Can't Find Your Radio S/N? Follow These Steps for Dodge Charger 2020
The first step is to find the radio's serial num.
Depending on the radio unit fitted in your 2020 Charger, the S/N can usually be found either through the screen menu or by checking the label on the radio itself.
Below are the most common methods to identify your serial the right way.

These are the steps you need to follow for 2020 Dodge Charger:
The 2020 Dodge Charger's last-run Uconnect 4C (RA4) 8.4" touchscreen is mounted in the performance sedan's center stack. The serial number is retrievable directly on screen via Dealer Mode:
- Turn ignition to ACC or ON.
- Press the bottom-left and bottom-right corners of the physical screen bezel (the plastic frame, not the glass) simultaneously for 5 seconds.
- Dealer Mode opens on the display.
- Select: System Info → Radio Part Info → Serial Number.
Note Some 2020 Charger units may have Dealer Mode restricted after a software update. If the bezel press doesn't respond, physical radio removal is required.
Charger's Hardware Label Method
If the serial does not appear on display, the next step is checking the radio itself.
Many Dodge radios require physical access to the serial sticker attached to the unit.
Common approach:
- Start by completely shutting off the engine - pull the key out.
- Then detach the radio surround.
- Next, unscrew the mounting points and slide the radio forward.
- Look for a barcode label showing the serial number.
If Dealer Mode is unavailable on your 2020 Charger, the RA4 radio needs to be removed to read the serial label. The Charger's cockpit-style center stack makes the procedure manageable:
- Remove the center stack bezel – The Charger's bezel frames the 8.4" display. Work a plastic trim tool at the lower edge to pop off the friction-clipped panel.
- Remove the 4 Torx T20 screws – Holding the radio frame to the dash structure.
- Pull the unit forward – Ease the radio out enough to read the serial label on the top or side.
The 14-character serial is on a barcode sticker. Wiring don't need to be unplugged.

Serial Number Format Guide for 2020 Dodge Charger
Year Dodge Charger Uconnect 4C (RA4) serial number formats:
T00AM– Standard Harman prefix for Uconnect 4C unitsT00BE– Continental-sourced version
Radio designation: RA4 (Uconnect 4C, 8.4"). Serial: 14 characters (e.g., T00AM5028A1842). The final-generation Charger ran this platform through its last model year in 2024.
Note: The serial number is not the same as the part number (begins with P or 68). The serial alone generates the unlock code.
Code Entry Process for 2020 Charger
After locating the serial number and received the unlock code, the final step is entering it into your radio.
Dodge factory radios display a locked screen when ready for input.
The process is usually quick, but button layouts and confirmation methods may change depending on the radio version installed in your Charger.
Step-by-Step - Correct Entering Process
Entering the unlock code on the 2020 Charger's Uconnect 4C:
- With ignition ON, the screen displays "ENTER CODE" with an on-screen keypad.
- Tap each digit of your 4-digit code on the Charger's 8.4" touchscreen.
- The radio auto-unlocks after the 4th digit — no separate confirm.
Lockout Warning: 3 wrong attempts = 60-minute lockout. Leave the Charger's ignition ON. Turning it off resets the timer.
Understanding Unlock Issues with Your Charger
Three wrong entries on the Charger's Uconnect 4C cause a 60-minute lockout, showing "WAIT":
- Keep the Charger's ignition in the ON position — engine off is fine but key cannot be cycled.
- Wait the full 60 minutes.
- Turning the Charger off resets the timer.
After 60 minutes, re-enter with the correct code.
The RA4 label in the 2020 Charger contains multiple numbers:
- Serial number — 14 characters, prefixed by
T00AMorT00BE. Submit this. - Part number — starts with
P05or68. Do not use this.
Dealer Mode via bezel corner press is most reliable way: System Info → Radio Part Info → Serial Number. No removal required.
A rejected code on the Charger's RA4 usually means the serial was misread. The label has the serial (14-char code beginning with T00AM or T00BE) and the part number (P... or 68...) — only the serial generates a code.
Re-verify via Dealer Mode and reach out for a free re-check if needed.
If the Charger's screen doesn't show after a battery event:
- Confirm the ignition is fully ON (not ACC) and give the system a moment to boot.
- Inspect the radio fuse — fuse failure stops the radio.
- On some 2020 Charger units, a software update may delay the code prompt — tap the screen once to trigger it.
If the screen stays dark, power issue is worth checking first.
The Charger's Uconnect 4C uses touchscreen-only input for code entry — no physical preset buttons are involved. Once "ENTER CODE" shows:
- Press each number on the virtual keypad.
- The Charger's Uconnect unlocks after the final digit — no confirm button needed.
Should the screen not respond, cycle the ignition and wait 30 seconds.
Why Did the Radio Lock and Ask for a Code?
Final-generation Charger owners face this primarily due to:
- Battery replacement — routine battery service causes the code prompt on any Uconnect-equipped vehicle including the Charger.
- Seasonal storage and battery drain — muscle sedans left parked over winter drain enough to trigger the anti-theft.
- Performance electrical work — owners who disconnect the battery for mods will trigger the lock.
- Used purchase — buying a used Charger without the original unlock code means the radio is locked on arrival.
The unlock code is permanently linked to the serial number and remains valid indefinitely.
