Understanding the Radio Serial Number and How to Locate It on 2018 Renegade
The first step is to find and write down the radio's S/N.
Depending on the radio unit used in your 2018 Renegade, the serial can usually be found either through the screen menu or by checking the label on the radio itself.
Below are the most common methods to identify your S/N quickly.
Which Head Unit Is in Your 2018 Renegade?
The 2018 model year was the final one before the BU Renegade's mid-cycle facelift. The factory Uconnect lineup stayed broadly the same as earlier BU years, with three head units sharing a common dash bezel.
Factory head units for the 2018 Renegade
- Uconnect 3 - non-touch base radio on Sport and entry European trims, with AM/FM, USB, iPod and 3.5 mm aux inputs.
- Uconnect 5.0 (5.0BT) - 5-inch colour touchscreen with Bluetooth hands-free, audio streaming and voice command, common on Latitude and similar mid trims.
- Uconnect 6.5 / 6.5N - 6.5-inch touchscreen with Garmin-based navigation on higher trims and option packages, often paired with HD Radio in the US market.
Quick visual ID
- No touchscreen, just a small display and hard buttons - that is the Uconnect 3.
- 5-inch touchscreen without a native Nav tile - that is the Uconnect 5.0.
- Larger 6.5-inch touchscreen with a Nav tile and on-screen mapping - that is the Uconnect 6.5/6.5N.
Access the Serial Number on the Radio Display
Try the following for your 2018 Jeep Renegade:
The 2018 Jeep Renegade is equipped with the Uconnect 7.0" touchscreen (RA2.1). The 7" Uconnect has a Dealer Mode for serial number retrieval:
- Turn ignition to ACC or ON.
- Press and hold the Temperature Up and Temperature Down buttons simultaneously for about 5 seconds.
- The Engineering Menu opens on the 7" screen.
- Navigate to: System Info → Target Main Data → Serial Number.
Note: On the 7" Uconnect, the menu path is slightly different from the 8.4" version. Look for "Target Main Data" instead of "Radio Part Info".
Taking Out the Radio to See the S/N on the Tag
If the serial does not appear on screen, the next step is checking the radio itself.
Many Jeep radios require physical access to the serial tag attached to the unit.
Typical approach:
- Start by completely powering down the engine - pull the key out.
- Then lift the dashboard bezel.
- Next, release the mounting points and slide the radio forward.
- Look for a printed tag showing the serial number.
If Engineering Mode fails on your 2018 Jeep Renegade, extract the radio to find the serial label:
- Turn off the vehicle.
- Pry off the dashboard bezel around the 7" screen. A trim removal tool to avoid scratching.
- Unscrew the 4 mounting screws (Phillips).
- Ease the radio forward to see the serial label on the chassis.
The 2018 Renegade's center stack is compact. Take your time when prying off the trim to avoid cracking the fasteners.
Manufacturer Label Inspection
If the on-screen approach is not available, or the radio is locked at the CODE prompt and the touchscreen is unresponsive, pulling the head unit out is the most dependable way to read the serial number on a 2018 Renegade. The bezel is retained by spring clips and the radio by four Torx screws, so the work is mechanically straightforward but worth doing with care.
Safety preparation
- Turn the ignition fully off and remove the key fob from the cabin.
- Disconnect the negative terminal of the 12V battery.
- Wait several minutes before reaching behind the dash so any airbag circuits can fully discharge.
- Avoid pulling on yellow airbag wiring as you remove trim.
Tools to have ready
- Plastic trim/panel pry tools to free the bezel without leaving marks.
- A Torx T-25 driver for the four radio retaining screws on the BU Renegade.
- A phone or camera to photograph the chassis label clearly.
Removal overview
- Use a panel tool to pry off the radio trim panel - it is held by around eight retaining clips around its perimeter.
- Walk the tool around the bezel until each clip releases.
- If the bezel carries any switches or HVAC controls, unplug their wiring before lifting it away fully.
- Undo the four T-25 Torx screws that secure the head unit to the dash frame.
- Slide the radio out and disconnect the wiring harness and antenna lead from the rear of the unit.
Where the serial sits
- Look for a printed label on the metal chassis - usually on the top or one side face.
- Copy the long alphanumeric string next to the barcode; that is the serial line.
Tips
- Photograph the label so the serial is preserved as a permanent reference.
- Reassembly is the reverse of removal: harness back on, four Torx screws home, bezel pressed in until each clip seats, then reconnect the battery.

Common S/N Formats Used on 2018 Renegade Units
The 2018 Jeep Renegade with Uconnect 7.0" features:
T00AM– Primary Harman prefixT00BE– Continental variant
Radio designation: RA2.1 (Uconnect 7.0" touchscreen). The Renegade shares the same radio platform with other Stellantis compact vehicles. Serial: 14 characters, alphanumeric.
S/N format is the same across all Uconnect screen sizes – only the Dealer Mode access method differs.
S/N Patterns and Prefixes
The 2018 Renegade was still being built at Melfi with a European supplier mix, so serial-number styles can differ slightly from US-market Mopar radios. The patterns below are the ones most commonly reported for this generation.
Renegade Uconnect prefixes
- Renegade Uconnect serial numbers typically start with the letter
T. - Prefixes seen across the Renegade range include
T0,TC,TQ,TZ,TB,TH,TM9andTVP. - The full serial is usually a 14-character alphanumeric string printed inline with the rest of the serial on the chassis label.
What to copy from the label
- Take the longest alphanumeric string next to the barcode - that is the serial line, not the part number.
