Where to Find the Serial Number on your Challenger
The important fact to know is that factory radios use a specific serial number to identify each unitindividually.
Your anti-theft system links the code directly to this serial.
Unlike car-specific data such as 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 an aftermarket radio.
Depending on the manufacturer and radio installed in your Dodge Challenger, the access method varies.
Here are the most reliable ways to locate it.
Factory Radios on the 2019 Dodge Challenger
The 2019 Challenger sits in the Uconnect 4 era, with three head units split across the trim ladder. All three are touchscreen units; the difference is screen size and whether built-in navigation is included.
- Uconnect 4 (sales code
UAG) - 7-inch touchscreen, no built-in NAV. Standard on SXT and base R/T. Visual ID: smaller centred 7-inch display with a wide black bezel surround filling the rest of the dash opening, Apple CarPlay and Android Auto support, no NAV icon in the home grid. Most common radio on 2019 cars. - Uconnect 4 (sales code
UCQ) - 8.4-inch touchscreen, no built-in NAV. Optional on R/T and Scat Pack-style trims. Visual ID: large 8.4-inch screen filling the dash opening edge to edge, Apple CarPlay and Android Auto present, no NAV tile/icon and no GPS arrow on the home screen. - Uconnect 4C NAV (sales code
UAQ) - 8.4-inch touchscreen with built-in GPS navigation. Optional on most trims, frequently standard on SRT Hellcat. Visual ID: same 8.4-inch bezel as UCQ but with a dedicated NAV/Map tile on the home screen, SRT/Performance Pages enabled, Apple CarPlay and Android Auto plus on-board maps.
If you are unsure whether your 8.4-inch unit is UCQ or UAQ, look for a NAV/Map app tile on the home screen - present on UAQ, missing on UCQ.
Quick Method: Find the Serial Number on the Screen
The method for 2019 Dodge Challenger is this:
The 2019 Dodge Challenger's last-generation Uconnect 4C (RA4) 8.4" touchscreen is set in the retro-styled muscle coupe's wide center console. Finding the serial number on screen uses Dealer Mode:
- Turn ignition to ACC or ON.
- Press the bottom-left and bottom-right corners of the physical screen bezel (the plastic frame around the glass) at the same time for 5 seconds.
- Dealer Mode opens on the display.
- Navigate to: System Info → Radio Part Info → Serial Number.
Note On some 2019 Challenger units, Dealer Mode could be disabled after a software update. If the bezel press fails, physical removal is the fallback.
Fast Serial Lookup Using Radio Controls
The 2019 Challenger ships with Uconnect 4 head units (7-inch UAG, 8.4-inch UCQ non-NAV, or 8.4-inch UAQ with 4C NAV). All three respond to a hidden dealer-mode shortcut that reveals the radio serial without removing anything.
Uconnect 4 (7-inch and 8.4-inch units)
- Switch the ignition to RUN with the radio powered on.
- On the climate panel, press and hold the front defrost button together with the temperature UP and temperature DOWN buttons (driver side) at the same time.
- Hold all three for roughly 5 to 7 seconds until the screen jumps into the dealer/diagnostic menu.
- Look for the entry that lists the radio serial number - on Uconnect 4 it is typically a 14-character string used by Mopar for code lookup.
- Write the full string down exactly as shown, then back out of the menu or cycle the ignition to return to the normal radio screen.
If the dealer menu does not appear after several attempts, the software build on your unit may have it disabled and you will need to use the radio-removal method instead.
Pulling Out the Unit to Access the S/N on the Tag
If the serial number cannot be accessed on-screen, use the hardware method.
Most Dodge Challenger OEM radios include a label with the serial number printed on the casing.
Process details:
- Disable power.
- Lift away surrounding dashboard trim.
- Release clips holding the radio.
- Slide outward to inspect the label.
