Step-by-Step Honda Fit 2010 Radio Code Retrieval Guide
Getting your radio code takes only 4 easy steps.
- Locate your radio's serial number - this is the only info required by our side.
The difference with the dealership lookup is that no VIN is needed. - Enter the serial number into our generator above.
Our system checks it against a database of supported factory radios and automatically finds the matching anti-theft code. - In most cases, the code appears 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. - Once you get it, simply enter it into the radio to restore the functionality.
Final Step - Enter the Radio Code
Once you receive the correct unlock code based on the S/N, you can restore normal functionality by entering it into the unit.
The code entry process depends on the control layout, but most 2010 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 CODE displayed on screen.
Detailed Entering Instructions for Fit 2010
To input the code on the 2010 Honda Fit's radio:
- Ignition ON. Radio displays "CODE".
- Use preset buttons 1-5 to enter each digit of the 5-digit unlock code. Each button cycles through digits 0-9.
- Press and hold button 6 for a few seconds to accept.
Lockout: 3 wrong attempts = 60-minute lockout. Keep ignition ON the entire time. Turning off the ignition restarts the lockout timer.
Entering the 5-Digit Code on the 2010 Fit
Once you have the correct 5-digit anti-theft code for your 2010 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.
Limited attempt warning
- You only get around 10 attempts. After roughly ten consecutive wrong codes, the factory Honda radio enters a lockout state and the display shows
ErrorE. - 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.
Entering 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 for2, etc.). - Press preset 2 for the second digit.
- Press preset 3 for the third digit.
- Press preset 4 for the fourth digit.
- Press preset 5 for the fifth digit - the radio normally accepts the code automatically.
Entering the code with the tuning knob
- The 2010 Fit 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 used to obtain the code.
- Make sure no leading letter or trailing digit was dropped from the serial.
- If
Errappears, leave the ignition in ACC/ON for the full one-hour cooldown before trying again.
Finding the Radio S/N for Honda
The initial step is to find and write down the radio's serial num.
Based on the head unit type used in your 2010 Fit, the S/N can usually be accessed either through the screen menu or by checking the label on the radio itself.
Follow the steps below to identify your S/N the right way.
Factory Radios on the 2010 Honda Fit
The 2010 model year is the second year of the 2nd-generation GE Fit, with the same factory audio family as the 2009 launch year. Honda kept the lineup simple: two single-DIN CD-based receivers across the line, with one optional touchscreen navigation unit at the top of the range. The trim badge and a quick look at the centre stack are enough to tell the three apart.
- Fit (base) - 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 Bluetooth from the factory.
- Fit Sport - the same single-disc CD receiver but with two additional dash tweeters (6 speakers total) and AM/FM/CD/MP3/WMA decoding; aux + glove-box USB carry over.
- Fit Sport with Navigation - the optional Alpine-supplied AVN-DVD touchscreen navigation receiver (Honda part number
39540-TK6-.) replacing the standard CD head unit on the Sport trim only.
Quick visual ID
- Single-DIN CD slot with a small monochrome display - that is the base or Sport non-nav radio.
- Wider colour screen with a touchscreen and an integrated DVD-based map disc - that is the Sport with Navigation unit.
- Glove-box USB jack and front aux jack - present on all 2010 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.
Using Hidden Radio Menus to Find the Serial
The method for 2010 Honda Fit is this:
The 2010 Honda Fit uses a double-DIN radio featuring a dot-matrix screen. The serial number can be retrieved 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 at the same time for about 5 seconds.
- The screen shows the serial number in two segments: first half (e.g.,
U3210) then second half (e.g.,L0482).
Tip: On certain 2010 Fit radios with navigation, the serial may also appear in the Settings → System Information menu. Check this first if your vehicle has a touchscreen unit.
Reading the Serial on the 2010 Fit Without Removing the Radio
The 2nd-gen GE Fit head units 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. This is the same procedure documented by Honda dealer service departments for 2007-2020 Honda vehicles and it is widely confirmed for the 2010 Fit on owner forums.
Step-by-step
- 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.
- While still holding 1 and 6, press the power/volume knob to switch the radio on.
- The display alternates between a
Uscreen showing the first 4 characters of the serial (for exampleU2200) and anLscreen showing the last 4 (for exampleL0055). - 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 (
Erron 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.
Fit's Hardware Label Method
If the serial number cannot be accessed on-screen, use the hardware method.
Most Honda Fit factory radios include a tag with the serial number printed on the casing.
Step-by-Step:
- Turn off the vehicle.
- Lift the bezel surrounding the radio.
- Release the fasteners.
- Slide the unit forward to access the label.
