How 2015 Chrysler 300 Radio Code Lookup Works

  • Instead of contacting Chrysler dealer or searching forums you can generate the code online with the radio serial number.
  • Start by finding the serial number. You will always find it on the unit itself, and in some cases it can be visible on the 300's radio screen.
  • Enter it into the field above, and the software will identify the correct 2015 300 unlock code.
  • After receiving your code, input it using 300's radio controls to release the blockade fully.
  • The entire process takes only a few minutes and requires no VIN, documents, or technical knowledge.

How Serial Numbers Work and Where to Find Them on 2015 Chrysler 300 Radios

Very important fact to know is that factory radios use a unique S/N to identify each unit.

The anti-theft system links the code directly to this serial.

Unlike car-specific data like VIN or registration information, 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 manufacturer and radio installed in your Chrysler 300, the retrieval method is different.

These are the most reliable ways to locate it.

Factory Radios on the 2015 Chrysler 300

The 2015 model year is the start of the LD facelift, and Chrysler retired the older MyGIG-era head units in favour of a new Uconnect generation. The lineup is split between the small 5-inch base radio and the wide 8.4-inch touchscreen, with navigation as a separate sales code on the larger unit.

  1. Uconnect 5.0 / RA2 - the entry-level head unit fitted to lower-spec 300 Limited builds where the bigger screen was not optioned. A 5-inch colour touchscreen sits between hard buttons on either side of the bezel, with no CD slot and no NAV button.
  2. Uconnect 8.4 / RA3 - the large 8.4-inch landscape touchscreen without factory navigation. Capacitive shortcut keys (Radio, Media, Controls, Climate, Phone, Apps) line the bottom of the screen, and there is no Nav tile on the home page.
  3. Uconnect 8.4 NAV / RA4 - the navigation-equipped 8.4-inch unit. Standard on 300C / 300C Platinum and optional on lower trims, it adds a Nav tile to the home screen, HD Radio, SiriusXM Traffic / Travel Link and the Garmin map engine.

Quick tell: 5-inch screen = RA2; 8.4-inch screen with no Nav tile = RA3; 8.4-inch screen with a Nav tile and a SiriusXM Traffic splash at startup = RA4.

Quick Method: Find the Serial Number on the Screen

The method for 2015 Chrysler 300 is this:

The 2015 Chrysler 300 full-size sedan is equipped with the Uconnect 8.4" Classic (RA3), which includes a hidden Dealer Mode to display the serial number on the 8.4" display.

On the 300, the Climate Up, Climate Down, and Front Defrost buttons sit directly below the 8.4" screen on the center stack. Press and hold simultaneously for 5 seconds with the ignition in ACC or ON. Dealer Mode opens. Navigate to: System Info → Radio Part Info → Serial Number.

Read the Serial Number Through the Touchscreen

On the 8.4-inch Uconnect head units fitted to 2015 Chryser 300 cars, the radio's internal serial number can usually be read from a hidden dealer / diagnostic menu. That is much faster than dropping the unit out of the dash, and it works even when the radio is at the CODE prompt provided the touchscreen still responds.

Uconnect 8.4 (RA3) and Uconnect 8.4 NAV (RA4)

  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 on the 8.4-inch screen, 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 or TM9.
  5. Press Done, or cycle the ignition off and on, to leave the menu.

Uconnect 5.0 (RA2)

For the smaller 5-inch RA2, an equivalent on-screen serial-number readout is not consistently documented for the 2015 300. If the dealer-mode shortcut does not bring up a serial entry on the RA2, fall back to the chassis-label method described in the radio-removal block.

Access the S/N by Pulling Out the Radio Unit

If the serial number cannot be accessed via display, use the hardware method.

Most Chrysler 300 OEM radios include a sticker with the serial number printed on the housing.

Steps:

  1. Turn off the vehicle.
  2. Lift the bezel surrounding the radio.
  3. Release the fasteners.
  4. Slide the unit forward to access the label.

The serial number is usually located near the printed code.

If Dealer Mode is unavailable on the 2015 Chrysler 300, remove the RA3 unit from the 300's center stack. The 300's formal upright center console gives good clearance once the bezel is off.

  1. Remove the trim panel with a plastic trim tool — held by.
  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 chassis.

Pull the Head Unit and Read the Chassis Label

If you cannot reach the hidden menu - for example because the radio is locked at the CODE prompt and the touchscreen is unresponsive - removing the head unit and reading the printed serial label on the chassis is the most dependable method on a 2015 Chrysler 300.

