Steps to Unlock Your 2020 Honda Accord Radio
To get the code, you'll take only 4 easy steps.
- Find your radio's serial number - this is the only information required by our side.
Unlike when contacting the dealer, no VIN is needed. - When you've found the S/N, type it into the form above.
The system checks it against a database of supported units and automatically retrieves the matching security code. - In most cases, the code will appear instantly on the screen after you pay and is also sent to your email for backup.
If we need to check it manually, you'll be notified before checkout. - When you receive it, just enter it into the radio to restore full functionality.
Code Entry Instructions
Now that you've generated 2020 Honda Accord anti-theft code from the serial number, you're ready to reactivate the radio.
Many drivers hesitate at this stage because input process can look different across radio versions, but it's usually easy.
When the radio shows ENTER CODE, it means the unit is waiting for the correct numbers.
Step-by-Step - The Correct Way to Enter It
To input the code on the 2020 Honda Accord:
- Ignition ON. Radio displays "CODE" or "ENTER CODE".
- Non-touchscreen models: Use preset buttons 1-5 to cycle to each digit, then press and hold button 6 to confirm.
- Display Audio touchscreen: An on-screen keypad is displayed. Enter each digit and press "Enter" or "OK".
Lockout: 3 wrong entries trigger a 60-minute lockout. Leave ignition ON. Do not cycle the key or the timer starts over.
Entering the 2020 Accord radio code
If the audio is locked you will see a CODE prompt on the Display Audio screen. The code is 5 digits long and is entered using the on-screen number keypad or the preset buttons 1-6 along the radio bezel (preset 1 enters 1, preset 2 enters 2, and so on). Enter each digit in order; a confirmation beep plays as soon as the radio unlocks.
How to Find the Serial Number on Your 2020 Honda Accord Radio?
The initial step is writing down the radio S/N.
Many people assume the code depends on the Honda model or year, but actually, the whole process relies on the unique radio's serial number.
The serial is the key used to calculate the correct unlock code.
This is even better, because if you have bought a used radio, the VIN or other Honda-specific data wouldn't help.
Based on the radio used, you may be able to see the serial directly from the display or by looking at the label on the radio chassis.
2020 Honda Accord factory radios
The 2020 Accord continued the 10th-generation Display Audio lineup. Honda made minor running changes - including expanded wireless connectivity in some software builds - but the radio hardware stays consistent.
The 7-inch Display Audio is standard on LX and Sport trims, while the 8-inch Display Audio with Honda Satellite-Linked Navigation is fitted to Touring and Hybrid Touring. EX, EX-L and Sport SE variants slot between with Display Audio plus premium audio packages where applicable.
All trims include Apple CarPlay, Android Auto, Bluetooth, HD Radio and SiriusXM. Premium audio trims use a 10-speaker, 450-watt system; mid trims use 8 speakers; LX uses 4 speakers. The receiver is fully integrated into the dash display module, so any battery disconnect can trigger the anti-theft code prompt that requires the original 5-digit code to clear.
View Your Serial on the Radio Display
These are the steps you should follow for 2020 Honda Accord:
The 2020 Honda Accord may feature Honda's Display Audio touchscreen (8" depending on trim) or a standard non-touchscreen radio. Either type support serial number display via the 1+6 button method:
- Turn ignition to ON. Wait for the radio to turn on. The screen shows "CODE" when anti-theft is active.
- Press and hold preset buttons 1 and 6 for approximately 3-5 seconds.
- The serial number displays in two halves (e.g.,
U3210+L0482).
Also: On 2020 Accord with the Display Audio touchscreen, look in Settings → System → Device Information – the serial may be shown there instead of the button combination.
Check it by Pulling Out the Radio Unit
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 housing.
Step-by-Step Approach:
- Turn off the vehicle.
- Remove the trim surrounding the radio.
- Release the clips.
- Pull the unit slightly out to access the label.
The serial number is usually located near the barcode.
If none of these methods succeed on the 2020 Honda Accord:
- Turn off the vehicle.
- Pry off the radio surround. The 2020 Accord's integrated dashboard uses snap-fit clips.
- On touchscreen trims: Remove the fasteners (Phillips-head) securing the screen unit.
- For standard radios: Remove the 4 Phillips screws holding the radio unit.
- Ease the unit forward and locate the serial on the label on the unit casing.