Should Dealer Mode be blocked on your 2019 Challenger, removing the RA4 radio gives access to the serial label. The Challenger's 2-door coupe interior has distinctive trim:
- Remove the center stack bezel – The Challenger's trim panel covers the 8.4" screen and HVAC controls. Work a plastic pry tool around the edges – the panel starts at the lower edge first.
- Unscrew the 4 Torx T20 bolts – Securing the radio mount to the dash.
- Ease the radio forward – Pull the unit out far enough to read the serial label on the top surface.
The 14-character serial is on a barcode sticker. Cables can remain connected.
Pulling Out the Radio Unit to See the S/N on the Tag
If the on-screen method does not work, the manufacturer label printed on the radio chassis carries the same serial. The 2019 Challenger uses a one-piece center stack bezel that surrounds the screen, vents, and Start/Stop button, so a small amount of trim work is required.
Safety preparation
- Switch the ignition fully OFF and remove the key fob from the cabin.
- Disconnect the negative battery terminal and wait at least 10 to 15 minutes before touching wiring - the SRS/airbag system needs time to discharge.
- Avoid prying near airbag harnesses (yellow connectors) at all costs.
- Work on a cool dash so the soft-touch material is less prone to marking.
Tools you will want
- Plastic trim/panel removal tools (a metal screwdriver will scratch the dash).
- A Phillips #2 screwdriver or short 1/4-inch ratchet for the radio retaining screws.
- A clean cloth and somewhere to place the bezel without scuffing it.
Removal overview
- Insert a plastic trim tool at the lower edge of the center stack bezel and gently work around the perimeter to release the spring clips.
- Pull the bezel straight back - it lifts out as one piece carrying the Start/Stop switch and surrounding controls.
- Disconnect the small wiring harnesses on the back of the bezel before setting it aside.
- Remove the 4 Phillips screws securing the radio cage to the dash and slide the unit out toward you.
- Unplug the antenna lead and the multi-pin connectors from the rear of the radio.
Where the serial label sits
- Look for a white or silver sticker on the top or side of the metal chassis - it carries the part number, a barcode, and the serial number you need.
- Photograph the label so you have a clean record before reinstalling.
If you are not comfortable releasing the bezel without scratches, a trim shop or dealer technician can pop the unit in a few minutes.

How Serial Numbers Usually Look on These Challenger Radios
The 2019 Dodge Challenger Uconnect 4C (RA4) serial number features these formats:
T00AM– Standard Harman prefix for this platformT00BE– Continental-manufactured version
Radio designation: RA4 (Uconnect 4C). Serial: 14 characters. The Challenger shared this platform with the Charger in its final production years through 2024.
Serial is not the same as the part number (P... or 68...) on the same label. The serial alone is used for the unlock code.
Typical Serial Number Examples for 2019 Challenger
2019 Challenger Uconnect 4 units are typically supplied by Mitsubishi Electric or Harman, and the serial format reflects the supplier rather than a single fixed pattern.
- Many Uconnect radios show a serial that starts with T00 followed by two letters and a numeric tail (a Mitsubishi Electric pattern often described in the field as around 14 characters total).
- Some 8.4-inch 4C NAV units use a different prefix associated with Harman; the structure is alphanumeric and uppercase.
- The serial usually appears in two places that should match - the dealer-mode screen and the chassis label - so you can cross-check before requesting a code.
- If your printed string contains spaces, dashes, or a leading
S/N, ignore those characters and submit only the alphanumeric body.
Because more than one supplier was used in this generation, treat any pattern listed online as a guide rather than a strict rule. The reading from your own radio is the only definitive value.
Fast Dodge Challenger Radio Unlock Process Explained
Getting your radio code takes only 4 simple steps.
- Find your radio's serial number - this is the only information required to generate the correct unlock code.
The difference with the dealership lookup is that no VIN is needed. - Enter the serial number into our generator above.
Our system checks it against a database of supported radios and automatically finds the matching security code. - In most cases, the code will appear instantly on the screen after payment and is also sent to your email , just in case.
If we need to check it manually, you'll be notified before checkout. - When you receive it, just enter it into your radio to restore full functionality.
