What Caused the Radio to Lock?
Challenger owners encounter this more than some other models because:
- Seasonal storage and battery drain — Many Challengers sit over winter, and prolonged storage depletes the charge and triggers the anti-theft.
- Battery replacement — standard battery service 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 original unlock code means the radio is locked on arrival.
The unlock code is permanently linked to the serial number and remains valid indefinitely.
Step-by-Step Dodge Challenger 2022 Radio Code Retrieval Guide
Car radios use security codes dependent on the radio unit itself instead of the model or production year.
- Our lookup service works by matching your Dodge Challenger radio's serial number.
- Once the serial number is submitted, the system identifies the radio unit and generates the code that you need.
- Simply input the digits into the Challenger stereo.
- The online process is quicker and more accessible than visiting the Dodge dealer.
How to Find the Serial Number on Your 2022 Dodge Challenger Radio?
The first step is to locate the radio's S/N.
Based on the head unit type installed in your 2022 Challenger, the S/N can be accessed either through the display menu or by pulling the unit out and checking the label on the radio itself.
Follow the steps below to identify your serial quickly.
Radios Offered in the 2022 Challenger
For 2022 the Challenger still uses the Uconnect 4 family. The same three head units split across the trim ladder, with screen size and navigation being the main visual differences.
- Uconnect 4 (
UAG) - 7-inch non-NAV touchscreen. Standard on 2022 SXT and GT, and on base R/T. Visual ID: 7-inch screen sitting centrally with dash trim filling the rest of the opening; Apple CarPlay and Android Auto are present, but there is no factory NAV/Map app. By volume this is the most common radio in 2022. - Uconnect 4 (
UCQ) - 8.4-inch non-NAV touchscreen. Optional on R/T, Scat Pack and many GT cars. Visual ID: large 8.4-inch screen that fills the bezel opening, CarPlay and Android Auto supported, but no NAV tile and no on-board maps. - Uconnect 4C NAV (
UAQ) - 8.4-inch touchscreen with built-in GPS. Standard on SRT Hellcat (and Hellcat Redeye/Jailbreak) and a common option on R/T Scat Pack. Visual ID: same 8.4-inch glass and bezel as UCQ, but the home screen carries a dedicated NAV/Map tile and SRT Performance Pages is unlocked.
Easiest field check: 7-inch screen = UAG, 8.4-inch with no Map tile = UCQ, 8.4-inch with a Map tile and SRT pages = UAQ.
Display-Based Serial Number Retrieval
These are the steps you need to follow for 2022 Dodge Challenger:
The 2022 Dodge Challenger's last-generation Uconnect 4C (RA4) 8.4" touchscreen is mounted in the retro-styled muscle coupe's wide center console. Retrieving 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 2022 Challenger units, Dealer Mode could be disabled after a software update. If the bezel press fails, physical removal is the fallback.
Before Removing the Radio, Try This Screen Method
The 2022 Challenger continues with the Uconnect 4 family (7-inch UAG, 8.4-inch UCQ non-NAV, 8.4-inch UAQ 4C NAV). On these units the easiest way to read the radio serial is the hidden dealer-mode screen reached from the climate panel.
Uconnect 4 (UAG / UCQ / UAQ)
Turn the ignition to RUN and let the radio finish booting. On the driver side of the climate panel, press and hold the front defrost button, the temperature UP button, and the temperature DOWN button at the same time. Keep all three pressed for around 5 to 7 seconds until the dealer/diagnostic interface replaces the normal home screen. Find the radio identification entry - the serial number is a 14-character alphanumeric string used for Mopar code lookup. Record the value exactly, then exit the menu or cycle the ignition to return to normal mode.
If the diagnostic screen does not appear after several attempts, the software on your unit may have it locked out, in which case you should fall back on reading the label from the radio chassis directly.
Pulling Out the Radio to See the S/N on the Tag
If the serial number cannot be accessed through menu, use the hardware method.
Most Dodge Challenger OEM radios include a sticker with the serial number printed on the chassis.
Basic process:
- Disable power.
- Carefully remove surrounding panel pieces.
- Loosen screws holding the radio.
- Slide outward to inspect the label.
Should Dealer Mode be unavailable on your 2022 Challenger, removing the RA4 radio exposes 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 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 side or top.
The 14-character serial is on a barcode sticker. Wiring can remain connected.
Locate Serial on Challenger's Radio Chassis
If the screen method fails, the manufacturer label on the chassis carries the same serial. The 2022 Challenger keeps the one-piece center bezel layout used since 2019, so you need to release the bezel first.
Safety preparation
Place the ignition in OFF and remove the key fob from the cabin. Disconnect the negative battery terminal and wait at least 10 to 15 minutes for the SRS/airbag capacitors to discharge fully. Stay clear of yellow airbag connectors during the job. Working with the dash at room temperature reduces the chance of marking the soft-touch surface.
