Finding the Radio S/N for Dodge
The starting step is locating the radio serial.
Most people assume the code depends on the Dodge model or year, but in reality, the whole process relies on the unique radio unit's serial number.
This number identifies the exact head unit installed in your Dodge Durango.
This is even better, because if you have an aftermarket radio, the VIN or other Dodge-specific data wouldn't help.
Based on the radio version used, you may be able to retrieve the serial directly from the display or by checking the label on the radio chassis.
Quick Method: Find the Serial Number on the Screen
Try the following for your 2018 Dodge Durango:
The 2018 Dodge Durango is a three-row full-size SUV and comes with the Uconnect 8.4" (RA3) touchscreen elevated in the SUV's tall center stack. The serial number can be found directly on screen via Dealer Mode.
Climate Button Method:
- Turn the ignition to ACC or ON.
- In the Durango's upright center stack, find the Climate Up, Climate Down, and Front Defrost buttons on the climate panel beneath the display. Press and 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.
Taking Out the Radio to See the S/N on the Tag
If the serial number cannot be accessed via display, use the hardware method.
Most Dodge Durango original radios include a sticker with the serial number printed on the chassis.
The process:
- Ensure the ignition is off.
- Gently detach surrounding panel pieces.
- Remove fasteners holding the radio.
- Slide outward to inspect the label.
If Dealer Mode is inaccessible on your 2018 Durango, the RA3 radio needs to be removed to access the serial label. The Durango's tall SUV center stack makes the bezel easy to approach:
- Remove the center stack trim – The Durango's trim panel frames the 8.4" screen and climate controls. Using a plastic pry tool, work from the lower edges to release the friction-clipped panel.
- Remove the 4 Torx T20 screws – These are at the corners of the radio frame.
- Slide the unit out – Pull 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 stay connected while you record the serial.

Entering the Radio Security Code
Once you receive the correct unlock code based on the S/N, you can restore normal functionality by entering it into the unit.
The code entry process depends on the control layout, but most 2018 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.

Step-by-Step Dodge Durango 2018 Radio Code Retrieval Guide
Car radios use anti-theft codes tied to the radio unit itself rather than the vehicle model or production year.
- The generator identifies your Dodge radio via serial-based verification.
- Once the serial number is submitted, the system identifies the radio unit and retrieves the corresponding code.
- Simply input the digits into the Durango stereo.
- The online process is quicker and more accessible than visiting the Dodge dealer.
Why Did the Radio Lock and Ask for a Code?
Durango owners face this primarily because of:
- Towing-related electrical work — those installing tow packages or disconnect the battery for towing accessories will encounter this.
- Battery replacement — the Durango's higher electrical demand can wear batteries faster, making replacements more frequent, and every replacement triggers the code screen.
- Long periods unused — SUVs used seasonally can drain enough to lock the radio.
- Used purchase — second-hand purchase without the prior owner's code requires the code immediately.
The unlock code is permanently assigned to the RA3 serial number and always remains valid.
Fixing Common Code Entry Problems for 2018 Durango
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 prevents any radio power.
- A single screen tap may activate the code prompt on some Durango units.
Should nothing appear, a blown fuse is the most probable cause.
In the 2018 Durango, all code entry is via the 8.4" touchscreen — no physical buttons are involved. Once "ENTER CODE" is shown:
- Press each number on the on-screen keypad.
- The radio auto-confirms after the final number — no extra step is required.
Should the display not register taps, cycle the ignition and wait 30 seconds.
A rejected code on the Durango's Uconnect 8.4" almost always means a serial number error. The label shows both the serial (14 chars, starts with T00AM, T00BE, or TM9) and the part number (P... or 68...) — only the serial generates the code.
Re-verify via Dealer Mode and reach out for a free re-check if needed.
The RA3 label in the Durango shows multiple identifiers:
- Serial number — 14 alphanumeric characters, starting with
T00AM,T00BE, orTM9. Use this. - Part number — begins with
P05064or68. Not needed.
On the Durango, Dealer Mode is the most reliable way: System Info → Radio Part Info → Serial Number. No tools required.
Three wrong code entries on the Durango's Uconnect cause 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.
- Let the timer count down for the full 60 minutes.
- Cycling the ignition restarts the lockout.
Once the 60 minutes are up, re-enter the correct code.