Entering the Radio 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 2019 Challenger 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.
Step-by-Step Code Input Guide
Code entry on the 2019 Challenger with Uconnect 4C:
- Ignition ON. The Challenger's 8.4" screen presents "ENTER CODE".
- Use the touchscreen on the on-screen keypad to enter your 4-digit code.
- The radio confirms automatically after the 4th digit — no extra step needed.
Lockout Warning: 3 wrong entries = 60-minute lockout. Keep the Challenger's ignition ON. Turning it off resets the timer.
Step-by-Step Code Input Guide
Once you have the correct anti-theft code for your 2019 Challenger radio, entry is done with the audio preset buttons. The unit will not unlock until the full sequence is accepted.
Limited Attempt Warning
- You only get a small number of attempts (typically 3) before the radio enters a lockout/WAIT state.
- If the lockout activates, you must leave the ignition in RUN with the radio powered for a continuous 30 minutes before trying again.
- Repeated wrong-code lockouts can stretch into much longer waits, so confirm every digit before you press a preset.
Entry sequence
- Turn the ignition to RUN (engine does not need to be running) and let the radio power up.
- Wait until the screen prompts for the anti-theft code - it will display a CODE prompt or an Enter Anti-Theft Code message.
- Use radio presets 1 through 0 to input each digit of the code in order. For example, for code 1234 press preset 1, then 2, then 3, then 4.
- Confirm with the OK/Enter soft key on the touchscreen if prompted.
- The radio should switch back to its normal source after the correct sequence is accepted.
If your code was issued by Mopar or the dealer tied to your VIN, double-check that the VIN you provided matches the vehicle the radio is currently installed in - a VIN mismatch is the most common reason a correct-looking code is rejected.
Fixing Common Code Entry Problems for 2019 Challenger
When no "ENTER CODE" appears after a battery event:
- Turn the ignition to ON (not ACC) and wait a moment for the Uconnect system to load.
- Inspect the fuses for the Challenger's radio fuse — fuse failure prevents the display from powering.
- Tap the touchscreen once to trigger the code entry prompt if it hasn't appeared.
If the display stays dark, power issue is worth checking first.
The RA4 label on the Challenger carries two distinct identifiers:
- Serial number — 14 characters, beginning with
T00AMorT00BE. Submit this. - Part number — begins with
P05or68. Do not submit this.
Dealer Mode via bezel corner press is the cleanest method: System Info → Radio Part Info → Serial Number. No tools required.
After 3 wrong attempts on the Challenger's Uconnect 4C, a 60-minute lockout engages. The screen shows "WAIT":
- Keep the ignition in the ON position — car can be off but key cannot be cycled.
- Wait the full 60 minutes.
- Turning the Challenger off restarts the 60-minute wait.
Once the lockout clears, try again with the verified code.
A rejected unlock code on the Challenger's RA4 typically means the wrong serial was submitted. The label has the serial (T00AM or T00BE, 14 characters) and the part number (P... or 68...) — submit only the serial.
Check the serial on screen or from the label and contact support for a free re-check if needed.
The Challenger's Uconnect 4C uses touchscreen-only input for code entry — no physical preset buttons are used. When "ENTER CODE" is on screen:
- Press each number on the on-screen number pad.
- The Challenger's Uconnect auto-confirms after the final digit — no separate submit needed.
Should the screen not respond, cycle the ignition and wait 30 seconds.
Why Is the Radio Asking for a Code?
Challenger owners encounter this more than some other models because:
- Seasonal storage and battery drain — Many Challengers sit over winter, and months without use depletes the charge and triggers the anti-theft.
- Battery replacement — any battery swap activates the code screen on any model year.
- Performance electrical work — Challenger enthusiasts who disconnect the battery for mods will encounter this.
- Used purchase — second-hand purchase without the original unlock code means the code is needed right away.
The unlock code is permanently linked to the serial number and remains valid indefinitely.
