Why Did the Radio Lock and Ask for a Code?
This vehicle encounters radio lockouts most commonly because of:
- Battery disconnect or replacement — the single most common cause on all Uconnect-equipped vehicles including the Dart.
- Young used-car buyers — the Dart was popular as a first car, meaning many change hands without the code.
- Dead battery — smaller vehicles left sitting sometimes lose enough charge to trigger the anti-theft.
- Blown fuse — a fuse failure also triggers the lock.
Regardless of the trigger, the unlock code is permanently tied to the radio serial and remains valid.
Can't Find Your Radio Serial Number? Follow These Steps for Dodge Dart 2015
The initial step is finding the radio serial number.
Many people assume the code depends on the Dodge model or year, but actually, the unlock process depends on the unique radio's serial number.
Each radio has its own serial tied to the security system.
This is even better, because if you have bought a used radio, the VIN or other Dodge-specific data wouldn't be of much use.
Based on the radio version used, you may be able to see the serial directly from the display or by checking the label on the radio chassis.
Identify Your 2015 Dart's Factory Radio
Pinpointing your 2015 Dodge Dart's exact head unit makes locating the serial number and entering the unlock code straightforward, since each radio displays the code-entry prompt slightly differently.
- Uconnect 200 (RAE) - The base radio, standard on SE and many SXT cars. A compact head unit with a small monochrome display, a CD slot, and physical hard buttons surrounding it. No color touchscreen, no Nav button. This remains the most common factory radio in 2015 Darts because it was fitted to the highest-volume trim levels.
- Uconnect Touch 8.4 (RE2) - Optional on mid trims and standard on Limited/GT. A large 8.4-inch color touchscreen with minimal physical buttons, mounted prominently in the center stack. The home screen shows tiles for Radio, Media, Climate, Apps, and Phone, but does not show a Nav tile. Includes CD, USB, Bluetooth, SiriusXM, and voice command.
- Uconnect Touch 8.4N (RB5) - The navigation-equipped 8.4-inch unit. Outwardly identical bezel and screen size as the RE2, so the easiest way to tell them apart is to look at the home screen: if there is a Nav tile (and a Garmin splash on startup), you have the 8.4N. Adds factory GPS navigation and SiriusXM Travel Link.
Quick test: tap the screen. No response and small display = Uconnect 200. Touch responds and a Nav icon is visible = RB5. Touch responds but no Nav icon = RE2.
Using Hidden Radio Menus to Find the Serial
Try the following for your 2015 Dodge Dart:
The 2015 Dodge Dart could feature either the Uconnect 5.0" (base trim) or Uconnect 8.4" (higher trims). If equipped with the 8.4" screen, you can try Dealer Mode:
- Turn ignition to ACC or ON.
- Hold Climate Up + Climate Down + Front Defrost for 5 seconds.
- Navigate to: System Info → Radio Part Info → Serial Number.
On the 5.0" Uconnect, Dealer Mode is not supported. The radio must be pulled out to access the serial label.
Screen-Based Serial Lookup Method
2015 Dart models with the 8.4-inch Uconnect screen include a hidden dealer/diagnostic menu that prints the head-unit serial number directly on the touchscreen, so the radio does not need to come out of the dash. The base Uconnect 200 head unit does not have a documented on-screen serial method.
Uconnect 8.4 (RE2) and Uconnect 8.4N (RB5)
- Place the ignition in RUN/ACC and wait for the Uconnect screen to fully load.
- 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.
- Open the radio or system info section to view the serial number printed on screen.
- Snap a photo of the screen so the characters can be copied across without errors.
Taking Out the Radio Unit to See the S/N on the Tag
If the serial number cannot be accessed through menu, use the removal method.
Most Dodge Dart OEM radios include a sticker with the serial number printed on the casing.
The process:
- Shut down the car.
- Carefully remove surrounding mounting frame.
- Release clips holding the radio.
- Pull forward to inspect the label.
To remove the radio from the 2015 Dodge Dart:
- Turn off the vehicle.
- Carefully pry the trim panel around the radio. The Dart uses plastic clips.
- Remove the four mounting bolts (Phillips).
- Pull the radio out to access the serial label.
The Dart's dashboard is not overly complex. The trim clips typically pop off without much force with a plastic pry tool.
Pulling Out the Radio Unit to Access the S/N on the Tag
If the screen-based method is not an option (for example on the base Uconnect 200), the printed serial label can still be accessed by carefully extracting the radio from the centre stack of the 2015 Dart.
- Safety first: turn the ignition off, remove the key, disconnect the negative battery terminal, and wait a few minutes; never disturb the yellow airbag/SRS connectors and use plastic trim tools to keep clips and metal contacts intact.
- Tools you will need: plastic trim removal kit, Phillips screwdriver, small Torx bit set, flashlight.
- Pry the centre dash bezel out with a plastic trim tool starting at the bottom edge - the Dart bezel is a single moulded panel held by hidden clips.
- Unplug the hazard switch and any HVAC connectors at the rear of the bezel before laying it on a clean cloth.
- Remove the four Phillips screws (two top, two bottom) that secure the radio cage to the support bracket.
- Slide the radio straight rearward and disconnect the antenna and the multi-pin power/data harness on the back of the unit.