Tools you will want
You will need a set of plastic trim/panel removal tools (a metal screwdriver almost always leaves marks on this trim), a Phillips #2 screwdriver or short 1/4-inch driver for the four retaining screws, and a clean surface to set the bezel on once it is out.
Removal overview
Start at the bottom edge of the center stack bezel and use a trim tool to release the spring clips. Work the perimeter until the bezel pops free, then pull it straight back. The bezel comes off as one assembly carrying the Start/Stop switch and surrounding controls, so disconnect the small harnesses on its back before setting it aside. Remove the 4 Phillips screws securing the radio cage to the dash, slide the unit forward, and unplug the antenna and main multi-pin connectors at the back.
Where the serial label sits
The label is usually on the top or one side of the metal housing - look for a barcode and a long alphanumeric string distinct from the part/finis number. Photograph the label as a backup before refitting the radio. If you do not feel confident releasing the bezel without scratches, this is a quick job for a dealer technician or trim shop.

Typical Serial Number Examples for 2022 Challenger
The 2022 Dodge Challenger Uconnect 4C (RA4) serial number features these formats:
T00AM– Primary Harman prefix for this platformT00BE– Continental-manufactured variant
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 distinct from the part number (P... or 68...) on the same label. The serial alone is needed for the unlock code.
Common Serial Number Structures
For 2022 Challenger units, the serial format depends on which supplier built your specific Uconnect 4 module - more than one vendor was used during this generation. A frequently seen pattern starts with T00 followed by two letters and a numeric tail, structured into roughly 14 characters in total - this layout is associated with Mitsubishi Electric-built Uconnect modules. Some 8.4-inch UAQ 4C NAV units use a different alphanumeric format associated with Harman builds.
The serial shown in dealer mode and the serial on the chassis label should always match exactly - cross-check both before submitting the value to a code retrieval service. Strip out any leading S/N text, dashes, or whitespace and submit only the core alphanumeric block.
Because suppliers and software builds varied within this generation, treat any pattern list as a guide rather than a strict rule. The reading from your own radio is the only definitive value.
Entering the Radio Security Code
Now that you've generated 2022 Dodge Challenger radio code from the serial, you're ready to reactivate the radio.
Some drivers get stuck at this stage because input process can look different across radio versions, but it's usually easy.
When the radio shows dashed lines, it means the unit is waiting for the correct numbers.
In-depth Entering Instructions for Challenger 2022
Code entry on the 2022 Challenger with Uconnect 4C:
- Ignition ON. The Challenger's 8.4" screen shows "ENTER CODE".
- Use the touchscreen on the on-screen keypad to enter your 4-digit code.
- The radio auto-unlocks after the 4th digit — no confirm button needed.
Lockout Warning: 3 wrong entries = 60-minute lockout. Keep the Challenger's ignition ON. Turning it off restarts the wait.
Step-by-Step Correct Entering Process
After you receive the anti-theft code, the 2022 Challenger Uconnect 4 unit accepts it through the audio preset buttons. The radio 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 state. If the lockout activates, the radio must stay powered with the ignition in RUN for 30 continuous minutes before another try is permitted. Repeated wrong-code lockouts can extend that wait significantly, so verify every digit before you press a preset.
Entry sequence
Switch the ignition to RUN so the radio is fully powered. Wait for the anti-theft prompt to appear - it typically shows as a CODE message or an Enter Anti-Theft Code dialog. Use radio presets 1 through 0 to enter 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 if the unit prompts you. The radio returns to its normal source once the correct sequence is accepted.
If a correct-looking code is rejected, check the radio serial value you submitted and confirm that the VIN tied to the code matches the vehicle the radio is currently installed in - a VIN mismatch is the most common reason an apparently correct code is refused.
Troubleshooting Common Radio Problems - Challenger 2022
The RA4 label on the Challenger shows two distinct identifiers:
- Serial number — 14 characters, starting with
T00AMorT00BE. Submit this. - Part number — begins with
P05or68. Do not submit this.
Dealer Mode via bezel corner press is most reliable method: System Info → Radio Part Info → Serial Number. No tools required.
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.
- Check the fuse box for the Challenger's radio fuse — fuse failure stops the radio.
- 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.
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.
After three failed entries on the Challenger's Uconnect 4C, a 60-minute lockout activates. The screen shows "WAIT":
- Keep the ignition in the ON position — car can be off but key cannot be cycled.
- Be patient for the full 60 minutes.
- Cycling the ignition resets the timer.
Once the lockout clears, try again with the verified code.
The Challenger's Uconnect 4C uses touchscreen-only input for code entry — no physical preset buttons are involved. When "ENTER CODE" is on screen:
- Tap each digit on the on-screen number pad.
- The Challenger's Uconnect unlocks after the final digit — no separate submit needed.
If taps don't register, cycle the ignition and wait 30 seconds.
