How to Find the Serial Number on Your 2020 Dodge Challenger Radio?
Very important fact to know is that factory radios use a unique S/N to identify each unitindividually.
The security 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 a radio that you installed afterwards.
Depending on the manufacturer and radio installed in your Dodge Challenger, the retrieval method is different.
These are the best ways to find it.
Display-Based Serial Number Retrieval
Try the following for your 2020 Dodge Challenger:
The 2020 Dodge Challenger's final Uconnect 4C (RA4) 8.4" touchscreen is mounted 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) simultaneously for 5 seconds.
- Dealer Mode appears on the display.
- Navigate to: System Info → Radio Part Info → Serial Number.
Note On some 2020 Challenger units, Dealer Mode could be disabled after a software update. If the bezel press fails, physical removal is the fallback.
Taking Out the Radio Unit to View the S/N on the Tag
If the serial number cannot be accessed through menu, use the removal method.
Most Dodge Challenger OEM radios include a tag with the serial number printed on the housing.
Step-by-Step Approach:
- Turn off the vehicle.
- Remove the trim surrounding the radio.
- Release the mounting bolts.
- Move the unit slightly out to access the label.
The serial number is usually located near the barcode.
Should Dealer Mode be blocked on your 2020 Challenger, removing the RA4 radio gives access to the serial label. The Challenger's wide, retro-style center console has distinctive trim:
- Remove the center stack bezel – The Challenger's bezel covers the 8.4" screen and HVAC controls. Work a plastic pry tool around the edges – the panel releases from the bottom corners 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 side or top.
The 14-character serial is on a barcode sticker. Cables can remain connected.

How Serial Numbers Usually Look on These Challenger Radios
The 2020 Dodge Challenger Uconnect 4C (RA4) serial number uses 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.
The serial number is distinct from the part number (P... or 68...) on the same label. Only the serial is used for the unlock code.
Final Step - Enter the Radio Code
Once the system gives you 2020 Dodge Challenger radio code from the serial, 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 ENTER CODE, it means the unit is waiting for the correct numbers.
The Correct Way to Enter It
Code entry on the 2020 Challenger with Uconnect 4C:
- Ignition ON. The Challenger's 8.4" screen presents "ENTER CODE".
- Tap each digit on the on-screen keypad to enter your 4-digit code.
- The radio auto-unlocks after the 4th digit — no extra step needed.
Lockout Warning: 3 wrong entries = 60-minute lockout. Leave the Challenger's ignition ON. Turning it off restarts the wait.
How 2020 Dodge Challenger Radio Code Lookup Works
To get the code, you'll take only a few simple steps.
- Locate the radio's serial - this is the only information required to generate the correct unlock code.
Unlike dealership lookup, no VIN or paperwork 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 appears instantly on the screen after payment and is also sent to your email for backup.
If manual verification is required (rare situations), you'll be notified before checkout. - When you receive it, simply enter it into your radio to restore full functionality.
Why Is the Radio Asking for a Code?
Challenger owners encounter this more than some other models because:
- Seasonal storage and battery drain — The Challenger is often a weekend or summer car, and months without use drains the battery enough to lock the radio.
- Battery replacement — any battery swap activates the code screen on any model year.
- Performance electrical work — owners working on the electrical system will encounter this.
- Used purchase — second-hand purchase without the prior owner's code means the code is needed right away.
The unlock code is tied to the serial number and does not change.
Challenger 2020 Common Radio Problems
Code rejection on the Challenger's RA4 usually traces to the wrong serial was submitted. The label has the serial (T00AM or T00BE, 14 characters) and the part number (P... or 68...) — the part number does not generate a code.
Check the serial on screen or from the label and reach out for a free re-check if needed.
The RA4 label on the Challenger carries multiple numbers:
- Serial number — 14 characters, beginning with
T00AMorT00BE. This is what you need. - Part number — starts with
P05or68. Not the serial.
The on-screen Dealer Mode is most reliable method: System Info → Radio Part Info → Serial Number. No tools required.
When no "ENTER CODE" appears after a battery event:
- Ensure the key is in ON (not ACC) and allow 15–20 seconds for the Uconnect system to initialize.
- Check the fuse box for the Challenger's radio fuse — a blown fuse stops the radio.
- Try pressing the screen once to trigger the code entry prompt if it doesn't show automatically.
If the display stays dark, a blown fuse is the most likely culprit.
The Challenger's Uconnect 4C uses touchscreen-only input for code entry — no physical preset buttons are used. When "ENTER CODE" is on screen:
- Tap each digit on the virtual keypad on the 8.4" screen.
- The Challenger's Uconnect unlocks after the final digit — no confirmation button needed.
If taps don't register, cycle the ignition and wait 30 seconds.
After 3 wrong attempts on the Challenger's Uconnect 4C, a 60-minute lockout engages. The screen displays "WAIT":
- Keep the ignition in the ON position — car can be off but key cannot be cycled.
- Wait the entire 60 minutes.
- Cycling the ignition restarts the 60-minute wait.
Once the lockout clears, try again with the verified code.
