Why Did the Radio Lock and Ask for a Code?
Owners of this full-size SUV face this primarily because of:
- Towing-related electrical work — Durango owners who add trailer wiring or work on the electrical system for trailer setups will encounter this.
- Battery replacement — larger SUVs can wear batteries faster, making replacements more frequent, and each one locks the radio.
- Long periods unused — SUVs used seasonally can drain enough to trigger the anti-theft.
- Used purchase — second-hand purchase without the prior owner's code leaves the radio locked.
The unlock code is permanently assigned to the RA3 serial number and always remains valid.
How to Find the Serial Number on Your 2015 Dodge Durango Radio?
The initial step is finding the radio serial.
Most drivers assume the code depends on the Dodge model or year, but in reality, the unlock process depends on the unique radio's serial number.
The serial is the key used to calculate the correct unlock code.
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 used, you can retrieve the serial directly from the display or by checking the label on the radio chassis.
2015 Durango - Which Radio Did You Get?
The 2015 Durango carried over the same three Harman-supplied head units used in 2014, so identification still comes down to screen size and whether NAV appears on the home screen.
- Uconnect 5.0 (sales code RA2) - base radio on SXT; recognisable by its compact 5-inch colour display surrounded by hard buttons and rotary knobs, with no touchscreen NAV. This is the most frequently encountered 2015 Durango head unit.
- Uconnect 8.4 (sales code RA3) - mid-tier option; recognisable by the full-width 8.4-inch touchscreen integrated into the dash bezel, with no NAV icon on the home menu. Common across Limited and R/T trims.
- Uconnect 8.4N (sales code RA4) - top-tier option, standard on Citadel; same 8.4-inch screen as the RA3 but the home menu carries a NAV tile and FM playback shows an HD Radio logo. Less common than the RA3 in 2015.
Before Removing the Radio, Try This Screen Method
The method for 2015 Dodge Durango is this:
The 2015 Dodge Durango seats up to 7 passengers and comes with the Uconnect 8.4" (RA3) touchscreen positioned high in the console. The serial number is accessible directly on screen via Dealer Mode.
Climate Button Method:
- Turn the ignition to ACC or ON.
- In the Durango's upright center stack, locate the Climate Up, Climate Down, and Front Defrost buttons below the 8.4" screen. Hold all three at the same time for 5 seconds.
- Dealer Mode appears on screen.
- Go to: System Info → Radio Part Info → Serial Number.
Alternative: Hold Temperature Up (red) and Temperature Down (blue) simultaneously for 5 seconds to open Engineering Mode, then navigate as above.
Access the S/N via the Radio Screen
2015 Durango 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 5.0 (RA2) does not have a documented on-screen serial method.
Uconnect 8.4 (RA3) and Uconnect 8.4N (RA4)
- 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.
Find the S/N by Pulling Out the Radio
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.
Usual approach:
- Start by completely powering down the engine - pull the key out.
- Then detach the dashboard bezel.
- Next, release the mounting points and move the radio forward.
- Look for a printed tag showing the serial number.
If Dealer Mode is inaccessible on your 2015 Durango, the RA3 radio needs to be removed to read the serial label. The Durango's elevated console makes the bezel easy to approach:
- Remove the center stack trim – The Durango's trim panel frames the 8.4" screen and climate controls. With a trim removal tool, work from the lower edges to release the clip-secured panel.
- Remove the 4 Torx T20 screws – Found at the corners of the radio frame.
- Slide the unit out – Ease the radio forward just enough to read the serial label on the side or top of the unit.
The serial is a 14-character code on a barcode label. Wiring can remain attached while you record the serial.
Find the S/N by Pulling Out the Unit
If the screen-based shortcut is unavailable - for instance on the base Uconnect 5.0 - the printed serial label can still be reached by carefully extracting the head unit from the centre stack of the 2015 Durango.
- 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, 7 mm socket, Phillips screwdriver, small Torx bit set, flashlight.
- Pry the centre dash bezel out with a plastic trim tool, starting at the bottom edge and working up the sides; the Durango bezel is held by hidden clip retainers rather than exposed screws.
- Unplug the hazard switch and the HVAC/control connectors at the rear of the bezel before laying it on a clean cloth.
- Remove the four 7 mm bolts (two upper, two lower) 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 a printed barcode/sticker 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.

Got the Code? Here's How to Enter It
When you obtain the correct unlock code based on the serial number, you can restore default functionality by entering it into the unit.
The code entry process depends on the radio interface, but most 2015 Durango systems follow a similar structure using preset buttons, touch controls, or rotary knobs - depending on if it's a factory or an aftermarket unit.
You will typically see CODE displayed on screen.
Correct Entering Process

- With ignition ON, the screen displays "ENTER CODE".
- Tap the on-screen number pad to enter each digit of your 4-digit code on the Durango's 8.4" display.
- The radio confirms automatically after the 4th digit — no additional step is needed.
Lockout: 3 incorrect attempts = 60-minute lockout. Leave the Durango's ignition ON. Turning it off resets the timer.
Step-by-Step Correct Entering Process
Once the unlock code is in hand, the 2015 Durango radio can be unlocked directly at the head unit - no scan tool or dealership visit required.
- Limited attempts: Mopar/Uconnect head units only accept three wrong tries before entering a WAIT 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 the 8.4 Uconnect units (RA3/RA4), type the digits using the on-screen number pad; on the base Uconnect 5.0 (RA2), press the numbered preset buttons in sequence.
- Confirm with the on-screen OK/Enter button, or with the tune/menu knob on the RA2.
- If
WAITappears after three incorrect attempts, leave the ignition in RUN with the radio powered for a continuous 30 minutes before trying again with the correct code.

Fixing Common Code Entry Problems for 2015 Durango
In the 2015 Durango, all code entry is via the 8.4" touchscreen — no physical buttons are used. Once "ENTER CODE" is shown:
- Press each number on the touchscreen number pad.
- The radio unlocks after the final number — no confirm button is needed.
If the Durango's touchscreen is unresponsive, cycle the ignition and wait 30 seconds.
Three wrong code entries on the Durango's Uconnect activate a 60-minute lockout, showing "WAIT" on screen:
- Leave the ignition ON in the Durango — the Durango doesn't need to be running but ignition must stay in ON.
- Wait for the entire 60 minutes.
- Turning the Durango off restarts the lockout.
Once the 60 minutes are up, try again with the verified code.
A rejected code on the Durango's Uconnect 8.4" almost always means a serial number error. The label shows both the serial (14 characters, starts with T00AM, T00BE, or TM9) and the part number (P... or 68...) — only the serial generates the code.
Double-check the serial on the Durango's display or the label and contact support for a free re-check if needed.
When no "ENTER CODE" appears after a battery event:
- Ensure the ignition is fully in ON (not ACC) and allow the system a moment to boot.
- Inspect the radio fuse in the Durango under the hood or under the dash. A blown fuse stops the display.
- Tapping the display may trigger the code prompt on certain Durango units.
Should nothing appear, a blown fuse is the first thing to investigate.
The RA3 label in the Durango lists multiple identifiers:
- Serial number — 14 alphanumeric characters, starting with
T00AM,T00BE, orTM9. This is the one you submit. - Part number — begins with
P05064or68. Not needed.
On the Durango, Dealer Mode is the quickest way: System Info → Radio Part Info → Serial Number. No removal required.
