Why Is the Radio Asking for a Code?
Double-DIN Honda radios carry the same anti-theft design as earlier models: any interruption in battery power activates the code prompt on the next startup. Common causes include:
- Battery replacement or disconnect — by far the most common cause.
- Battery drain — a completely discharged battery has the same effect.
- Fuse replacement — replacing the radio fuse block can briefly interrupt power and activate the lock.
- Workshop electrical work — repairs that involves disconnecting the battery will cause this.
Using the correct code removes the lock and normal function is restored immediately. The lock only comes back if power is cut once more.
How Serial Numbers Work and Where to Find Them on 2014 Honda Fit Radios
The first step is finding the radio serial number.
Most drivers assume the code depends on the Honda model or year, but actually, the unlock process depends on the unique radio unit's serial number.
Each radio has its own serial tied to the security system.
This is even better, because if you have bought a used radio, the VIN or other Honda-specific data wouldn't help.
Depending on the radio version used, you may be able to see the serial directly from the screen or by checking the label on the radio chassis.
Factory Radios on the 2014 Honda Fit
The 2014 model year is the final year of the 2nd-generation GE Fit in North America before the 3rd-generation GK launched for 2015. The factory audio family is unchanged from the rest of the GE generation, so identifying your head unit is still a matter of trim badge and a quick look at the centre stack.
The base Fit carries a 4-speaker AM/FM/CD receiver with an aux input jack and a USB input in the upper part of the glove box - basic monochrome display, no factory Bluetooth. The Fit Sport uses the same single-disc CD receiver but adds two dash tweeters (6 speakers total) and AM/FM/CD/MP3/WMA decoding, with aux and glove-box USB carrying over. The Fit Sport with Navigation replaces the standard CD head unit with the Alpine-supplied AVN-DVD touchscreen navigation receiver (Honda part number 39540-TK6-.), available only on the Sport trim.
To identify yours quickly, look at the centre stack: a single-DIN CD slot with a small monochrome display is the base or Sport non-nav unit, while a wider colour touchscreen with an integrated DVD-based map disc is the Sport with Navigation unit. Glove-box USB jack and front aux are present on all 2014 Fit factory radios from new. All three units use the standard Honda anti-theft system and will display CODE (or Err after a wrong attempt) once they have lost 12V power; the navigation unit additionally has a separate NAV CODE tied to the same chassis serial.
Accessing the Serial Number Through the Radio Menu
The method for 2014 Honda Fit is this:
The 2014 Honda Fit is equipped with a double-DIN head unit featuring a dot-matrix screen. The serial number can be displayed using the preset button method:
- Turn ignition to ON or ACC. The radio shows "CODE" or "ENTER CODE".
- Press and hold buttons 1 and 6 simultaneously for 3-5 seconds.
- The screen reveals the serial number in two segments: first half (e.g.,
U3210) then second half (e.g.,L0482).
Tip: On some 2014 Fit radios with navigation, the serial may also appear in the Settings → System Information menu. Try this first if your model has a touchscreen unit.
Reading the Serial on the 2014 Fit Without Removing the Radio
The 2nd-gen GE Fit head units fitted to the 2014 Fit support Honda's dealer-mode preset shortcut, so in most cases you can read the radio's 8-character serial number directly from the dash without pulling the unit.
Sit in the driver's seat with the doors closed and turn the ignition to the ON/II position (engine does not need to be running). Make sure the radio is off. Press and hold preset buttons 1 and 6 at the same time, then - while still holding them - press the power/volume knob to switch the radio on. The display alternates between a U screen showing the first 4 characters of the serial (for example U2200) and an L screen showing the last 4 (for example L0055). Ignore the U and L letters; the actual serial is the 8 characters that follow them combined (for example 22000055).
If the shortcut does not work, confirm you held 1+6 before pressing power, not after. If the unit is already in lockout (Err on screen), the dealer-mode display can be unavailable until the lockout clears. On the Sport with Navigation unit, the same 1+6 trick still applies to the head unit's audio side - the chassis serial it returns is what Honda's portal expects. If the 1+6 method does not give a clean serial, the next step is the physical removal procedure to read the serial from the chassis label.
Taking Out the Radio to View the S/N on the Tag
If the serial does not appear on display, the next step is checking the radio itself.
Many Honda radios require physical access to the serial sticker attached to the unit.
Typical approach:
- Start by completely shutting off the engine - pull the key out.
- Then remove the dashboard bezel.
