Finding the Radio S/N for Chrysler
The first part is to find the radio's serial number.
Depending on the radio unit fitted in your 2023 Pacifica, the serial can usually be accessed either through the display menu or by checking the label on the radio itself.
Below are the most common methods to identify your serial the right way.
Factory Radios on the 2023 Chrysler Pacifica
The 2023 Pacifica continues the refreshed RU generation with Uconnect 5 hardware standard across the lineup. The 10.1-inch landscape touchscreen and the underlying UBN module carry over from 2022 with FOTA software updates layered on top.
- Uconnect 5 with 10.1-inch touchscreen (standard across the lineup). A landscape colour touchscreen mounted high on the redesigned centre stack, billed as the largest-in-class infotainment display on a minivan. Uconnect 5 is built on an Android-based platform, supports up to five user profiles, wireless Apple CarPlay and wireless Android Auto, and over-the-air software updates - the 2023 UBN module continues to receive 4G FOTA firmware updates as documented in retrofit threads.
- Audio system pairings. The factory audio package layered on top of the Uconnect 5 head unit varies by trim - a 6-speaker base system on lower trims, a 13-speaker Alpine premium system on mid trims and a 20-speaker Harman Kardon system with a 760 W amplifier on Limited and Pinnacle. The audio system does not change which Uconnect 5 head unit you have, only the amplifier and speaker package behind it.
- Optional Uconnect Theater rear-seat entertainment. A separate option that adds two seatback-mounted screens for second-row passengers along with HDMI input, wireless headphones and Amazon Fire TV streaming integration. These rear screens are tied to their own controller and are not the same module as the Uconnect 5 head unit at the front.
- Hybrid-specific Uconnect pages. Pacifica Hybrid models continue to add EV-specific Uconnect 5 pages - charging schedule, energy flow and hybrid-electric data - layered on the same 10.1-inch head unit rather than as a separate radio.
View Your Serial Number via the Radio Screen
Try the following for your 2023 Chrysler Pacifica:
The 2023 Chrysler Pacifica — including the Pacifica Hybrid PHEV variant — is equipped with the Uconnect 4C (RA4) on the updated platform. Press the bottom-left and bottom-right corners of the physical bezel frame simultaneously for 5 seconds (ignition ACC or ON) to open Dealer Mode. Navigate to: System Info → Radio Part Info → Serial Number.
Keep in mind: press the plastic bezel frame, not the touchscreen itself.
Pacifica's Hardware Label Method
If the serial does not appear on screen, the next step is checking the radio itself.
Many Chrysler radios require physical access to the serial sticker attached to the unit.
Common approach:
- Start by completely turning off the engine - pull the key out.
- Then detach the trim panel.
- Next, release the mounting points and slide the radio forward.
- Look for a printed tag showing the serial number.
If Dealer Mode is unavailable on the 2023 Chrysler Pacifica Pacifica, remove the RA4 unit from the minivan's elevated center stack.
- Pry off the bezel panel with a plastic trim tool.
- Remove the 4 Phillips mounting screws.
- Slide the unit forward to read the serial label.
Note: the Pacifica's high-mounted screen position may differ slightly from older Chrysler minivans.
Releasing the Unit to Access the S/N on the Tag
The 2023 Pacifica head unit shares the refreshed centre stack of the 2021-2024 generation - the 10.1-inch Uconnect 5 display is integrated with the climate controls and sits behind a layered receiver trim panel. Forum DIY writeups for the 2021-2024 UBN module note that the unit is wired into the vehicle data bus, so dropping it out is meaningfully more involved than on a pre-refresh Pacifica.
Recommendation: have the unit pulled by a Chrysler dealer or a trim/audio specialist. If the radio is already being removed for service or warranty work, ask the technician to photograph the chassis label so the serial number can be transcribed accurately.
- Safety first. If any DIY work is unavoidable, switch the ignition off, remove the key fob from the cabin, disconnect the negative battery terminal and wait several minutes before touching any harness; never disturb yellow airbag/SRS connectors and only use plastic trim tools so the centre-stack clips and surrounding bezels stay intact.
- Tools you would need. A full plastic trim removal kit, a 7 mm socket with ratchet and extension, a Phillips screwdriver, a small Torx bit set and a good flashlight; pacificaforums.com installation threads describe removing several screws between the A/C console and the radio surround before prying the trim free.
- Removal overview (information only). The receiver trim panel is unclipped at the bottom edge with a plastic tool to release the retaining clips; the small fasteners between the climate console and the radio surround are removed first to relieve tension. Behind the trim sit screws holding the screen/receiver assembly to the dash. With those out, the assembly comes forward and the multi-pin harnesses on the rear of the unit are unplugged.
- Where the serial sits. On Uconnect 5 hardware the radio serial number is printed on a thermal/barcode label on the back or top of the chassis, next to the Mopar part number and supplier markings.
- Tips. Photograph the label in good light, copy each character exactly and double-check ambiguous characters such as 0/O, 1/I and B/8 before submitting the serial.

Standard Serial Number Patterns on This Radio
The 2023 Pacifica ships exclusively with the Uconnect 5 10.1-inch head unit (UBN platform) across the lineup. Stellantis sources Uconnect 5 modules from more than one supplier, and the prefix on the chassis label varies with which supplier built the unit, so the only authoritative reference is the printed sticker on the radio itself.
Uconnect 5 (10.1" UBN)
- The serial is typically a continuous alphanumeric block printed on a thermal/barcode label on the chassis, with no dashes or spaces.
- Newer Stellantis Uconnect 5 head units have been observed using
T-style prefixes such asT0071andT00AD, but a comprehensive 2023-specific prefix list is not publicly published. - Treat the printed label on the unit itself as authoritative and copy each character exactly - do not infer the prefix from the trim level or audio package.
How to Unlock a Chrysler Pacifica Radio After Power Loss
- Rather than relying on Chrysler dealership lookup or online threads you can generate the code online using the radio S/N.
- Identify the serial number. The best place to search is on the unit itself, and in some cases it can be visible on the Pacifica's radio screen.
- Type it into the field above, and the software will generate the correct 2023 Pacifica unlock code.
- When you receive the code, input it using Pacifica's radio controls to release the blockade successfully.
- The entire process takes less than a minute for most users and requires no VIN, documents, or technical knowledge.
How to Enter the Radio Code
Once you have the S/N and generated the unlock code, the final part is entering it into your radio.
Chrysler original head units display a CODE prompt when ready for input.
The process is quick, but button layouts and confirmation methods may vary depending on the radio version installed in your Pacifica.
Entering Process
To enter the code on the 2023 Chrysler Pacifica Uconnect 4C:
- Turn ignition to ON. Screen shows "ENTER CODE".
- Enter each digit of your 4-digit code on the touchscreen keypad.
- Radio unlocks after the 4th digit. No confirm button needed.
3 wrong attempts cause a 60-minute lockout. Keep ignition ON. Switching off restarts the timer.

What Caused the Radio to Lock?
The 2023 Chrysler Pacifica radio self-locks after power is cut. Pacifica Hybrid owners may encounter this after high-voltage system work that involves disconnecting the 12V auxiliary battery.
Most common trigger: battery replacement or disconnect. Other causes:
- Blown radio fuse
- Buying the Pacifica used without a code
- Battery disconnect for service
- Battery drained from sitting unused
Code comes from the radio serial number — not the VIN.
