Where to Find the Serial Number on your Odyssey
The first step is finding the radio serial.
Most people assume the code depends on the Honda model or year, but actually, the unlock process relies on the unique radio's serial number.
Each radio has its own serial tied to the security system.
This is actually better, because if you have a used radio, the VIN or other vehicle-specific data wouldn't be of much use.
Depending on the radio used, you may be able to see the serial directly from the display or by checking the label on the radio chassis.
Factory radios fitted to the 2014 Honda Odyssey
- LX base receiver with AM/FM/CD playback driving 5 speakers, paired with the upper i-MID secondary information display; this trim retained the conventional button-and-knob fascia for 2014.
- EX, EX-L and Touring head unit, redesigned for the 2014 mid-cycle refresh with new touch-panel audio controls and Honda Display Audio (HDA) integration, supporting HondaLink-based smartphone features and the Pandora interface.
- EX-L and Touring with optional Honda Satellite-Linked Navigation System, adding a touchscreen navigation interface, voice recognition and Bluetooth HandsFreeLink on top of the HDA hardware.
- Touring Elite range-topping audio package, combining HDA, factory navigation, an upgraded Rear Entertainment System with widescreen video monitor and HDMI input, and a 650-watt 12-speaker premium audio system with HD Radio.
Screen-Based Serial Lookup Method
Try the following for your 2014 Honda Odyssey:
The 2014 Honda Odyssey may feature Honda's Display Audio system (5" depending on trim) or a base non-touchscreen radio. Both types support serial number retrieval via the 1+6 button method:
- Turn ignition to ON. Wait for the radio to power up. The screen shows "CODE" if locked.
- Hold down preset buttons 1 and 6 for about 5 seconds.
- The serial number appears in two halves (e.g.,
U3210+L0482).
Alternative: On 2014 Odyssey with the Display Audio touchscreen, navigate to Settings → System → Device Information – the serial may be listed there instead of the button combination.
Reading the serial on a 2014 Odyssey factory radio
- Make sure all doors are closed and the radio is currently powered off, then turn the ignition switch to the ON position so the dash is live but no audio is playing.
- Press and hold preset buttons 1 and 6 on the radio's preset row at the same time; on HDA units the touch-panel preset surfaces accept the same long-press input.
- While continuing to hold 1 and 6, press the radio power button or rotary so the unit boots into the service screen used to display the serial.
- Record the four digits shown after the letter U on the first screen; these are the upper half of the serial.
- Wait for the display to alternate to the L screen and record the next four digits shown after the letter L; these are the lower half.
- Concatenate the two halves into a single 8-character serial; the U and L are screen prefixes and are not part of the value submitted to Honda's lookup tools.
Releasing the Unit to See the S/N on the Tag
If the serial number cannot be accessed through menu, use the hardware method.
Most Honda Odyssey original radios include a label with the serial number printed on the casing.
Basic process:
- Shut down the car.
- Carefully remove surrounding panel pieces.
- Loosen screws holding the radio.
- Slide outward to inspect the label.
If none of these methods succeed on the 2014 Honda Odyssey:
- Power down the vehicle.
- Remove the dashboard trim. The 2014 Odyssey's integrated dashboard uses plastic clips.
- On touchscreen trims: Unscrew the mounting screws (Phillips-head) securing the display module.
- For standard radios: Remove the four screws holding the head unit.
- Slide the unit forward and locate the serial on the sticker on the chassis.
Note: The Display Audio unit is larger and more integrated than the base radio. Take care when removing it.
Removing the radio on a 2014 Odyssey to read the serial label
- Disconnect the negative battery terminal and wait several minutes for residual SRS power to drain before touching the refreshed centre stack.
- Use the shift-lock release to drop the gear selector into its lowest position, then pry up the gear-shift trim panel from its rear edge to release the clips, unplug any harnesses and lift the panel out.
- Open the glove box, pry out the rear edge of the dash end cap and remove the upper glove box trim panel by releasing its retaining clips so the centre stack is accessible from the passenger side.
- Remove the four 8 mm screws securing the climate control and centre vent trim, then pry the trim panel away to release its clips and disconnect the climate, audio and HDA touch-panel harnesses on the back.
- Take out the screws now visible on the receiver's mounting brackets, slide the head unit evenly out of the dash supporting it by the chassis rather than the touch panel face, and disconnect the antenna lead and multi-pin connectors on the back.
- Read or photograph the 8-character chassis label on the side of the radio; it should match the value reported by the on-screen procedure. Plastic trim tools should be used throughout to avoid marking the refreshed soft-touch dash plastics, and the harness routing should be preserved on reassembly.

S/N Patterns and Prefixes
Depending on which radio equipped in the 2014 Honda Odyssey:
U1234L5678– Most common Honda OEM formatHBM####– Found on Display Audio and navigation units913A####– Certain Alpine-manufactured radios
The 2014 Odyssey 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 Ensure you copy the serial number, not the part number (which starts with 39100, 39101, or similar Honda part coding).
