Why Did the Radio Lock and Ask for a Code?
Honda's Display Audio system uses the same anti-theft architecture 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 — any work that interrupts battery power will re-engage the lock.
- Completely dead battery — a fully discharged battery has the same result.
Worth knowing: a number of higher-end Display Audio models from the 2014–2021 period do not use a traditional code-based lock — if the radio never showed "CODE" after losing power, it may use a different anti-theft method linked to the vehicle VIN.
How Our Radio Code Generator Works for 2017 Honda HR-V
To get the code, you'll take only a few easy steps.
- Locate the radio's serial number - this is the only info required to generate the correct unlock code.
Unlike dealership lookup, 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 factory radios and automatically retrieves the matching security code. - In most cases, the code appears instantly on the screen after payment and is also sent to your email , just in case.
If we need to check it manually, you'll be notified before checkout. - When you receive it, simply enter it into the radio to restore the functionality.
Code Entry Instructions
After locating the S/N and generated the unlock code, the final part is entering it into your radio.
Honda factory radios display a ENTER CODE message when ready for input.
The process is usually quick, but button layouts and confirmation methods may change depending on the radio version installed in your HR-V.
Correct Entering Process
To input the code on the 2017 Honda HR-V:
- Ignition ON. Radio shows "CODE" or "ENTER CODE".
- Non-touchscreen models: Press preset buttons 1-5 to select each digit, then press and hold button 6 to confirm.
- Display Audio touchscreen: An on-screen keypad may appear. Enter each digit and press "Enter" or "OK".
Lockout: 3 wrong attempts activate a 60-minute lockout. Keep ignition ON. Do not cycle the key or the timer starts over.
Entering the unlock code on a 2017 HR-V radio
- Switch the ignition to ON and power the audio unit so the CODE or ENTER CODE prompt is shown on the 5-inch LX screen or the 7-inch Display Audio screen on EX and EX-L Navi.
- On the LX 5-inch unit, use preset buttons 1 through 5 to set each digit of the 5-digit code in order, pressing each preset the number of times required for that digit, then submit by holding preset 6.
- On the 7-inch Display Audio used by EX and EX-L Navi, the 2017 head unit has no physical volume knob and relies on a capacitive surface, so the 5-digit code is tapped on the on-screen number pad and confirmed with the on-screen ENTER soft key once the full code is visible.
- If the unit appears to reactivate itself when the battery is reconnected, that is the documented Honda audio reactivation behavior described in the owner's manual and no separate code entry is required.
- Repeated wrong entries trigger a temporary lockout that requires the ignition to be left in the ON position for about an hour before another attempt can be accepted.
Where to Find the Serial Number on your HR-V
Very useful thing to know is that factory radios use a specific S/N to identify each unit.
Your security system links the code directly to this serial.
Different from car-specific data such as VIN or registration info, it is not determined by the model or production year, so you'll be able to get it even if you have a radio that you installed afterwards.
Depending on the maker and radio installed in your Honda HR-V, the retrieval method varies.
Here are the most reliable ways to find it.
Factory radios fitted to the 2017 Honda HR-V
- 5-inch color audio system on the LX trim, controlled by physical buttons and a volume knob, with AM/FM, Bluetooth HandsFreeLink, a single USB input and a 4-speaker layout.
- 7-inch Display Audio touchscreen on EX and EX-L Navi trims, with capacitive controls and no physical volume knob, two USB ports, HondaLink, swipe and pinch gestures and a 6-speaker layout that adds tweeters to the LX configuration.
- EX-L Navi pairs the 7-inch Display Audio head unit with Honda Satellite-Linked Navigation and voice recognition built into the same touchscreen.
- The 2017 HR-V Display Audio software does not include Apple CarPlay or Android Auto; smartphone integration on the 1st gen HR-V remains via HondaLink at this point in the model run.
Fast Serial Lookup Using Radio Controls
The method for 2017 Honda HR-V is this:
The 2017 Honda HR-V could have Honda's Display Audio touchscreen (5" depending on trim) or a base non-touchscreen radio. Both types support serial number display via the 1+6 button method:
- Turn ignition to ON. Let the radio to power up. The screen shows "CODE" when anti-theft is active.
- Simultaneously press preset buttons 1 and 6 for 3-5 seconds.
- The serial number appears in two halves (e.g.,
U3210+L0482).
Alternative: On 2017 HR-V with the Display Audio touchscreen, look in Settings → System → Device Information – the serial may be shown there without needing the button combination.
Reading the serial on a 2017 HR-V factory radio
- Switch the ignition to ACC or ON but leave the audio unit powered off, so the dash is awake without the radio playing.
- Press and hold preset buttons 1 and 6 together on the audio unit's preset row.
- While still holding 1 and 6, press the radio power button to wake the unit; on the LX 5-inch unit the service screen used to display the serial is widely reported to appear, while on the 1st gen HR-V Display Audio the on-screen path is less consistently documented.
- Where the screen appears, record the four characters shown after the letter U on the first screen, then wait for the display to alternate and record the four characters shown after the letter L on the second screen.
- Concatenate the two halves in order to obtain the 8-character serial; the U and L are screen prefixes that are not entered into Honda's lookup.
