Can't Locate Your Unit's S/N? Follow These Steps for Dodge Avenger 2012
The starting step is finding the radio serial number.
Many drivers assume the code depends on the Dodge model or year, but actually, the whole process depends on the unique radio's serial number.
The serial is the key used to calculate the correct unlock code.
This is actually 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 can see the serial directly from the display or by looking at the label on the radio chassis.

The method for 2012 Dodge Avenger is this:
The 2012 Dodge Avenger mid-size sedan from this era may feature a MyGIG radio (RER 730N) or an early Uconnect system fitted in the sedan's center stack. These pre-2014 head units lack on-screen serial display.
The serial number can only be accessed by physically removing the radio from the Avenger's dashboard and locating the barcode label on the radio chassis.
Access the Serial by Pulling Out the Radio Unit
If the serial number cannot be accessed via display, use the hardware method.
Most Dodge Avenger OEM radios include a tag with the serial number printed on the casing.
Step-by-Step Approach:
- Power down the vehicle.
- Lift the dashboard frame surrounding the radio.
- Loosen the fasteners.
- Pull the unit slightly out to access the label.
The serial number is usually located near the manufacturer sticker.
To access the serial on the 2012 Avenger's radio, you must remove it from the dash:
- Turn off the vehicle.
- Use a plastic trim tool to remove the center stack bezel around the radio. The Avenger's sedan trim panel releases with friction clips – start at the bottom.
- Remove the 4 Phillips mounting screws securing the radio.
- Pull the unit forward and locate the serial label on the top, side, or back of the radio.
Be careful with the wiring harness. No need to disconnect it unless absolutely necessary.

Got the Code? Here's How to Enter It
Once you have the serial number and retrieved the unlock code, the last step is entering it into your radio.
Dodge factory radios display a CODE prompt when ready for input.
The process is quick, but button layouts and confirmation methods may differ slightly depending on the radio version installed in your Avenger.
Step-by-Step Code Input Guide
To input the unlock code on the 2012 Avenger's radio:
- Turn ignition to ON. The radio shows "CODE" or "ENTER CODE".
- Touchscreen models (REP/RBZ/RER): Tap the touchscreen number pad to enter each digit.
- Non-touchscreen models (RES/REF): Press preset button 1 repeatedly for the first digit, button 2 for the second, 3 for the third, 4 for the fourth. Hold Enter/OK to confirm.
Warning: 3+ wrong attempts trigger a lockout. Keep the Avenger's radio powered for about 60 minutes to clear it.
How the Code Retrieval Process Works for Dodge Avenger 2012
Getting your radio code takes only a few easy steps.
- Locate the radio's serial number - this is the only info required by our side.
The difference with the dealership lookup is that no VIN or paperwork is needed. - Enter the serial number into our generator above.
The system checks it against a database of supported radios and automatically catches the matching radio code. - In most cases, the code appears instantly on the screen after payment and is also sent to your email for backup.
If we need to check it manually, you'll be informed before checkout. - When you get it, just enter it into your radio to restore full functionality.
Why Is the Radio Asking for a Code?
Avenger owners from this era encounter radio lockouts primarily due to:
- Battery disconnect or replacement — the primary cause on pre-2014 Avengers.
- Aging battery failure — older Dodge sedans are prone to dead batteries which trigger the lock.
- Blown fuse — a blown radio fuse also counts as a power loss.
- Used purchase — second-hand purchase without documentation often means the code was never recorded.
Your code is permanently linked to the radio serial and never changes.
Fixing Common Code Entry Problems for 2012 Avenger
When no "CODE" screen appears after a battery event:
- Confirm the ignition is in ON (not ACC) and wait 15–20 seconds to initialize.
- Inspect the radio fuse — fuse failure stops the radio.
- On some older units, pressing any button on the radio face can wake the code prompt.
If the radio stays dark, a blown fuse is the most likely cause.
A rejected code on the Avenger's early Uconnect almost always means the wrong serial was submitted. The label has both a serial number (TM9 or T00AM, 14 characters) and a part number (P05064... or 68...) — submit only the serial.
Look at the sticker again and contact support for a free re-check if needed.
The Avenger's early Uconnect radio requires physical removal to access the serial label. On the label:
- Serial number — 14 characters, starts with
TM9orT00AM. Use this. - Part number — prefixed by
P05064or68. Not needed.
Copy all 14 characters carefully — similar-looking characters are easy to mix up on printed labels.
After three wrong codes on the Avenger's MyGIG, a 60-minute lockout activates. The display will present "WAIT":
- Leave the radio powered — key must stay in ON, engine off is fine.
- Allow the full 60 minutes.
- Cycling the ignition resets the timer.
Once clear, re-enter carefully.
How you enter the code on the Avenger depends on which radio is fitted:
- Touchscreen models (MyGIG REP 430, RBZ, RER 730N) — Use the on-screen number pad. The display accepts each digit.
- Non-touchscreen models (RES 130, REF) — Press preset button 1 cycling to set the first digit, button 2 for the second, 3 for the third, 4 for the fourth. Press and hold Enter/OK to submit.
If unsure which type you have: a glass you can tap means touchscreen entry; a non-touch face means preset buttons.
