How to Find the Serial Number on Your 2024 Honda Accord Radio?
The first step is to locate the radio's serial number.
Based on the head unit type fitted in your 2024 Accord, the S/N can usually be found either through the display menu or by checking the label on the radio itself.
Below are the most common methods to identify your S/N the right way.
Factory Radios on the 2024 Accord
The 2024 Accord carries the 11th-generation infotainment line-up forward unchanged - two distinct factory head units, split along the same gas-vs-hybrid line as 2023. Identifying yours is the first step before any code-retrieval work.
7-inch Display Audio (LX, EX gas trims). Visual ID: a 7-inch landscape touchscreen in the centre dashboard. Wired Apple CarPlay and wired Android Auto are standard, along with Bluetooth, AM/FM, two USB ports and HondaLink. The LX has a 4-speaker, 160-watt audio system; the EX upgrades the speakers to eight (180 watts), but the head unit itself is the same 7-inch hardware on both trims.
12.3-inch Touchscreen with Google built-in (Sport Hybrid, EX-L Hybrid, Sport-L Hybrid, Touring Hybrid). Visual ID: a much larger 12.3-inch landscape touchscreen with native Google services on the Touring Hybrid - 'Hey Google' voice control, Google Maps as the native navigation app, and Google Play for third-party audio apps such as Spotify, iHeartRadio, NPR One and audiobook players. Wireless Apple CarPlay and wireless Android Auto are standard. The Touring Hybrid pairs this head unit with a 12-speaker Bose premium audio system; lower Hybrid trims keep the 12.3-inch head unit with smaller speaker counts.
For code retrieval purposes, every 2024 Accord falls into one of these two head-unit families. Audio packages and powertrain choices change the speakers, amplifier and on-screen apps but do not change which physical head-unit module is in the dash.
Using Hidden Radio Menus to Find the Serial
Try the following for your 2024 Honda Accord:
The 2024 Honda Accord features Honda's current-generation infotainment system with a 9" touchscreen. The serial number is accessible through the infotainment menu:
- Turn ignition to ON.
- Navigate to: Settings → System → Device Information or System Information.
- The serial number should be shown on this screen.
Alternative: The traditional buttons 1+6 method may also work if the menu method fails to reveal the serial. Hold buttons 1 and 6 for about 5 seconds while the radio shows "CODE".
Pulling Out the Unit to See the S/N on the Tag
If the serial number cannot be accessed via display, use the removal method.
Most Honda Accord factory radios include a tag with the serial number printed on the casing.
The process:
- Remove key from ignition.
- Carefully remove surrounding dashboard trim.
- Loosen screws holding the radio.
- Pull forward to inspect the label.
If menu access fail on the 2024 Honda Accord:
- Power down the vehicle.
- Detach the center stack trim around the touchscreen. Modern Honda vehicles use integrated trim with plastic retainers.
- Unscrew the mounting screws securing the infotainment unit.
- Ease the unit out to view the serial label on the side of the module.
Caution: Newer Honda infotainment units are closely integrated into the dashboard. Try the software-based method first.
Pulling Out the Radio Unit to See the S/N on the Tag
The 2024 Honda Accord shares the same 11th-generation integrated centre dashboard used since launch, with the 7-inch Display Audio or 12.3-inch Google-built-in screen mounted into a moulded centre stack alongside the climate controls and a paired digital instrument cluster. A clean public DIY removal procedure for this head unit is not yet documented in service manuals or trusted Honda forums.
The centre dash carries airbag wiring (passenger airbag and side curtain harness), the climate control module, USB-C ports and the digital cluster harness, all of which sit close to the head unit and can be damaged or trigger warning lights if the trim is removed without the correct order of steps. On Hybrid trims the 12.3-inch Google-built-in unit also runs paired authentication tied to the VIN, so a careless disconnection can leave the unit in a 'not paired' state that only a dealer can resolve.
For these reasons we recommend handing the physical removal to a Honda dealer technician or to an experienced car-audio installer with 11th-gen Accord experience, rather than attempting a blind teardown. The serial number sticker is on the top or side of the metal radio chassis once the unit is unbolted from the dash.
A Honda dealer can usually read the radio serial number directly through their HDS (Honda Diagnostic System) tool on the OBD-II port without removing the unit at all - this is normally the fastest and lowest-risk path on a near-new car under warranty. If the dealer cannot help, an audio specialist with the right trim removal tools is the next-best option.