- If the on-screen procedure does not produce a serial on the 1st gen HR-V Display Audio, the value can be read from the chassis label exposed during removal, or pulled by a Honda dealer using the HDS scan tool through the diagnostic connector.
Locate Serial on HR-V's Radio Chassis
If the serial number cannot be accessed via display, use the removal method.
Most Honda HR-V original radios include a sticker with the serial number printed on the chassis.
Step-by-Step:
- Switch off the vehicle.
- Lift the trim surrounding the radio.
- Unscrew the clips.
- Pull the unit outward to access the label.
The serial number is usually located near the barcode.
If none of these methods succeed on the 2017 Honda HR-V:
- Turn off the vehicle.
- Remove the dashboard trim. The 2017 HR-V's integrated dashboard uses plastic clips.
- For Display Audio models: Remove the mounting screws (Phillips-head) securing the display module.
- For standard radios: Remove the four screws holding the head unit.
- Pull the unit forward and find the serial on the label on the back or side.
Note: The touchscreen unit is wider and more integrated than the standard radio. Take care when removing it.
Removing the radio on a 2017 HR-V to read the serial label
- Disconnect the negative battery cable first and wait several minutes for the SRS capacitors to discharge before touching the dash.
- Begin at a lower corner of the center bezel that surrounds the audio unit and climate controls and pull rearward with plastic trim tools to release the perimeter clips; the 1st gen HR-V uses clip-retained trim rather than visible screws around the head unit, so work evenly around the panel.
- As the bezel lifts out, disconnect the hazard switch and any accessory harnesses on its rear and set it aside on a soft cloth.
- Remove the screws that secure the audio unit bracket to the dash frame, then slide the audio unit straight out, supporting it from underneath as the last fastener comes free so it does not drop into the dash.
- Disconnect the antenna lead and the multi-pin connectors on the rear and read or photograph the chassis label on the side or top of the unit; the printed 8-character serial should match the value returned by the on-screen procedure where it is available.
- Reverse the steps for reinstallation, making sure each clip seats with a soft click and that no wiring is pinched between trim panels.

What a Valid Serial Number Looks Like
Based on the radio equipped in the 2017 Honda HR-V:
U1234L5678– Standard Honda OEM formatHBM####– Found on Display Audio and navigation units913A####– Certain Alpine-manufactured radios
The 2017 HR-V 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 read the serial number, not the part number (which starts with 39100, 39101, or similar Honda part coding).
What the 2017 HR-V radio serial usually looks like
- The serial used by Honda's lookup is reported to be 8 characters long on the 1st gen HR-V, with most LX and EX/EX-L Navi units returning a numeric value.
- Where the on-screen procedure works, the first half is shown after the letter U on screen one and the second half after the letter L on screen two; the U and L are screen labels and are not entered into Honda's lookup tools.
- A representative format reads U1234 followed by L5678, corresponding to a stored serial of 12345678 for the lookup.
- Some chassis labels include a longer alphanumeric string with a manufacturer prefix on the printed sticker; the 8 characters that match the on-screen U and L pair are the ones used for the lookup.
- If the printed and displayed serials disagree, the on-screen value is generally the one accepted by the official Honda radio code portal, with the chassis label retained as a fallback when the service screen cannot be triggered.
Troubleshooting Common Radio Problems - HR-V 2017
The Display Audio era includes 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 modules.913A####— some Alpine OEM configurations.
Part numbers on the same label start with 39100 or 39101 — these are not serials. If uncertain, use the Settings → Device Information menu or the 1+6 button method to pull the serial directly from the unit.
When the touchscreen powers on but shows the home screen without any "CODE" display, check the following:
- Anti-theft may not have triggered — certain battery changes don't trigger the lock if done quickly enough.
- Certain Display Audio units, the code prompt shows only on the audio portion of the screen, not the navigation display — give it a moment after startup.
- Try the Settings → System → Device Information route; should the serial appear, the unit may still be functional without a code.
Should none of the above match, 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 is typically caused by the serial was incorrectly noted. Both the button method and the settings menu can produce the correct serial — confirm that the serial you submitted was read off the radio unit and not from a sticker elsewhere in the car.
After one failed entry, stop and contact support before trying again — a second wrong attempt gets you one step closer to the 60-minute lockout. A free serial reverification is available on request.
The Display Audio platform enforces the same 3-attempt lockout as earlier Honda radios. To exit lockout:
- Keep the ignition in ON or ACC — do not switch off.
- Allow the full 60-minute period. The touchscreen may go to sleep during this time — this is expected.
- After 60 minutes, the radio re-displays "CODE" and another attempt is possible.
For touchscreen units, the lockout countdown operates even when the screen is off. Just leave the vehicle running or the ignition on ACC for the full hour.
Code entry depends on the exact radio variant in the Display Audio-era HR-V:
- Non-touchscreen base radio: Press preset buttons 1–5 to scroll to each digit, then press and hold button 6 to confirm — identical to older Honda platforms.
- Display Audio 5" or 7" touchscreen: An on-screen numeric keypad appears when the code prompt is active. Tap each digit and press OK or Enter on screen.
Should the touch input not work, attempt the physical preset buttons — some units accept both input method. Make sure the screen is fully booted before starting entry.