What the 2014 Odyssey radio serial usually looks like
- The serial returned by the on-screen procedure is 8 characters long. On most 2014 Odyssey LX, EX and EX-L head units the value is purely numeric, although some chassis labels include letters or longer manufacturer prefixes that should be ignored.
- The U on the first screen and the L on the second screen are display labels for the upper and lower halves of the serial; they are not entered into Honda's lookup tools.
- A typical example documented on Honda dealer pages reads U2200 followed by L0055, which corresponds to a stored serial of 22000055.
- HDA-equipped EX, EX-L and Touring units, and the Touring Elite head unit, follow the same 8-character pattern and present the values on the touch-panel display.
Final Step - Enter the Radio Code
After generating the correct unlock code based on the S/N, you can restore default functionality by entering it into the unit.
The code entry process depends on the control layout, but most 2014 Odyssey 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 CODE displayed on screen.
Step-by-Step - The Correct Way to Enter It
To input the code on the 2014 Honda Odyssey:
- Ignition ON. Radio displays "CODE" or "ENTER CODE".
- Non-touchscreen models: Press preset buttons 1-5 to select each digit, then hold button 6 to confirm.
- Display Audio touchscreen: An on-screen keypad is displayed. Tap each digit and press "Enter" or "OK".
Lockout: Three wrong codes trigger a 60-minute lockout. Keep ignition ON. Do not cycle the key or the timer resets.
Entering the unlock code on a 2014 Odyssey radio
- Turn the ignition to ON and power the radio so that CODE or ENTER CODE appears on the display.
- Enter each of the five digits in order with a single press of the same-numbered preset; on HDA units the touch-panel presets accept the same input.
- On Touring, Touring Elite or any HDA unit fitted with the optional navigation, the digit can also be set by rotating the selector knob and confirmed using the right-arrow soft key on the touchscreen.
- No hold on preset 6 is needed: the code is normally accepted after the fifth digit. Touchscreen units may show an ENTER soft key to tap.
- The radio should resume normal operation immediately if the code is correct; if it is wrong, repeat the process carefully because each wrong attempt counts toward the lockout limit.
- After approximately ten incorrect entries the unit enters a temporary lockout that requires the ignition to be left in the ON position for about an hour before another attempt is accepted.
From Serial Number to Unlock Code for your Honda Odyssey - Explained
- Rather than relying on Honda dealership lookup or online threads 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 you can see it on the Odyssey's display.
- Type it into the form above, and our software will calculate the correct 2014 Odyssey unlock code.
- After receiving your code, input it using Odyssey's radio controls to unlock the system successfully.
- The entire process takes less than a minute for most users and requires zero paperwork and no dealer visit.
Fixing Common Code Entry Problems for 2014 Odyssey
The Display Audio platform enforces the same 3-attempt lockout as earlier Honda radios. Recovery steps:
- Leave the ignition in ON or ACC — do not switch off.
- Allow the full 60-minute period. The touchscreen might dim during this time — this is expected.
- After 60 minutes, the code prompt returns and you can.
On Display Audio touchscreen models, the lockout countdown runs in the background. Simply leave the vehicle running or the ignition on ACC until the timer expires.
When the touchscreen powers on but shows the home screen without a "CODE" prompt, consider these points:
- Anti-theft may not have triggered — certain battery changes skip the lock if power was restored fast.
- Certain 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; if the serial is visible there, the unit may still be functional without a code.
If none of these apply, a fuse check is the next step — a blown fuse prevents the radio from showing any display at all.
For Display Audio-era Honda radios, a rejected code usually points to the serial was taken from the wrong source. Either retrieval method can produce the correct serial — confirm that the serial you submitted came from the radio itself and not from a sticker elsewhere in the car.
After one failed entry, stop and reach out before trying again — a second wrong attempt gets you one step closer to the 60-minute lockout. A no-charge serial reverification is available on request.
The Display Audio era covers radios using multiple serial prefixes depending on the trim level:
U####L####— base CD radio serial (10 characters, two halves).HBM####— Display Audio 5"/7" and navigation units.913A####— some Alpine OEM units.
Part numbers printed nearby 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 2014–2021 Odyssey:
- Non-touchscreen base radio: Use preset buttons 1–5 to scroll to each digit, then press and 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. Tap each digit and press OK or Enter on screen.
If the touchscreen is unresponsive, attempt the physical preset buttons — certain units support either input method. Make sure the screen is fully booted before attempting entry.
Why Did the Radio Lock and Ask for a Code?
Honda's Display Audio system carries the same anti-theft design as earlier radios: losing battery power activates a code request at next startup. Applies to both the non-touchscreen radio and the Display Audio touchscreen.
- Battery replacement — by far the most frequent cause.
- Battery disconnect during repairs — service that cuts battery power will re-engage the lock.
- Completely dead battery — a drained battery has the same result.
Note: a number of higher-end Display Audio models from this era might not use a traditional code-based lock — if the radio never prompted for a code after losing power, it may use a different anti-theft method tied to the vehicle VIN.
