2017

The initial step is locating the radio S/N.

Most drivers assume the code depends on the Chrysler model or year, but actually, the unlock process depends on the unique radio unit's serial number.

Each radio has its own serial tied to the security system.

This is actually better, because if you have a used radio, the VIN or other Chrysler-specific data wouldn't be of much use.

Based on the radio used, you can see the serial directly from the display or by looking at the label on the radio chassis.

Factory Radios on the 2017 Chrysler 300C

2017 is the final year of the original LD-facelift Uconnect lineup before the 4C generation became dominant. On 300C and 300C Platinum trims the standard head unit is still the 8.4-inch Uconnect 8.4 NAV (RA4), but late-build cars can also ship with the new Uconnect 4C 8.4 NAV (UAQ) that introduced Apple CarPlay and Android Auto. The exact head unit depends on build date and option box.

  1. Uconnect 8.4 NAV / RA4 - the legacy standard radio on the 300C. 8.4-inch landscape touchscreen with the Garmin nav database, HD Radio and SiriusXM Traffic / Travel Link. A Nav tile sits on the home screen and the SiriusXM Traffic splash appears at start-up.
  2. Uconnect 8.4 / RA3 - the same 8.4-inch hardware as the RA4 but without factory navigation. Less common on a 300C; generally seen on order-specific cars where the nav option was deselected.
  3. Uconnect 4C 8.4 NAV / UAQ - the new-generation 8.4-inch nav head unit on late-build 2017 cars. Visually similar to the RA4 bezel but with Apple CarPlay and Android Auto tiles available when a phone is plugged in via USB.
  4. Uconnect 4C 8.4 / UAS - the non-nav variant of the 4C generation, occasionally seen on late-build 300C orders without the nav option.

Quick tell: 8.4-inch screen with no CarPlay tile and a Nav tile = RA4; 8.4-inch screen with no CarPlay tile and no Nav tile = RA3; 8.4-inch screen that shows Apple CarPlay / Android Auto when a phone is plugged in and a Nav tile = 4C UAQ; same with no Nav tile = 4C UAS. The sales code is printed on the label on top of the radio chassis - pull the bezel and check the housing to confirm.

Accessing the Serial Number Through the Radio Menu

These are the steps you need to follow for 2017 Chrysler 300C:

The 2017 Chrysler 300C — Chrysler's HEMI V8 flagship sedan — is equipped with the Uconnect 8.4" Classic (RA3). The 300C's premium interior features the same climate control cluster below the 8.4" screen used to trigger Dealer Mode.

Press and hold Climate Up, Climate Down, and Front Defrost simultaneously for 5 seconds (ignition in ACC or ON). Dealer Mode opens on the display. Navigate to: System Info → Radio Part Info → Serial Number.

Read the Serial Number From the Touchscreen

For 2017 Chrysler 300C cars fitted with an 8.4-inch Uconnect, the head unit supports a hidden dealer / diagnostic menu that displays the radio's internal serial number. The shortcut is the same on the older RA3 / RA4 and on the newer Uconnect 4C UAS / UAQ.

Uconnect 8.4 (RA3, RA4, 4C UAS, 4C UAQ)

  1. Place the ignition in RUN so the touchscreen is fully booted.
  2. Press and hold the driver's temperature UP, temperature DOWN and front DEFROST buttons together for around 7 seconds.
  3. When the dealer / diagnostic menu opens, choose the radio-information entries near the top of the list - they list serial numbers, hardware and software revisions and similar identifiers.
  4. Note the full serial exactly as printed, including any leading letters such as T00AM, TM9 or A2C.
  5. Press Done, or cycle the ignition off and on, to leave the menu.

If the dealer-mode shortcut does not bring up a serial entry on your specific car, the chassis-label method covered in the radio-removal block is the dependable fallback.

Check the Serial by Pulling Out the Radio

If the serial number cannot be accessed through menu, use the pull-out method.

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

Step-by-Step Approach:

  1. Power down the vehicle.
  2. Lift the bezel surrounding the radio.
  3. Unscrew the clips.
  4. Slide the unit forward to access the label.

The serial number is usually located near the barcode.

If Dealer Mode is unavailable on the 2017 Chrysler 300C, the RA3 unit can be removed from the 300C's luxury center console. The 300C's premium bezel may require extra care when prying off the trim bezel.

  1. Carefully remove the premium center bezel with a plastic trim tool — avoid scratching the premium trim.
  2. Remove the four Torx T20 mounting screws.
  3. Slide the unit out to read the serial label on the top or side of the radio chassis.

Releasing the Head Unit to See the S/N Tag

If you cannot reach the hidden menu - for example because the radio is locked at the CODE prompt and the touchscreen is unresponsive - the chassis label is the most reliable source for the serial number on a 2017 Chrysler 300C.

Safety preparation

  1. Turn the ignition fully off and remove the key fob from the cabin.
  2. Disconnect the negative terminal of the 12V battery.
  3. Wait several minutes before working near the dash so any airbag-related circuits can fully discharge.
  4. Stay clear of yellow airbag wiring while pulling trim.