Note: The Display Audio unit is larger and more tightly fitted than the standard radio. Take care when removing it.
2020 Honda Accord radio removal
Safety first. Always disconnect the negative battery terminal and wait at least three minutes before touching dash modules so the SRS / airbag system fully discharges. Use plastic trim tools to avoid breaking clips on the integrated dash.
Begin by prying out the ignition / push-button start surround and disconnecting its harness. Open the glove box and remove the upper glove box trim (around ten clips). Pop off the passenger-side dash end cap, then pull the passenger-side HVAC vent assembly rearward to release its retaining clips. Working from the driver-side edge, pry off the climate control panel - approximately nineteen clips - and disconnect its harness and HVAC hose. With the climate panel out, remove the two Phillips screws holding the dash display module, lift the assembly, disconnect the data and power harnesses, and remove the unit. Reverse the process to reinstall, taking care that all clips fully seat to avoid dash rattles.

Common S/N Formats Used on 2020 Accord Units
Depending on which radio fitted to the 2020 Honda Accord:
U1234L5678– Most common Honda OEM formatHBM####– Found on Display Audio and navigation units913A####– Some Alpine-manufactured units
The 2020 Accord may have: base CD radio (U/L format), Display Audio 5"/7" (HBM format), or navigation unit (HBM format). All use a 5-digit unlock code.
Important Make sure you read the serial number, not the part number (which starts with 39100, 39101, or similar Honda part coding).
2020 Accord radio serial format
Honda Display Audio units in the 2020 Accord typically expose an 8 to 10 character alphanumeric serial. The serial uses uppercase A-Z and digits 0-9 with no separators.
Fixing Common Code Entry Problems for 2020 Accord
The Display Audio era includes radios using multiple serial prefixes depending on which unit was fitted:
U####L####— base CD radio serial (10 characters, two halves).HBM####— Display Audio 5"/7" and navigation units.913A####— certain Alpine OEM units.
Part numbers on the same label start with 39100 or 39101 — do not submit these. When in doubt, use the Settings → Device Information menu or the 1+6 button method to display the serial directly from the unit.
Code entry depends on the specific radio in the Display Audio-era Accord:
- Non-touchscreen base radio: Press preset buttons 1–5 to cycle to each digit, then hold button 6 to confirm — same as older Honda platforms.
- Display Audio 5" or 7" touchscreen: An on-screen numeric keypad is shown when the code prompt is active. Enter the digits and press OK or Enter on screen.
Should the touch input not work, try the physical preset buttons — certain units support either input method. Make sure the screen is fully powered on before starting entry.
If the Display Audio screen powers on but shows the home screen without a "CODE" prompt, check the following:
- The radio may not be locked — certain battery changes don't trigger the lock if power was restored fast.
- On some Display Audio units, the code prompt shows only on the audio portion of the screen, not the navigation display — wait a moment after startup.
- Try the Settings → System → Device Information route; should the serial appear, the unit may still be functional without a code.
If none of these apply, a fuse check is the next step — a failed fuse will stop the radio from powering on at all.
The Display Audio platform applies the same three-try lockout as earlier Honda radios. Recovery steps:
- Leave the ignition in ON or ACC — avoid turning it off.
- Allow the full 60-minute period. The touchscreen might dim during this time — this is expected.
- After 60 minutes, the radio re-displays "CODE" and you can.
For touchscreen units, the lockout countdown runs in the background. Just leave the vehicle running or the ignition on ACC for the full hour.
For Display Audio-era Honda radios, a rejected code most often means the serial was misread. Both the button method and the settings menu can produce the correct serial — verify that the serial you submitted was read off the radio unit and not from the owner's card.
After one failed entry, stop and reach out before trying again — a second wrong attempt brings you closer to the 60-minute lockout. A no-charge serial reverification can be done on request.
Why Did the Radio Lock and Ask for a Code?
Honda's Display Audio system carries the same anti-theft architecture as earlier radios: losing battery power triggers a code request at next startup. Applies to both the base radio and the Display Audio touchscreen.
- Battery replacement — the most common trigger.
- Battery disconnect during repairs — any work that interrupts battery power will re-engage the lock.
- Completely dead battery — a fully discharged battery also triggers the request.
Note: a number of higher-end Display Audio models from this era do not use a traditional code-based lock — if the radio never prompted for a code after losing power, it could have a different anti-theft method tied to the vehicle VIN.