Before booking an appointment, check the obvious places first: the owner's manual pouch, the glovebox, the original window sticker and any paperwork delivered with the car. Honda dealers commonly place a small white label with the radio anti-theft code in the glovebox or owner's manual wallet at delivery, which avoids the service visit entirely.

What a Valid Serial Number Looks Like
The 2024 Honda Accord uses Honda's newest infotainment system. Serial number formats:
HBM####– Most common format for newer Honda Display Audio unitsU1234L5678– May still appear on certain base radio configurations
The 2024 Accord's infotainment is made by Honda's OEM partners (Alpine). The serial is usually 8 to 10 characters long.
Note Certain 2024+ Accord trims may use Google-based infotainment that might not need a traditional radio code. If your radio doesn't show "CODE" after a battery disconnect, it may no longer be code-locked.
Code Entry Instructions
After locating the serial number and generated the unlock code, the final step is entering it into your radio.
Honda OEM units display a ENTER CODE message when ready for input.
The process is simple, but button layouts and confirmation methods may change depending on the radio version installed in your Accord.
Detailed Input Instructions for Accord 2024
To input the code on the 2024 Honda Accord:
- Ignition ON. The display shows "CODE" or "ENTER CODE".
- When an on-screen keypad is displayed: Enter each digit and press Enter.
- If the radio has preset buttons: Use buttons 1-5 to select each digit of the 5-digit code, then press and hold button 6 to confirm.
Lockout: 3 incorrect entries = 60-minute lockout. Ignition must remain ON for the full period.
Step-by-Step Honda Accord 2024 Radio Code Retrieval Guide
- Skip long troubleshooting discussions or service visits - you can find the code online with the radio S/N.
- Identify the serial number. The best place to search is on the unit itself, and sometimes it can be visible on the Accord's display.
- Enter it into the generator above, and our system will calculate the correct 2024 Accord unlock code.
- After getting it, input it using Accord's radio buttons to release the blockade fully.
- The entire process takes less than a minute for most users and requires minimal effort.
Fixing Common Code Entry Problems for 2024 Accord
On modern Honda infotainment, code entry is typically done via the on-screen keypad:
- Enter each digit of the five-digit code using the on-screen number pad.
- Press OK or Enter to submit the full code.
On models where hardware preset buttons are still present, use buttons 1–5 for digit selection and hold button 6 to confirm — identical to older Honda platforms. If unsure which method applies, try the touchscreen first.
With the latest Honda system, a rejected code usually comes down to the wrong serial being submitted. The serial can be found through Settings → Device Information — confirm that the serial you used is the same as what appears there.
Some newer Accord trims have switched to Google-based infotainment which doesn't use a traditional radio code. Should the unit never showed "CODE", a traditional code may not apply. Contact support to clarify which system is fitted.
When the newer system boots but never shows a "CODE" prompt, it is likely one of the following:
- Some trims skip the code lock — certain current-generation trims rely on VIN-linked security instead of a traditional code.
- The radio may already be unlocked — test normal radio operation first.
- Check the settings menu Settings → System → Device Information — if this menu opens normally, the system may not be in a locked state.
Should this not resolve the situation, the unit may need service — reach out to us with the vehicle details for guidance.
After three wrong code entries, the modern Honda infotainment triggers a 60-minute lockout. Recovery is straightforward:
- Leave ignition ON — do not switch off the vehicle.
- Wait for the full 60 minutes to elapse. The display may enter standby — that is normal.
- After the lockout period, the "CODE" prompt returns.
Should the car cannot idle for 60 minutes, ACC mode works too to keep the timer counting. Do not cutting power — it restarts the countdown.
Modern Honda infotainment typically uses the HBM#### serial format, though base radio configurations may still use the U####L#### format. The easiest way to confirm the serial is:
- Navigate to Settings → System → Device Information — the serial appears on this screen.
- As a fallback, use the 1+6 preset button method while the "CODE" screen is displayed.
The part number — which begin with 39100 — is printed nearby but should not be used as the serial. Submit only the serial from the menu or the button method.
Why Is the Radio Asking for a Code?
Even on Honda's most recent infotainment platform, the anti-theft code may trigger when the battery is replaced. The cause is the same across every Honda platform: loss of battery power wipes the radio's authorization state.
- Battery swap or disconnect — the primary trigger.
- Dead battery from storage or neglect — a fully discharged battery triggers the same lock.
Important caveat: a growing number of 2022+ Honda vehicles have moved to Android-based infotainment that does not use a traditional unlock code. If the unit showed no code request after a battery event, it may use VIN-based protection rather than a numeric code.
