How to find Chrysler 300C 2011 radio serial number

Steps to Unlock Your 2011 Chrysler 300C Radio

To get the code, you'll take only 4 easy steps.

  1. Find the radio's serial - this is the only information required to generate the correct unlock code.
    Unlike when contacting the dealer, no VIN or paperwork is needed.
  2. When you've found the S/N, type it into the form above.
    The system checks it against a database of supported radios and automatically finds the matching radio code.
  3. In most cases, the code appears instantly on the screen after you pay and is also sent to your email , just in case.
    If manual verification is required (rare situations), you'll be informed before checkout.
  4. When you get it, simply enter it into your radio to restore full functionality.

Inputting the Security Code

After receiving 2011 Chrysler 300C unlock code from the S/N, you're ready to reactivate the radio.

Some drivers hesitate at this stage because input process can look different across radio versions, but it's usually simple.

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

The Correct Way to Enter It

To type in the unlock code on your 2011 Chrysler 300C's MyGIG RER navigation radio:

  1. Turn the ignition to ON or ACC. The display will show "ENTER CODE" or four dashes (----).
  2. Use the touchscreen number pad to input each digit of your 4-digit unlock code.
  3. Once you enter all 4 digits, the radio will unlock automatically.

Warning: Inputting the incorrect code 3 times triggers a temporary lockout. Do not turn off the ignition for approximately 60 minutes to restore the code input.

Step-by-Step Code Input Guide

  1. Limited Attempt Warning (read first). Mopar Uconnect units (and the base RES receiver) typically allow up to three attempts to enter a valid 4-digit anti-theft code. After three successive invalid entries, the radio enters a WAIT (or LOCK) state and the display will show WAIT. To exit this state, the ignition must be left in the RUN position with the radio powered for a continuous 30 minutes, after which the CODE prompt returns and a valid code can be entered. Do not power-cycle the radio during the cooldown - it generally resets the timer.
  2. Power up. Turn the ignition to RUN or ACC and wait for the radio to finish booting and display the CODE / ENTER CODE prompt.
  3. Entry on a Uconnect Touch 8.4 (RBZ / RE2 or RHR / RB5): use the on-screen numeric keypad to enter each of the four digits in order. When the fourth digit is in, an OK / GO button becomes active.
  4. Confirm on the touchscreen. Tap OK / GO to submit. If the code is correct, the radio leaves anti-theft mode and returns to normal operation; if it is rejected, the unit will count it as one of your three attempts.
  5. Entry on the base RES (single-CD) radio, if fitted: with the ignition in RUN, the display shows CODE. Use the station preset buttons (1-4 or the labelled numeric keys) to dial in each of the four digits, then press the dedicated enter/OK button (or briefly hold preset 5/6 depending on labelling) to confirm. The display returns to normal play mode if the code is accepted.
  6. If the code is rejected. Stop, double-check the code against your paperwork, and start a fresh entry from the first digit on the next attempt. Never burn the third attempt on a guess - it is far cheaper to wait 30 minutes for the lockout to clear than to risk further escalation.
  7. Tip. Tap each digit deliberately - rapid double-taps on the touchscreen can register an extra digit and inadvertently submit an incorrect entry.

Locate the Serial Number Needed to Generate Chrysler 300C 2011 Radio Code

The first part is to find the radio's S/N.

Depending on the radio unit fitted in your 2011 300C, the S/N can usually be found either through the screen menu or by pulling the unit out and checking the label on the radio itself.

Below are the most common methods to identify your S/N quickly.

Factory Radios on the 2011 Chrysler 300C

The 2011 model year launched the all-new LX-platform Chrysler 300C and brought a fresh head-unit lineup. As the luxury trim of the 300, the 300C ships with the larger touchscreen as standard, but identifying which exact radio is in your dash determines where the serial number is printed and how the security-code prompt appears on screen.