- The serial number lives on the printed barcode label on the top or side of the radio chassis, alongside the part number.
- Photograph the label and double-check easily confused characters such as 0/O and 1/I before submitting the serial.

These are the Common Serial Formats
The 2015 Dodge Dart uses Uconnect radios with these typical serial formats:
T00AM– Harman Uconnect (8.4") unitsT00BE– Continental variantsTM9– First-year production units
Radio models: RA1 (5.0" base), RA3 (8.4" with nav option). The Dart was produced from 2013-2016 only and used the Fiat Compact Wide platform, but the Uconnect system is the identical as other Dodge vehicles.
Standard Serial Number Patterns on This Radio
The factory head units fitted to the 2015 Dart follow the standard Mopar/Continental serial pattern, with the prefix varying by supplier and Uconnect tier.
Uconnect 8.4 (RE2) and Uconnect 8.4N (RB5)
- Typically printed as a 14-character alphanumeric string on the chassis label.
- Commonly begins with
T- frequent prefixes includeT00AM,TM9andTQ1- or withA2Con Continental-supplied variants. - Often runs as continuous letters and digits with no spaces or dashes.
Uconnect 200 (Base CD)
- Usually carries a Mopar/Harman-style serial on a chassis sticker; the label on the unit itself is the authoritative source.
- Always copy the serial exactly as printed and avoid guessing unclear characters.
Entering Your Unlock Code
Once you have the radio serial and retrieved the unlock code, the next step is entering it into your radio.
Dodge factory radios display a locked screen when ready for input.
The process is usually straightforward, but button layouts and confirmation methods may change depending on the radio version installed in your Dart.
Entering Process Explained
To input the code on the 2015 Dodge Dart's Uconnect:
- Ignition ON. Screen displays "ENTER CODE".
- Use the touchscreen keypad to enter each digit of the 4-digit code.
- Radio auto-unlocks after the 4th digit.
Lockout: 3 wrong attempts = 60-minute lockout. Keep ignition ON during the entire wait period.
Step-by-Step Correct Entering Process
Once the unlock code is in hand, the 2015 Dart radio can be unlocked directly at the head unit - no scan tool or dealership visit required.
- Limited attempts: Mopar/Uconnect head units accept only a small number of wrong tries (commonly three) before entering 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. - On 8.4 Uconnect units, type the digits using the on-screen number pad; on the base Uconnect 200, press the numbered preset buttons in sequence.
- Confirm with the on-screen OK/Enter button, or with the tune/menu knob on the base unit.
- If
WAITappears after incorrect attempts, leave the ignition in RUN with the radio powered for the documented cool-down period (around 30 minutes) before trying again with the correct code.
Unlock Your 2015 Dodge Dart Radio in Minutes - How It Works
- Rather than relying on Dodge dealership lookup or online threads you can generate the code online using the radio S/N.
- First locate your radio's serial. The best place to search is on the unit itself, and in some cases you can see it on the Dart's radio screen.
- Type it into the generator above, and the system will generate the correct 2015 Dart unlock code.
- After getting it, type it in using Dart's radio buttons to unlock the system successfully.
- The entire process takes less than a minute for most users and requires minimal effort.
Troubleshooting Common Radio Problems - Dart 2015
Both Uconnect trims in the Dart use the touchscreen exclusively for code entry. Whether you have the 5.0" and the 8.4" both use an on-screen keypad — no physical preset buttons are used during code entry.
- Touch each digit on the on-screen pad.
- The radio unlocks automatically after all four digits are entered.
If the screen is not responding, cycle the ignition once and wait 20 seconds for the system to restart.
After 3 failed code attempts on the Dart's Uconnect triggers a 60-minute lockout. The screen shows "WAIT". To clear it:
- Keep the ignition ON for the entire 60 minutes — do not turn the car off.
- Cycling the ignition extends the wait.
Dart note: Because the Dart was popular with younger buyers who may not know the lockout rule sometimes cycle the ignition to "fix" it. Don't do this — just be patient.
If your Dart has the larger screen, use Dealer Mode to retrieve the serial: press and hold Climate Up + Climate Down + Front Defrost for 5 seconds, then navigate to System Info → Serial Number. On the smaller screen, physical removal is required to see the label.
- Serial number — 14 characters, starting with
T00AM,TM9, orT00BE. - Part number — starts with
Por68. Do not use this.
The Dart used the Fiat Compact Wide platform, the Uconnect serial format is standard as all other Dodge vehicles.
If the Dart's radio does not show after a battery event:
- Make sure the ignition is in the ON position — the radio needs full power.
- Check the radio fuse — a blown fuse stops the radio from powering on.
- Give the system 10–20 seconds to start before expecting the "ENTER CODE" prompt.
On the 5.0" base Uconnect, the display is smaller but the code prompt behavior is identical.
As an affordable compact, meaning a lot of buyers bought second-hand and may have the wrong code history. If the code is rejected, the usual reason is using the part number instead of the serial. The Dart's Uconnect serial is 14 characters, starting with T00AM, T00BE, or TM9. The part number (P... or 68...) sits nearby and should not be submitted.
If rejected, double-check the number and reach out for a free re-check.