- Next, loosen the mounting points and move the radio forward.
- Look for a barcode label showing the serial number.
If the button method is unavailable on your 2014 Honda Fit:
- Switch off the vehicle.
- Pry off the radio bezel with a trim removal tool. The 2014 Fit's double-DIN radio sits within a bezel secured with snap clips.
- Unscrew the 4 Phillips screws securing the radio in the bracket.
- Ease the unit forward to view the serial label on the metal casing.
Tip: The 2014 Fit's double-DIN radio weighs more than single-DIN units. Support it firmly when sliding it out.
Removing the Factory Radio on the 2014 Fit
If the dealer-mode 1+6 shortcut does not give a clean serial and the wallet card and glove box sticker are missing, the most reliable way to read the serial on a 2014 Fit is to pull the head unit out and copy the chassis label directly. The 2nd-gen GE centre stack is held by retaining clips with a small number of screws, so the work is straightforward but should be done with care because of the SRS airbag wiring near the dash.
Safety first
Turn the ignition fully off and remove the key from the cylinder. Disconnect the negative terminal of the 12V battery and wait at least three minutes before working near the dash so the SRS capacitor can fully discharge. Avoid touching or pulling on any yellow airbag connectors while the trim is loose.
Tools you will need
A Phillips screwdriver for the radio retaining screws, a plastic trim/panel pry tool to release the dash bezel clips without scratching the surface, an 8mm socket or short driver for any nutted fasteners hidden behind the cup-holder panel, and a phone or camera for a clear photo of the chassis label.
Removal overview
Pop out the small panel above the cup-holders in the centre console - it is clipped, not screwed, and the access hole on the far right reveals a hidden Phillips screw. Gently pry off the centre dash bezel that surrounds the radio and HVAC controls, walking the pry tool around each clip until the bezel comes free, and disconnect any wiring (hazard switch, etc.) from the back of the bezel before setting it aside. Remove the visible Phillips screws securing the radio to the dash frame, slide the head unit forward, and unplug the wiring harness and antenna lead from the rear of the unit.
Where the serial is printed
Look on the top, side or rear face of the metal chassis for a white or silver thermal-printed label. The label carries a Honda part number (for example 39100-TK6-A01 on non-nav units, 39540-TK6-.. on the Alpine navigation unit) and a separate serial line. Copy the longest alphanumeric string next to the barcode; that is the serial, not the part number.
Tips
Photograph the label rather than copying by hand, so characters such as O vs 0 and I vs 1 can be re-checked later. Reassembly is the reverse of removal: connectors back on, screws home, bezel pressed in until each clip seats, then reconnect the battery and enter the radio code to bring the unit back online.

Typical Serial Number Examples for 2014 Fit
The 2014 Honda Fit radio serial number uses the standard Honda OEM format:
U1234L5678– Primary Honda factory format – two halves displayed separately (U####thenL####), combined into a 10-character serial
Radio manufacturers for the 2014 Fit: Alpine (most common) or Panasonic. Nav models may have a separate module but typically use the same U/L two-part serial format.
Reminder Record the complete serial exactly – a single wrong digit will generate an incorrect code.
Common Serial Number Formats on 2014 Fit Radios
Factory Honda head units in the 2014 Fit carry a printed serial number on the chassis label and also expose it via the 1+6 dealer-mode shortcut. Both methods give the same 8-character alphanumeric string, which is what Honda's online code portal and any third-party Honda code service expect.
The serial is an alphanumeric string of 8 characters printed next to the barcode on the chassis label. On the dash, the dealer-mode display splits the same 8 characters into two screens: U + first 4 (for example U2200) and L + last 4 (for example L0055). The label also lists a Honda part number - 39100-TK6-A01 on the non-nav single-CD head unit, or 39540-TK6-.. on the Alpine touchscreen navigation unit. These are part numbers, not serials, and should not be entered into a code lookup tool.
To use the serial, combine the U and L digits with no leading letter and no separator - for example, U2200 + L0055 becomes 22000055. Double-check ambiguous characters such as O vs 0 and I vs 1 by comparing the dash readout with the printed label, especially if the OLED segments are dim. If your string does not look like an 8-character alphanumeric serial, confirm that you copied the serial line and not the Honda part number, which sits separately on the same label.
Unlocking the Radio After Code Generation
Once you receive the correct unlock code based on the serial number, you can restore default functionality by entering it into the unit.
The code entry process depends on the control layout, but most 2014 Fit 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 SAFE displayed on screen.
