What Caused the Radio to Lock?
The 2019 Compass (MP) sees radio lockouts primarily from:
- Battery disconnect or replacement — the primary cause on all Uconnect platforms.
- Dead battery from commuter use — Compass vehicles used as daily commuters may experience battery drain from high infotainment use on short journeys, triggering the lock.
- Used purchase — the redesigned Compass is a popular family-oriented used vehicle, and the code is often not included at resale.
- Blown fuse — fuse failure interrupts power and triggers the code lock.
The code is linked to the radio serial and never expires.
How to Find the Serial Number on Your 2019 Jeep Compass Radio?
The first part is to locate the radio's S/N.
Depending on the radio unit used in your 2019 Compass, the serial can 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.
Identify Your 2019 Compass's Factory Radio
For 2019 the Compass transitions from the RA family to the Uconnect 4 line-up. There are three factory head units on the trim ladder: one 7-inch UAG and two 8.4-inch variants that differ only in built-in navigation.
Uconnect 4 (UAG) is the 7-inch touchscreen, non-NAV. Standard on Latitude, Latitude Plus and Altitude. Visual ID: 7-inch display centred in the dash opening with bezel filling the surround; Apple CarPlay and Android Auto are supported, but there is no built-in NAV app and no Map tile on the home screen. Most common radio in this model year.
Uconnect 4C (UAS) is the 8.4-inch touchscreen, non-NAV. Optional on Latitude Plus and Limited, common on Trailhawk. Visual ID: large 8.4-inch screen filling the dash opening, CarPlay and Android Auto present, but no Map/NAV tile because navigation is not built in.
Uconnect 4C NAV (UAQ) is the 8.4-inch touchscreen with built-in GPS. Standard on Limited and the High Altitude package, often optioned on Trailhawk. Visual ID: identical 8.4-inch bezel and screen size to UAS, but the home screen carries a dedicated NAV/Map tile and on-board maps are bundled.
Telling UAS apart from UAQ is purely a software check - identical hardware face, but only UAQ shows a Map/NAV tile and on-board maps. Note: the Sport trim continues with a 5-inch Uconnect 3 base unit; this is not part of the Uconnect 4 family.
Fast Serial Lookup Using Radio Controls
Try the following for your 2019 Jeep Compass:
The 2019 Jeep Compass (MP platform, redesigned) features the Uconnect 7.0" touchscreen (RA2.1). The redesigned MP Compass features a more modern dashboard compared to the older MK49 platform, with the 7" screen sitting in a streamlined center stack. Retrieve the serial via Dealer Mode:
- Turn ignition to ACC or ON.
- Press and hold the Temperature Up and Temperature Down buttons simultaneously for approximately 5 seconds.
- The Engineering Menu opens on the 7" screen.
- Navigate to: System Info → Target Main Data → Serial Number.
Note: On the 7" Uconnect, navigate to "Target Main Data" rather than "Radio Part Info" — this is normal for the RA2.1.
Screen-Based Serial Lookup Method
The 2019 Compass ships with the Uconnect 4 family on most trims. On these units the radio serial number can usually be read straight from the touchscreen via the hidden dealer/diagnostic menu - no need to remove the unit from the dash.
Uconnect 4C 8.4 (UAQ / UAS)
Switch the ignition to RUN/ACC and wait for the Uconnect interface to finish booting. Press and hold the driver-side temperature UP, the driver-side temperature DOWN, and the front DEFROST buttons together for roughly 5-10 seconds. If the climate-button method does nothing, press and hold the bottom-left and bottom-right corners of the screen at the same time for about 5-10 seconds. Browse to the radio/system info section to read the serial number on screen, then photograph the screen so each character can be transcribed without typos.
Uconnect 4 7-inch (UAG)
Place the ignition in RUN/ACC and let the screen finish loading. Press and hold both temperature UP and temperature DOWN buttons together for around 5-10 seconds to enter the engineering menu, then open System Info / Target Main Data to view the serial number on screen. Snap a photo of the display so the digits can be copied accurately.
Pulling Out the Radio to See the S/N on the Tag
If the serial does not appear on display, the next step is checking the radio itself.
Many Jeep radios require physical access to the serial tag attached to the unit.
Usual approach:
- Start by completely shutting off the engine - pull the key out.
- Then lift the radio surround.
- Next, loosen the mounting points and move the radio forward.
- Look for a printed tag showing the serial number.
If Engineering Mode doesn't work on your 2019 Compass (MP), remove the radio to find the serial label:
- Turn off the vehicle.
- Pry off the bezel panel around the 7" screen. The MP Compass's modern trim has snap fasteners – use a plastic trim tool, starting at the bottom.
- Remove the 4 Phillips mounting bolts.
- Pull the unit out to read the serial label on the top or side of the chassis.
MP Compass Note: The redesigned Compass has a tighter center stack than the older MK49. Work carefully when prying the bezel to avoid breaking the narrow trim clips.
Compass's Hardware Label Method
If the on-screen menu is unavailable on the 2019 Compass - for example after a software update that disabled dealer mode - the chassis label can still be reached by carefully removing the head unit. The Uconnect 4 stack on the MP Compass sits inside a centre stack bezel with the climate cluster below, so work slowly to avoid breaking trim clips.
Safety first. Switch the ignition off, take out the key, disconnect the negative battery terminal, and wait a few minutes before touching wiring. Avoid the yellow airbag/SRS connectors entirely and use plastic trim tools so nothing shorts or breaks.
Tools you will need. Plastic trim removal kit, Phillips and small Torx bit set, 7mm/10mm socket set, flashlight.
