Can't Locate Your Radio Serial Number? Follow The Steps Below for Dodge Viper 2013
The useful thing to know is that factory radios use a unique S/N to identify each unit.
Your anti-theft system links the code directly to this serial.
Unlike car-specific data like VIN or registration info, it is not determined by the model or production year, so you'll be able to generate it even if you have a radio that you bought afterwards.
Depending on the maker and radio installed in your Dodge Viper, the retrieval method is different.
Here are the most reliable ways to locate it.
Factory Radios on the 2013 Dodge Viper
2013 is the launch year of the fifth-generation ZB Viper, sold under the SRT brand (badged as SRT Viper, not Dodge Viper, for 2013-2014). FCA simplified the head-unit choice on the halo car: every 2013 SRT Viper, SRT Viper GTS and TA shipped with the same 8.4-inch Uconnect touchscreen, paired with a Harman Kardon premium amplifier and speaker package. There is no base radio option on the Viper.
- RA4 - Uconnect 8.4AN (Viper-specific 8.4) with Harman Kardon premium audio: standard on every 2013 SRT Viper. 8.4-inch portrait touchscreen with hard buttons across the bottom (Radio / Media / Climate / Phone / Apps / Nav) and tactile volume and tune knobs flanking the display. The unit is built by Harman and shares its core hardware with the wider Uconnect 3C/8.4AN family used in Ram, Charger and Grand Cherokee, but ships with a Viper-themed UI and is paired with the 7-inch reconfigurable digital instrument cluster.
- Harman Kardon premium audio (standard): SRT Viper uses a Harman Kardon high-voltage class-D amplifier with up to 12 channels and high-efficiency GreenEdge speakers. SRT Viper GTS adds the Harman Kardon Logic 7 surround system with up to 18 speakers including four behind-the-seat subwoofers; the head unit itself is the same 8.4AN/RA4.
- Quick visual check: if the centre stack has an 8.4-inch portrait touchscreen with the Viper snake logo on the boot/splash screen, you have the 8.4AN/RA4. There is no smaller 5-inch RA2 or older MyGig option on this car.
Before Removing the Radio, Try This Screen Method
Try the following for your 2013 Dodge Viper:
The 2013 Dodge Viper (5th generation, VX) features the Uconnect 8.4" touchscreen system (the same platform other same-era Dodge vehicles). You can find the serial number via Dealer Mode:
- Turn ignition to ACC or ON.
- Hold the Climate Up, Climate Down, and Front Defrost buttons together for 5 seconds.
- Go to: System Info → Radio Part Info → Serial Number.
Note: The Viper's sports car dashboard layout may have modified climate button placement compared to sedans. Check the climate buttons on the lower center console.
Find Your Serial Number on the Radio Display
The 2013 SRT Viper uses the Harman-built 8.4AN/RA4 Uconnect, which is the same family as the 8.4-inch Uconnect 3C used elsewhere across FCA. That family exposes a hidden dealer/diagnostic menu that prints the head-unit serial number directly on the touchscreen, so the radio normally does not have to come out of the dash.
- Switch the ignition to RUN/ACC and wait for the Uconnect screen to finish booting.
- Press and hold the driver-side temperature UP, the driver-side temperature DOWN, and the front DEFROST buttons together.
- Keep all three buttons held for roughly 7-10 seconds until the dealer/diagnostic interface opens.
- Browse to the radio or system information section to view the serial number printed on screen.
- Photograph the screen so each character can be transcribed accurately.
Manufacturer Label Inspection
If the serial number cannot be accessed on-screen, use the removal method.
Most Dodge Viper original radios include a tag with the serial number printed on the housing.
Step-by-Step:
- Switch off the vehicle.
- Remove the dashboard frame surrounding the radio.
- Release the mounting bolts.
- Pull the unit outward to access the label.
The serial number is usually located near the barcode.
If Dealer Mode is inaccessible on your 2013 Viper, the Uconnect 8.4" radio needs to be removed. The Viper has a unique dashboard layout:
- Use a trim tool to remove the carbon fiber trim bezel around the infotainment screen.
- Remove the 4 mounting bolts (Torx T20).
- Slide the unit forward, careful with the tight space in the Viper's cockpit.
- Read the serial number on the sticker on the unit top or side.
Tip: Due to the Viper's low cockpit, some owners find it easier reaching from the other side for more room.
View Serial by Pulling Out the Radio Unit
If the on-screen shortcut is unavailable on a particular SRT Viper - for example because the Uconnect cannot fully boot - the printed chassis label on the back of the radio is the most reliable source for the serial number. The Viper's centre stack is tightly packaged around the 7-inch digital cluster wiring, so work slowly. If you are not comfortable with airbag-adjacent trim work, professional service is recommended.
- Safety first: turn the ignition off, remove the key, disconnect the negative battery terminal, and wait several minutes before touching wiring; avoid the yellow airbag/SRS connectors entirely and use plastic trim tools so nothing shorts or breaks.
- Tools you will need: plastic trim removal kit, Phillips screwdriver, small Torx bit set, flashlight.