The serial number is usually located near the manufacturer sticker.
If the 1+6 method is unavailable on your 2010 Honda Fit:
- Turn off the vehicle.
- Remove the radio bezel with a plastic pry tool. The 2010 Fit's larger radio sits within a trim panel secured with clip fasteners.
- Remove the four Phillips screws fastening the radio in the bracket.
- Slide the unit out to access the serial label on the metal casing.
Tip: The 2010 Fit's double-DIN radio weighs more than older units. Hold it with both hands when extracting it.
Removing the Factory Radio on the 2010 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 2010 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 and 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.
- Wait at least three minutes before working near the dash so the SRS capacitor can fully discharge.
- Stay clear of any yellow airbag connectors while the trim is loose.
Tools you will need
- Phillips screwdriver for the radio retaining screws.
- 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.
- 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. There are three different access holes; the one on the far right reveals a hidden Phillips screw.
- Gently pry off the centre dash bezel that surrounds the radio and HVAC controls. Walk the plastic pry tool around each clip until the bezel comes free.
- 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.
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-A01on 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.

Common S/N Formats Used on 2010 Fit Units
The 2010 Honda Fit radio serial number follows the standard Honda OEM format:
U1234L5678– Standard Honda factory format – two halves displayed separately (U####thenL####), combined into a 10-character serial
Radio manufacturers for the 2010 Fit: Alpine (most common) or Panasonic. Navigation models may have a separate module but typically use the same U/L two-part serial format.
Reminder Write down the full serial exactly – a single wrong character will produce an incorrect code.
Common Serial Number Formats on 2010 Fit Radios
Factory Honda head units in the 2010 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.
What the serial typically looks like
- 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 exampleU2200) andL+ last 4 (for exampleL0055). - The label also lists a Honda part number -
39100-TK6-A01on the non-nav single-CD head unit, or39540-TK6-..on the Alpine touchscreen navigation unit. These are part numbers, not serials.
What to copy
- Combine the U and L digits with no leading letter and no separator - for example,
U2200+L0055becomes22000055. - Double-check ambiguous characters such as O vs 0 and I vs 1 by comparing the dash readout with the printed label.
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.
Why Is the Radio Asking for a Code?
Double-DIN Honda radios have the same anti-theft system as earlier models: any break in battery power causes the code prompt on the next startup. Common causes include:
- Battery replacement or disconnect — the most frequent cause.
- Battery drain — a completely discharged battery has the same effect.
- Fuse replacement — swapping the radio fuse can momentarily cut power and trigger the lock.
- Workshop electrical work — repairs that involves disconnecting power will produce this.
Supplying the correct code removes the lock and the radio resumes normal operation immediately. The lock only comes back if power is disconnected again.
Fixing Common Code Entry Problems for 2010 Fit
After 3 wrong attempts, the double-DIN Honda radio goes into lockout mode and shows an error or refuses input. To reset it:
- Keep the ignition in the ON position — don't switch it off.
- Wait the full 60 minutes to elapse. Turning the key to OFF at any point resets the waiting period.
- Once 60 minutes have passed, the radio will display "CODE" again.
Nav 2010 Fit units use the same 60-minute lockout process. Should it remains locked after waiting, the unit may need a dealer diagnostic.
When the head unit comes on without displaying the "CODE" screen, consider these scenarios:
- It could still be unlocked — test normal operation first.
- Some 2010 Fit radios show "ENTER CODE" rather than just "CODE" — both prompt means the same thing.
- On nav-equipped units: the nav screen may come up first the code screen. Wait a few seconds for the audio system to initialize separately.
If no prompt ever show, verify the radio has power — a blown radio fuse will prevent the unit from powering on.
An incorrect code result on the double-DIN Honda is almost always traced back to the wrong serial number being submitted. The serial label on the back of the radio contains both the serial and the part number — verify you copied the serial (U####L####) and not the part number.
After a rejected attempt, do not entering more guesses — there are only three tries before a 60-minute lockout. Contact support with the serial for a no-charge reverification before retrying.
The serial number pattern for the mid-generation Honda radio is one of:
U####L####— the standard two-part Honda serial (first half starts with U, second with L).HBM####— found on navigation and certain premium units.913A####— used by Alpine-manufactured units.
Honda part numbers on the same label begin with 39100 or 39101 — never submit those. When in doubt, use the 1+6 button method to retrieve the serial on the screen itself.
The mid-generation Honda radio uses the same button layout as the older single-DIN platform:
- Preset buttons 1–5 — each press scrolls through digits 0–9 to enter that digit of the code.
- Button 6 — hold for several seconds to confirm the full code.
On some 2010 Fit nav units, 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.