Tools to have ready

  1. Plastic trim / panel pry tools to release bezel clips without marking the dash.
  2. A driver that matches the four radio retaining screws (typically Phillips or 7 mm).
  3. A phone or camera to photograph the chassis label clearly.

Removal overview

  1. Beginning at a lower edge, gently pry the centre dash bezel that surrounds the radio and HVAC controls. On the 2017 LD 300C the bezel is held by retaining clips rather than bolts.
  2. Walk the pry tool around the perimeter until each clip releases.
  3. Pull the bezel forward and unplug the small connectors on its back (hazard switch, clock and climate controls).
  4. Undo the four retaining screws now visible at the corners of the radio chassis.
  5. Slide the head unit out and disconnect the main wiring harness and the antenna lead.

Where the serial sits

  1. Look for a thermal-printed label on the metal chassis - usually on the top or one side of the housing.
  2. Copy the long alphanumeric string next to the barcode, double-checking ambiguous characters (O vs 0, I vs 1).

Tips

  1. Photograph the label before refitting so the serial is preserved as a reference.
  2. Reassembly is the reverse of removal - harness back on, four screws home, bezel pressed in until each clip seats, then reconnect the battery.

Typical Radio Serial Prefixes and Formats

The 2017 Chrysler 300C HEMI RA3 radio serial formats:

  • T00AM – Harman VP2 RA3 — most common in the 300C premium trims
  • T00BE – Continental variant of the 8.4" system
  • TM9 – Earlier Harman production

Serial is 14 alphanumeric characters. Part number on the same label starts with P05064 or 68 — that's not the serial.

Typical Serial Number Examples for the 2017 Chrysler 300C

The 2017 Chrysler 300C could leave the factory with one of several Uconnect 8.4 head units, each from a different supplier, so the serial-number style varies by radio. The patterns below are the ones most often reported by owners and unlock services for this generation - treat them as guidance rather than a guarantee.

Continental-supplied Uconnect 8.4 (RA3 / RA4)

  1. Frequently start with a T00AM prefix followed by a numeric tail, for example a string resembling T00AM1234567.
  2. The prefix is printed inline with the rest of the serial on the chassis label.

Continental-supplied Uconnect 4C 8.4 (UAS / UAQ)

  1. Newer Continental 4C-generation head units fitted to late-build 2017 cars are sometimes associated with an A2C-style prefix in addition to the legacy T00AM.
  2. The printed label on the chassis remains the authoritative source.

Panasonic-supplied Uconnect units

  1. Often start with TM9 followed by additional digits or letters.
  2. This pattern has been widely reported on Panasonic-built Mopar radios across the Uconnect 8.4 era.

If the alphanumeric you read does not match any of these examples, double-check that you have copied the serial line and not the part number. The serial is normally the longest string on the label and is the one tied to the barcode.

Radio Code Input Guide

Once the system gives you 2017 Chrysler 300C radio code from the serial, you're ready to reactivate the radio.

Many drivers get stuck at this stage because input methods 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.

Step-by-Step Code Input Guide

Entering the unlock code the 2017 Chrysler 300C's Uconnect 8.4":

  1. Turn ignition to ON. The screen shows "ENTER CODE".
  2. Tap each digit to enter your 4-digit code.
  3. Radio unlocks automatically after the 4th digit.

3 wrong attempts trigger a 60-minute lockout. Keep ignition ON for the full duration without switching off.

Detailed Code Entry Instructions for Chrysler 300C 2017

Once you have the correct anti-theft code for your 2017 Chrysler 300C radio, entry on the screen is fast - but the radio will lock itself out for half an hour if you keep entering wrong codes, so verify the code before you start.

Limited Attempt Warning

Only three attempts are allowed before lockout. Three consecutive wrong codes place the radio in a WAIT state and the display reads WAIT. To clear it, the radio must remain powered with the ignition in RUN for a continuous 30 minutes. The vehicle may be driven during that time, but cycling the key off does not bypass the timer.

Entering the code

  1. Turn the ignition to RUN or ACC so the radio powers up and shows the CODE / Anti-Theft prompt.
  2. On the 8.4-inch Uconnect (RA3, RA4, 4C UAS or 4C UAQ), tap each digit on the touchscreen number pad.
  3. Confirm with the OK / Enter on-screen control or the equivalent hardware button.
  4. When the code is accepted, the radio returns to its normal home screen and audio resumes.

If it does not unlock

  1. Stop after the second wrong attempt and recheck the serial you used to obtain the code.
  2. Make sure no leading letters or trailing digits were dropped from the serial.
  3. If WAIT appears, leave the radio powered with the ignition in RUN for the full 30 minutes before retrying.

If the 300C Uconnect boots normally, anti-theft isn't engaged. Trigger the prompt by briefly disconnecting the battery, then reconnect and turn to ON.

3 wrong entries lock the 300C's RA3 for 60 minutes. Keep ignition in ON or ACC for the full 60 minutes. Turning off restarts the timer from zero.