Removal overview. Pry the centre stack bezel free with a plastic trim tool starting at the bottom edge and working up the sides; on the MP Compass the bezel sits next to the climate cluster, so keep pressure even. Unplug any switch/HVAC connectors at the rear of the bezel before laying it on a clean cloth. Remove the screws (typically four, two upper and two lower) holding the radio cage to the support bracket, slide the radio rearward, and disconnect the antenna lead and the multi-pin power/data harness on the back.
Where the serial sits. The serial number is printed on a barcode/sticker label on the top or side of the radio chassis, alongside the part number and supplier markings.
Tips. Photograph the label up close and double-check ambiguous characters such as 0/O, 1/I and B/8 before submitting the serial. If working around airbag wiring is uncomfortable, have a professional installer take the unit out for you.

Typical Serial Number Formats for 2019 Compass Radios
The 2019 Compass (MP) with Uconnect 7.0" serial formats:
T00AM– Primary Harman prefixT00BE– Continental variantT0MYD– Newer Harman production (later Compass)
Radio designation: RA2.1 (Uconnect 7.0"). Serial: 14 characters, alphanumeric. The serial format is identical across all Uconnect variants.
Standard Serial Number Patterns on This Radio
The factory radios on the 2019 Compass follow the standard Mopar/Uconnect serial style, with the prefix depending on the Uconnect tier and the supplier (Visteon, Continental, Harman or Panasonic) that built the unit.
Uconnect 4C 8.4 (UAQ / UAS)
The serial is typically a 14-character alphanumeric string printed on the chassis label. It commonly begins with T - frequent prefixes include T00AM, TM9 and TQ1 - or with A2C on Continental-built variants. The serial is usually a continuous run of letters and digits with no dashes or spaces.
Uconnect 4 7-inch (UAG)
The 7-inch UAG unit usually carries a Mopar/Harman or Panasonic-style serial printed on the chassis sticker, so the label on the unit itself is the authoritative reference. Always copy the serial exactly as printed and avoid guessing characters that look unclear.
Unlock Your 2019 Jeep Compass Radio in Minutes - How It Works
To get the code, you'll take only a few easy steps.
- Locate the radio's serial - this is the only info required to generate the correct unlock code.
The difference with the dealership lookup is that no VIN is needed. - Enter the serial number into our generator above.
The system checks it against a database of supported factory radios and automatically finds the matching anti-theft code. - In most cases, the code appears instantly on the screen after you pay and is also sent to your email , just in case.
If manual verification is required (rare situations), you'll be notified before checkout. - Once you receive it, simply enter it into the radio to restore full functionality.
Unlocking the Radio After Code Generation
Now that you've found the S/N and received the unlock code, the next step is entering it into your radio.
Jeep original head units display a locked screen when ready for input.
The process is straightforward, but button layouts and confirmation methods may vary depending on the radio version installed in your Compass.
Detailed Input Instructions for Compass 2019
To enter the code on your 2019 Compass (MP)'s Uconnect 7.0":
- Ignition ON. Screen displays "ENTER CODE" or ----.
- Use the touchscreen keypad to enter each digit of the 4-digit code.
- Radio auto-confirms after entering the 4th digit.
Lockout: 3 wrong attempts = 60-minute lockout. Keep ignition ON. Cycling the ignition resets the timer.
Correct Entering Process
Once the unlock code is in hand, the 2019 Compass Uconnect head unit can be unlocked directly at the dash - no scan tool or dealer visit required.
Limited attempts. Mopar/Uconnect head units only accept three incorrect tries before the radio drops into a WAIT state, so verify every digit before pressing it.
Entering the code. Place the ignition in RUN/ACC so the radio powers up but the engine stays off. Wait for the display to show CODE, Please enter Anti-Theft Code, or a similar prompt. On the Uconnect 4C 8.4 (UAQ/UAS), tap the on-screen number pad and confirm with the OK/Enter touch button. On the Uconnect 4 7-inch (UAG), use the on-screen keypad - or the numbered preset buttons if the unit prompts for them - to enter the code in sequence.
If a wrong code was entered. If WAIT appears after incorrect attempts, leave the radio powered with the ignition in RUN for the documented cool-down period (about 30 minutes; the vehicle may be driven during this time) before trying the correct code again.
Understanding Unlock Issues with Your Compass
The RA2.1 on the 2019 Compass (MP) supports 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 — 14 characters, starting with
T00AM,T00BE, orT0MYD. This is what to submit. - Part number — starts with
Por68. Do not use.
On the 7" Uconnect, the menu path says "Target Main Data" rather than "Radio Part Info" — this is correct.
If the code fails on the Compass MP's Uconnect 7.0" usually means a serial number mismatch. The RA2.1 serial is 14 characters, starting with T00AM, T00BE, or T0MYD. The part number (P... or 68...) is also shown on the label but generates no code.
The Engineering Menu is the recommended approach to confirm the serial on the Compass MP. Reach out for a free re-check if the code fails.
After 3 wrong attempts on the Compass MP's 7" Uconnect trigger a 60-minute lockout. The screen shows "WAIT". To handle the lockout: leave the ignition ON for the entire 60 minutes. Cycling the ignition resets the lockout timer.
The Compass MP's Uconnect 7.0" (RA2.1) uses touchscreen exclusively for code entry — no hardware buttons used. Touch each number on the on-screen keypad. Radio unlocks after the last digit.
The temperature button combo (Temp Up + Temp Down hold) is only used to find the serial — this is not the code entry method.
If no code entry screen appears after a power event: ensure ignition is ON and give 15–20 seconds for the RA2.1 system to boot. Inspect the fuse panel — a blown fuse prevents the radio from powering up.
