How To Retrieve Your Dodge Car Radio Code
If your Dodge radio is showing “CODE” or “LOC” after a battery change, flat battery, radio swap, or electrical repair, you can request the unlock code online using the radio serial number.
This guide explains how to retrieve your Dodge car radio code, where to find the serial number on the unit, and what to check before placing your request.
Enter your Dodge serial number
Most Dodge radio serial numbers start with T and are 14 characters long.
How to find your Dodge radio serial number
To generate the correct code, you need the serial number printed on your Dodge radio. On older models, the unit usually has to be pulled out of the dash to check the label on the casing. On newer Uconnect radios, the serial number can sometimes be read straight from the screen, under a menu such as “System Info” or “About Radio”.

Look for a sticker on the back or side of the unit. The serial often begins with the letter T.
Use the full serial
Enter the complete serial exactly as shown. Missing or swapped characters may generate the wrong result.

If you’re not sure which characters count, take a clear photo of the radio label before placing your request.
Popular Dodge radio code guides
Dodge fitted several different factory radio and infotainment units over the years, sourced from brands like Alpine, Harman, and Panasonic. Some drivers have a simple single-DIN Alpine unit, while others have a full Uconnect touchscreen. The unlocking process is similar for all of them, but each unit has its own serial format and button sequence.

Most Dodge factory radios include a built-in anti-theft security system. After a battery replacement, flat battery, radio swap, or electrical interruption, the unit may lock itself and display “CODE” or “LOC” before it can be used again.
This feature is designed to stop a stolen radio from being reused in another vehicle. In most cases, the original code can still be recovered using the serial number printed on the radio casing, without needing a dealer visit.
Dodge factory radios are commonly manufactured by brands such as Alpine, Harman, Panasonic, Continental, and Delphi, and are fitted across the Charger, Challenger, Durango, Journey, Caliber, Avenger, Nitro and Ram ranges. Most of these units use serial numbers beginning with the letter T, while newer Uconnect systems may show a longer alphanumeric reference on screen.
Before requesting a code, double-check that the serial number has been entered correctly. A single incorrect character can generate the wrong result. If the label is worn, scratched, or hard to read, taking a clear close-up photo of the sticker can help avoid mistakes.
Some Dodge radios will temporarily lock after several incorrect code attempts. If this happens, the radio usually needs to stay powered on for a set period before another attempt can be made.
How to enter the Dodge car radio code
After receiving the code, turn on the radio and wait for the CODE screen to appear. On most Dodge units, you’ll enter each digit using preset buttons 1 to 4: press button 1 repeatedly until the first digit is shown, then repeat with buttons 2, 3 and 4 until the full code is displayed. If you scroll past the digit you need, keep pressing until it cycles back around.
Once the correct code is showing, press and hold the ENTER or OK button for a few seconds to confirm it. The exact confirmation button can vary slightly depending on the radio model fitted to your vehicle.
If the radio still shows CODE or LOC afterward, avoid entering random numbers repeatedly. Too many incorrect attempts can extend the waiting time before you’re allowed to try again.