The Correct Way to Enter It
To input the code on the 2014 Honda Fit's radio:
- Ignition ON. Radio shows "CODE".
- Press preset buttons 1-5 to enter each digit of the 5-digit unlock code. Each button rotates through digits 0-9.
- Hold button 6 for 2 seconds to accept.
Lockout: 3 failed attempts = 60-minute lockout. Keep ignition ON for the full hour. Turning off the ignition restarts the lockout timer.
Entering the 5-Digit Code on the 2014 Fit
Once you have the correct 5-digit anti-theft code for your 2014 Fit radio, the entry process is fast, but you have a strict attempt limit before the radio locks itself out, so verify the code and the serial it came from before you start.
You only get around 10 attempts. After roughly ten consecutive wrong codes, the factory Honda radio enters a lockout state and the display shows Err or E. To clear the lockout, leave the ignition in the ACC/ON position with the radio powered up for one continuous hour, then try the correct code again. Cycling the key off does not always shortcut the timer, so do not hammer guesses at the unit.
To enter the code by presets, turn the ignition to ACC or ON so the radio powers up and shows the CODE prompt. Press preset 1 the number of times needed for the first digit of the 5-digit code (press once for 1, twice for 2, etc.). Press preset 2 for the second digit, 3 for the third, 4 for the fourth, and 5 for the fifth - the radio normally accepts the code automatically and resumes audio. The 2014 Fit non-nav head unit also accepts the code via the tuning knob - rotate to set each digit, then press SCAN, TUNE or the power button to confirm. On the Sport with Navigation, the on-screen keypad is the primary method - tap each digit on the touchscreen, then confirm.
If it does not unlock, stop after the second wrong attempt and re-verify the 8-character serial number you used to obtain the code, making sure no leading letter or trailing digit was dropped. If Err appears, leave the ignition in ACC/ON for the full one-hour cooldown before retrying.
How Serial-Based Honda Fit Radio Unlock Works
- Skip long troubleshooting discussions or service visits - you can generate the code online with the radio serial number.
- Identify your radio's serial. You will always find it on the unit itself, and sometimes you can see it on the Fit's display.
- Enter it into the field above, and our software will calculate the correct 2014 Fit unlock code.
- When you receive the code, input it using Fit's radio controls to unlock the system successfully.
- The entire process takes only a few minutes and requires zero paperwork and no dealer visit.
Understanding Unlock Issues with Your Fit
The serial number format for the double-DIN Honda radio follows one of:
U####L####— the standard two-part Honda serial (first half starts with U, second with L).HBM####— found on navigation and some premium configurations.913A####— used by Alpine-manufactured units.
Honda part numbers on the same label begin with 39100 or 39101 — do not use those. If uncertain, use the 1+6 button method to retrieve the serial on the screen itself.
When the head unit turns on without showing the "CODE" screen, consider these possibilities:
- It could still be unlocked — attempt normal operation to confirm.
- Certain 2014 Fit radios display "ENTER CODE" rather than just "CODE" — both message means the same thing.
- With navigation models: the navigation display may come up first the code screen. Wait a few seconds for the audio system to boot separately.
Should no code screen ever show, verify the radio has power — a failed radio fuse will stop the unit from powering on.
After three wrong codes, the mid-era Honda radio enters lockout mode and shows an error or goes silent. To recover it:
- Leave the ignition in the ON position — don't switch it off.
- Allow the full 60 minutes to elapse. Turning the key to OFF at any point restarts the waiting period.
- After the hour, the radio should show "CODE" again.
Navigation-equipped 2014 Fit units follow the same 60-minute lockout process. Should it remains locked after waiting, the unit may need a dealer diagnostic.
The mid-generation Honda radio uses an identical button layout as the older single-DIN platform:
- Preset buttons 1–5 — each press scrolls through digits 0–9 to set that digit of the code.
- Button 6 — press and hold for several seconds to confirm the full code.
For certain 2014 Fit navigation-equipped radios, the preset buttons may be arranged slightly differently or accompanied by soft keys. In those cases, the confirmation button is typically the rightmost preset or a dedicated ENTER key.
An incorrect code result on the double-DIN Honda is very often traced back to a misread serial. The serial label on the back of the radio contains both the serial and the part number — confirm you copied the serial (U####L####) and not the part number.
If the code was rejected after one attempt, avoid entering more guesses — you only have three tries before a 60-minute lockout. Reach out to us with the serial for a no-charge reverification before retrying.
