How the Code Retrieval Process Works for Dodge Challenger 2019
Car radios use anti-theft codes dependent on the radio unit itself instead of the vehicle model or production year.
- The system uses the Challenger's radio serial to retrieve the unlock code.
- When you input the serial into the generator, the system identifies the radio unit and retrieves the corresponding code.
- Simply input the digits into the Challenger stereo.
- This approach saves time compared to traditional methods for 2019 Dodge Challenger.
Can't Find Your Radio S/N? Follow These Steps for Dodge Challenger 2019
The important thing to know is that factory radios use a unique S/N to identify each unit.
The anti-theft system links the code directly to the serial.
Different from vehicle-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 maker and radio installed in your Dodge Challenger, the access method is different.
Here are the best ways to locate it.
View the Serial on the Radio Screen
Try the following for your 2019 Dodge Challenger:
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.
Taking 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 chassis.
Step-by-Step Approach:
- Turn off the vehicle.
- Detach the dashboard frame surrounding the radio.
- Loosen the clips.
- Move the unit slightly out to access the label.
The serial number is usually located near the manufacturer sticker.
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.

Typical Radio Serial Prefixes and Formats
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.
Got the Code? Here's How to Enter It
Now that you've found the S/N and received the unlock code, the next step is entering it into your radio.
Dodge OEM units display a locked screen when ready for input.
The process is straightforward, but button layouts and confirmation methods may differ slightly depending on the radio version installed in your Challenger.
Entering Process Explained
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.
Why Did the Radio Lock and Ask 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.
Challenger 2019 Common Radio Problems
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.