Safety preparation

  1. Switch 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 reaching behind the dash so any airbag-related circuits can fully discharge.
  4. Stay clear of the yellow airbag harnesses while moving trim around.

Tools you will want ready

  1. Plastic trim / panel pry tools to free the centre bezel without scratching the dash.
  2. A driver matching the four radio retaining screws (typically Phillips or 7 mm).
  3. A phone or camera to photograph the serial 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 2015 LD 300 the bezel is held by retaining clips rather than bolts.
  2. Walk the pry tool around the perimeter until each clip releases, then ease the bezel forward.
  3. Reach behind the bezel and unplug the small connectors for the hazard switch, clock and climate controls before fully removing it.
  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 is printed

  1. Look at the top, side or rear face of the metal chassis for a thermal-printed label.
  2. Copy the long alphanumeric string next to the barcode and double-check ambiguous characters (O vs 0, I vs 1).

Tips

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

Typical Radio Serial Prefixes and Formats

The 2015 Chrysler 300 RA3 radio serial formats:

  • T00AM – Harman VP2 RA3 (most common on the 300)
  • T00BE – Continental version
  • TM9 – Earlier Harman production

Serial is 14 alphanumeric chars. The part number (starts with P05064 or 68) is on the same label — ignore it.

Typical Serial Number Formats on 2015 Chrysler 300 Radios

The 2015 Chrysler 300 could leave the factory with several different Uconnect head units, each from a different supplier, so the serial-number style depends on which radio is in your car. 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 usually printed inline with the rest of the serial on the chassis label.

Panasonic-supplied Uconnect units

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

Uconnect 5.0 (RA2) base radio

  1. Also carries a printed serial label on the chassis, but the prefix can vary by supplier batch.
  2. Read the full string off the label rather than assuming a fixed format.

If the alphanumeric you read does not match any of these examples, double-check that you 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.

Inputting the Security Code

When you obtain 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 2015 300 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 SAFE displayed on screen.

Detailed Entering Instructions for 300 2015

To unlock the 2015 Chrysler 300 Uconnect 8.4":

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

Lockout: 3 wrong attempts trigger a 60-minute lockout. Keep ignition ON for the full 60 minutes. Turning off restarts the timer.

Step-by-Step Code Input Guide

Once you have the correct anti-theft code for your 2015 Chrysler 300 radio, the entry itself is fast - but the unit will lock you out for half an hour if you keep entering wrong codes, so verify the code before you start.

Limited Attempt Warning

You only get three attempts. After three wrong codes in a row the radio enters 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 period, but cycling the key off does not shortcut 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), tap each digit on the touchscreen number pad.
  3. On the 5-inch Uconnect 5.0 (RA2), enter the digits using the preset (1-6) buttons in sequence.
  4. Confirm with the OK / Enter on-screen control or the equivalent hardware button.
  5. If 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 re-verify the serial number 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 for the full 30 minutes before trying again.

What Caused the Radio to Lock?

The 2015 Chrysler 300 Uconnect RA3 self-locks whenever power is cut. A removed radio is worthless to a thief.

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

  • Blown radio fuse after electrical work or shorts
  • Buying the 300 second-hand without a known code
  • Battery disconnect for service or repair
  • Battery dead from long storage

The code is tied to the radio serial number — not the VIN. Valid in any car the unit is installed in.

Understanding Unlock Issues with Your 300

The 300 Uconnect RA3 uses touchscreen-only code entry. Touch each digit on the on-screen keypad. No physical buttons needed. Auto-unlocks after the 4th digit.

The 300's RA3 label shows both part number (P05064... or 68...) and serial. Use only the 14-character serial starting with T00AM, T00BE, or TM9. Watch out for 0 vs. O on the label.

Reach out for a free re-check if the code was rejected after a careful read.

3 wrong entries lock the 300's Uconnect RA3 for 60 minutes. The screen still shows "ENTER CODE" but won't accept input.

Keep ignition in ON or ACC for the full 60 minutes without turning off. Turning off restarts the countdown.

If the 300 screen shows the normal home screen, the anti-theft isn't active. The prompt only shows after a battery disconnect.

Trigger it: briefly disconnect the battery, reconnect, turn ignition to ON. "ENTER CODE" shows at boot.

The radio chassis label: serial = 14 alphanumeric chars starting with T00AM, T00BE, or TM9. Part number = starts with P05064 or 68 — skip this.