- Double-check ambiguous characters such as O vs 0 and I vs 1 by comparing the printed string with the barcode.
If the alphanumeric you read does not match any of the patterns above, recheck that you copied the serial line rather than the part number. The serial is normally the longest string on the label and is the one tied to the barcode.
Code Entry Process for 2018 Renegade
After generating the correct unlock code based on the serial number, you can restore normal functionality by entering it into the unit.
The code entry process depends on the radio interface, but most 2018 Renegade 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 ENTER CODE displayed on screen.
Detailed Entering Instructions for Renegade 2018
To enter the code on your 2018 Jeep Renegade's Uconnect 7.0":
- Ignition ON. Screen shows "ENTER CODE" or ----.
- Tap the touchscreen keypad to enter each digit of the 4-digit code.
- The radio unlocks automatically after entering the 4th digit.
Lockout: 3 wrong attempts = 60-minute lockout. Keep ignition ON. Avoid turning off the ignition during the lockout period.
Detailed Input Instructions for Renegade 2018
Once you have the correct anti-theft code for your 2018 Renegade radio, the entry is fast - but the radio will lock you out for half an hour if you guess wrong too many times, so confirm the code before you start.
Limited Attempt Warning
Three attempts is the limit. After three successive wrong codes the radio enters a WAIT state and the display reads WAIT. To clear it, the radio must remain powered with the ignition in RUN for a continuous 30 minutes (the vehicle may be driven during this time). Switching the key off does not bypass the timer.
Entering the code
- Turn the ignition to RUN or ACC so the radio powers up and shows the CODE / Anti-Theft prompt.
- On the Uconnect 5.0 and Uconnect 6.5/6.5N touchscreens, tap each digit on the on-screen number pad.
- On the non-touch Uconnect 3 base radio, enter the digits with presets 1 to 4 - press preset 1 until the first digit shows, preset 2 until the second digit shows, preset 3 until the third digit shows and preset 4 until the fourth digit shows.
- Confirm with the OK/Enter on-screen control or the equivalent hardware button.
- When accepted, the radio returns to its normal home screen and audio resumes.
If it does not unlock
- Stop after the second wrong attempt and re-verify the serial used to obtain the code.
- Make sure no leading letters or trailing digits were dropped from the serial.
- If
WAITappears on screen, leave the radio powered for the full 30 minutes before trying again.
Unlock Your 2018 Jeep Renegade Radio in Minutes - How It Works
- Instead of contacting Jeep dealer or searching forums you can retrieve the code online using the radio S/N.
- Identify your radio's serial. It is always present on the unit itself, and sometimes it can be visible on the Renegade's radio screen.
- Enter it into the form above, and the software will generate the correct 2018 Renegade unlock code.
- After receiving your code, input it using Renegade's radio buttons to unlock the system fully.
- The entire process takes only a few minutes and requires no VIN, documents, or technical knowledge.
Why Is the Radio Asking for a Code?
The 2018 Renegade encounters radio lockouts most commonly from:
- Battery disconnect or replacement — the most frequent reason on all Uconnect platforms, including the 7" system.
- Dead battery from urban use — compact crossovers with frequent short trips can experience battery drain from short-trip driving patterns, triggering the lock.
- Blown fuse — a blown radio fuse cuts the radio supply and triggers the anti-theft lock.
- Used purchase — common in the used car market, and the code is often missing at resale.
The unlock code is permanently linked to the radio serial and does not expire.
Fixing Common Code Entry Problems for 2018 Renegade
The Uconnect 7.0" (RA2.1) uses the touchscreen exclusively for code entry — no hardware number buttons are used in the process. When the code entry prompt is on screen:
- Touch each digit on the on-screen keypad.
- The radio auto-confirms after the 4th digit — no submit step is needed.
Note that the Engineering Menu (Temperature Up + Temperature Down hold) is for serial retrieval only — this is not how you enter the code.
After 3 wrong attempts on the 7" Uconnect activate a 60-minute lockout. The screen shows "WAIT" or ceases accepting input. To handle the lockout:
- Leave the ignition ON for the entire 60 minutes.
- Turning off the ignition at any point restarts the 60-minute wait.
This lockout behavior is identical to the 8.4" Uconnect. Do not rush — the timer only counts while ignition is ON.
If the code does not work on the Uconnect 7.0" typically indicates the wrong serial was submitted. The 7" (RA2.1) serial is 14 characters, starting with T00AM or T00BE. The part number (P... or 68...) also appears on the label but generates no code.
Dealer Mode is the cleanest way to verify the serial on these models before submitting. Reach out for a free re-check if the code fails.
If the 7" Uconnect does not show after a battery event:
- Confirm the ignition is fully ON and allow 15–20 seconds for the RA2.1 system to boot.
- Inspect the radio fuse — a blown fuse prevents the radio from powering up.
- On the Renegade and Compass, the temperature button combo is separate from the code prompt — the prompt appears when the radio starts normally after a power loss.
Should the screen remain dark, check the fuse before anything else.
The RA2.1 system on the 2018 Jeep Renegade includes on-screen serial retrieval via the Engineering Menu: hold Temperature Up + Temperature Down for 5 seconds, then go to System Info → Target Main Data → Serial Number.
- Serial number — 14 characters, prefixed by
T00AMorT00BE. Submit this. - Part number — begins with
Por68. Not the serial.
On this system, the menu path says "Target Main Data" rather than "Radio Part Info" — that is normal for this system, not an error.