- Engage the parking brake and pop the centre dash bezel free with a plastic pry tool, working slowly around the panel so the hidden retaining clips release without cracking the trim.
- Disconnect the HVAC/climate control connector and the hazard-switch connector at the rear of the bezel before setting it aside on a clean cloth.
- Remove the screws (typically four Phillips, two upper and two lower) holding the radio cage to the dash support bracket.
- Slide the radio straight rearward and disconnect the antenna lead and the multi-pin power/data harness on the back of the unit.
- The serial number lives on a printed barcode/sticker label on the top, side, or rear of the radio chassis, alongside the Harman part number and supplier markings (RA4 / 8.4AN).
- Photograph the label up close and double-check easily confused characters such as 0/O and 1/I before submitting the serial.

Steps to Unlock Your 2013 Dodge Viper Radio
To get the code, you'll take only a few easy steps.
- Find the radio's serial - this is the only info required to generate the correct unlock code.
Unlike dealership lookup, no VIN is needed. - Enter the serial number into our generator above.
The system checks it against a database of supported factory radios and automatically retrieves the matching anti-theft code. - In most cases, the code appears instantly on the screen after you pay and is also sent to your email for backup.
If we need to check it manually, you'll be notified before checkout. - Once you get it, simply enter it into your radio to restore full functionality.
Entering the Radio Security Code
After locating the S/N and received the unlock code, the last step is entering it into your radio.
Dodge factory radios display a ENTER CODE message when ready for input.
The process is usually quick, but button layouts and confirmation methods may vary depending on the radio version installed in your Viper.
In-depth Entering Instructions for Viper 2013
To input the code on the 2013 Viper's Uconnect 8.4":
- Ignition ON. Screen shows "ENTER CODE".
- Tap the touchscreen keypad for each digit of the 4-digit code.
- Radio unlocks automatically after the 4th digit.
Lockout: 3 incorrect attempts = 60-minute lockout. Keep ignition ON. The Viper's code unlock method is the same as all other Uconnect 8.4" vehicles.
Step-by-Step Code Input Guide
Once the unlock code has been retrieved, the 2013 SRT Viper's Uconnect 8.4AN/RA4 radio is unlocked directly at the head unit - no scan tool or dealer visit is required.
- Limited attempts: Mopar/Uconnect head units only accept a small number of incorrect tries (commonly three) before going into a WAIT/LOCK state, so confirm every digit before pressing it.
- Place the ignition in RUN/ACC so the radio powers up but the engine stays off.
- Wait for the display to show
CODE,Enter Anti-Theft Code, or a similar prompt. - Key each digit using the on-screen number pad on the 8.4-inch touchscreen.
- Confirm the entry with the on-screen OK/Enter button.
- If
WAITappears after incorrect attempts, leave the radio powered with the ignition in RUN for the documented cool-down period (around 30 minutes of continuous run-state) before trying the correct code again.
Troubleshooting Common Radio Problems - Viper 2013
If the Viper's radio does not display after a power restoration:
- Ensure full ignition ON and wait 15–20 seconds for the radio to boot.
- Check the fuse panel — a blown fuse will prevent the radio from powering on.
- Certain Viper units may require a screen tap to wake the code screen after the system initializes.
Should the display remain blank, a blown fuse is the first thing to check.
The Viper's Uconnect 8.4" uses the touchscreen number pad exclusively for code entry. Once "ENTER CODE" is on screen:
- Press each digit on the digital keypad.
- The radio auto-confirms after the final number.
In the Viper's low driving position, the center console touchscreen carefully. No physical preset buttons is needed during code entry.
After 3 failed attempts on the Viper's Uconnect triggers the standard 60-minute lockout. The screen shows "WAIT". To handle it:
- Leave the ignition ON for the entire 60 minutes.
- Switching off the Viper restarts the lockout countdown.
Viper note: Sports cars like the Viper are often stored which causes battery discharge — this means battery events are common and the same lockout rules apply.
Even on a supercar, the Uconnect 8.4" radio functions the same as on any other Dodge vehicle. A rejected code indicates the wrong serial was used. The label shows both the serial (T00AM or TM9, 14 characters) and the part number (P... or 68...) — only the serial generates the unlock code.
If rejected, use Dealer Mode to verify the serial and reach out for a free re-check.
The Viper's Uconnect 8.4" serial can typically be accessed via Dealer Mode without any physical removal. Go to System Info → Radio Part Info → Serial Number. It will be a 14-character code starting with T00AM or TM9.
Should you need to pull the radio, be aware that the Viper's sports car dashboard has limited space around the center stack. The label also shows a part number (P... or 68...) — use only the serial.
Why Is the Radio Asking for a Code?
The Viper experience radio lockouts with notable frequency because of how they are used:
- Battery drain from storage — Sports cars are often stored for months at a time, draining the battery enough to trigger the anti-theft.
- Trailering and transport — each time power is cut for trailer transport, the radio locks again.
- Battery replacement — any battery service will trigger the lock.
- Used purchase — buyers acquiring without documentation will need the code immediately.
The unlock code is tied to the serial number and remains valid indefinitely.