  1. Uconnect Touch 8.4 (sales code RBZ / RE2) - Standard on the base 300C. Large 8.4-inch color touchscreen mounted high on the center stack with very few physical buttons. The home screen shows tiles for Radio, Media, Climate, and Phone but no Nav tile, and there is no navigation splash at boot. Includes CD, USB, Bluetooth, SiriusXM, and voice command.
  2. Uconnect Touch 8.4N with Garmin Nav (sales code RHR / RB5) - Optional on 300C and standard on 300C with the navigation package. Visually identical bezel and 8.4-inch screen as the non-nav 8.4, so the giveaway is on the screen itself: a Nav tile on the home page and a Garmin logo at boot. Adds factory GPS navigation, SiriusXM Travel Link, and 19-speaker Harman Kardon premium audio when paired with the higher-spec packages.
  3. Base AM/FM/CD (sales code RES / RE6 family) - rare on 300C - The non-touchscreen RES/RE6 CD receiver was the base option across the 300 lineup but is uncommon on 300C cars, since 300C left the factory with the Uconnect Touch 8.4 as standard equipment. If you are inspecting an early-build or fleet-spec car, check for a small monochrome display, a single CD slot, and physical hard buttons.

Quickest visual check: large 8.4-inch glass screen with no Nav icon = 8.4 (RBZ/RE2); same 8.4-inch screen with a Nav icon and Garmin boot splash = 8.4N (RHR/RB5); small non-touch display with a CD slot and hard buttons = RES/RE6 base.

Screen-Based Serial Lookup Method

Try the following for your 2011 Chrysler 300C:

The 2011 Chrysler 300C may be equipped with the MyGIG RER 730N navigation radio. As a limitation, this system does not have a built-in Dealer Mode for displaying the serial number on the display. The serial number is not available through the touchscreen menu on MyGIG units.

The only reliable method to find the serial number is to pull the unit out and read the label on the top or side of the unit. Some owners have found the serial number on paperwork from the original purchase or in the vehicle's maintenance history, but the label on the radio itself is always the safest bet.

Check the Serial by Pulling Out the Radio Unit

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

Most Chrysler 300C OEM radios include a tag with the serial number printed on the casing.

Basic process:

  • Ensure the ignition is off.
  • Lift away surrounding mounting frame.
  • Loosen screws holding the radio.
  • Slide outward to inspect the label.

For the 2011 Chrysler 300C with the MyGIG nav unit, the radio sits in the center of the dashboard and is secured by 4 screws.

  1. First, carefully prying off the center bezel around the head unit. Use a plastic trim tool to avoid damage.
  2. Unscrew the four Phillips screws at each corner.
  3. Ease the radio out gently – watch for the wiring harness behind the unit.
  4. The serial number is on a silver sticker on the chassis, usually near the manufacturer info.

Tip: Take a photo the label prior to reinstalling the radio in case you need it again.

View Serial by Pulling Out the Radio Unit

  1. Why removal is the trustworthy method. On the 2011 Chrysler 300C (LX platform), the most reliable way to read the radio serial number is to release the head unit from the center stack and inspect the manufacturer label printed on the chassis. Whether the car has the Uconnect Touch 8.4 (RBZ/RE2), the navigation-equipped 8.4N (RHR/RB5), or (rarely on 300C) the base RES single-CD receiver, the procedure is essentially the same.
  2. Safety first. Turn the ignition fully off and remove the key, disconnect the negative battery terminal, and wait at least a few minutes before working around the dash to allow any SRS/airbag capacitors to discharge. Avoid pulling on yellow airbag harnesses, and do not yank on connectors - release their locking tabs first.
  3. Tools you should have ready. A set of plastic pry/trim tools (or a small flat-blade screwdriver wrapped in tape to protect paint), a #2 Phillips screwdriver, and a small parts tray for the four screws that secure the radio chassis.
  4. Pop the center bezel. The trim bezel that surrounds the radio and HVAC controls is held in place by spring clips and pops outward when pulled at the edges. Start at one of the lower corners with a plastic trim tool and work your way around, freeing the metal clips along the perimeter. Some clips can stay behind in the dash holes - retrieve them and re-seat them on the bezel.
  5. Disconnect bezel-mounted controls. Tilt the loose bezel toward you and disconnect the hazard switch connector at the top and the climate control connectors behind it so you can fully set the bezel aside.
  6. Unbolt the radio chassis. With the bezel out of the way, you will see four Phillips screws holding the radio chassis to the dash brackets - remove all four and slide the unit out toward you.
  7. Disconnect the rear connectors. Release the locking antenna connector and pull it free, then unplug the multi-pin electrical harness(es) at the back of the unit.
  8. Find and record the S/N. The 14-character serial number (commonly starting with T) is printed on a white or silver sticker on the top, side, or rear of the metal chassis, usually next to the Mopar/Chrysler part number and a barcode. Write it down exactly as it appears - characters are case sensitive and zeros and the letter O are easy to confuse.
  9. Reinstallation tips. Photograph the label for a clear, zoomable copy, use a piece of painter's tape on the dash to set the trim tool against to avoid scuffing the soft-touch finish, and label the harness connectors if you plan to leave the radio out for any length of time.

Standard Serial Number Patterns on This Radio

The 2011 Chrysler 300C with a MyGIG RER 730N nav radio usually features serial numbers in these formats:

  • TM9 prefix – Typical for Harman-manufactured MyGIG head units
  • T00AM prefix – Used on some Continental-manufactured models

The S/N is typically 14 characters long and is alphanumeric. Ensure you copy the serial number, not the part number (which begins with P05064 or similar). The part number describes the radio model, while the serial is tied to your specific unit.

Typical Serial Number Formats for 2011 Chrysler 300C Radios

  1. RBZ / RE2 (Uconnect Touch 8.4, no nav): commonly begins with T00-style prefixes such as T00AM or T00BE, followed by digits to make up the full 14-character string. This is the most common factory 8.4 unit on 2011 300C cars.
  2. RHR / RB5 (Uconnect Touch 8.4N with Navigation): commonly begins with TM9 followed by a numeric sequence (for example, a pattern resembling TM9XXXXXXXXXXX). These are the navigation-equipped 300C variants.
  3. RES (Base AM/FM/CD, rare on 300C): typically a 14-character alphanumeric string commonly beginning with the letter T, followed by a model/family identifier and a production sequence printed on the chassis label.
  4. What to ignore on the label: any leading whitespace, dashes, or an S/N or SER prefix is formatting only - the value to submit is the contiguous 14-character alphanumeric serial.
  5. Caveat: always verify the printed value against the chassis label - prefixes can vary between production runs and supplier batches, and an entry that is one character off will be rejected by the radio.

Why Did the Radio Lock and Ask for a Code?

The MyGIG radio lock engages automatically whenever the unit loses power. This is intentional — a removed radio becomes non-functional to anyone without the correct code.

The typical cause is a battery replacement or disconnect. Removing the battery cuts power to the radio, and on reconnection the lock activates.

Other common causes:

  • A failed radio fuse — replaced fuse triggers the lock
  • Pre-owned purchase without the original radio code
  • Workshop service that required a battery disconnect
  • A completely dead battery from not being driven

The unlock code is generated from the radio's serial number, not the vehicle VIN. It works regardless of the radio has been moved to a another vehicle.

Fixing Common Code Entry Problems for 2011 300C

The most common reason for a rejected code is a misread serial. On MyGIG units the label carries two different numbers — the part number (starts with P05064... or P05150...) and the serial number (14-char alphanumeric, begins with TM9 or T00AM). Only the serial generates the unlock code.

Go back and verify each character you entered, paying attention to the digit 0 vs. the letter O. If you're confident the serial is right, contact support for a free re-check — we verify before re-generating.

The label on the back of the MyGIG unit shows several codes. Use only the 14-character alphanumeric serial, which starts with TM9 or T00AM.

  • Part number (do NOT use): starts with P05064, P05150, or 68...
  • Serial number (use this): 14 chars, e.g. TM94881234567AA

The serial is usually printed directly below the barcode on the label. Don't mistake the part number with the serial — they look similar but serve different purposes.

If the MyGIG screen shows the normal home screen without displaying a code, the lock may not have activated. The system locks only when it senses a disconnection.

To force the code request: pull the radio fuse and reinsert it, then reconnect and turn the ignition to ON. The screen should show "ENTER CODE" within seconds of booting.

Also worth noting that certain MyGIG units take 20-30 seconds to initialize — wait at least 30 seconds after turning the ignition ON before assuming the prompt won't appear.

The MyGIG RER uses a touchscreen number pad for code entry — no numbered buttons are involved. Just touch each digit directly on the on-screen keypad.

If taps aren't registering, try a firm direct press. Don't use fingernails, gloved fingers, or anything that blocks touch.

MyGIG enters a timed lockout after 3 wrong code attempts. The touchscreen shows "ENTER CODE" but won't accept all digit input until the timer resets.

How to exit the lockout:

  1. Keep the ignition in ON or ACC — do not turn it off.
  2. Wait the full 60 minutes without touching the screen.
  3. When the lockout period ends, input is accepted again.

Turning the ignition off at any point resets the timer to zero.
