What Caused the Radio to Lock?
The single most common cause behind a locked radio on Renault vehicles, but there are a few others worth knowing:
- Battery swap or disconnect: The most frequent cause by far on Renaults. Renault radios lock every time the battery is disconnected or replaced. This is extremely common, even when the battery is only disconnected briefly.
- Buying a used Renault: The original code is rarely passed on when a car changes hands. Private sellers and dealers frequently cannot provide it.
- Flat battery from sitting: A battery drained from sitting unused triggers the code request when power is restored.
- Workshop or service work: Any work involving the battery — including an MOT, tyre change, or oil change — can trigger the lock.
Can't Locate Your Unit's S/N? Follow The Steps Below for Renault Clio 2017
The first part is to locate the radio's serial num.
Depending on the radio unit installed in your 2017 Clio, the serial can be found either through the display menu or by checking the label on the radio itself.
Below are the most common methods to identify your serial the right way.
Factory Radios on the 2017 Renault Clio
The 2017 Clio runs the post-facelift (Phase 2) head-unit lineup with three main variants.
Base trims continue with the Renault-Bosch Tuner List, a single-DIN unit with a monochrome display and six fascia preset keys. Mid trims commonly run MediaNav Evolution, a 7-inch landscape touchscreen with a single-processor architecture and integrated mapping on the Evolution variant. Higher trims and option packs upgrade to R-Link Evolution, a 7-inch portrait touchscreen tablet with TomTom navigation, steering-wheel and satellite-remote controls. Quick field test: a fascia full of numeric presets is Tuner List, a landscape 7-inch screen with a basic UI is MediaNav Evolution, and a portrait 7-inch tablet branded R-Link is R-Link Evolution.
Check the Display First - Serial Retrieval Without Tools
The method for 2017 Renault Clio is this:
The 2017 Renault Clio features a Renault OEM radio or MediaNav system. Many Renault radios do not support an on-screen serial number retrieval method.
The serial number is located on a sticker on the radio unit. The radio must be partially removed to read it. Some newer Clio with MediaNav may show the serial in Settings → System.
Fast Serial Lookup Using Radio Controls
Display-based pre-code retrieval on the 2017 Clio is documented only for the Tuner List unit.
Renault Tuner List
Set the ignition to ACC so the radio powers up without starting the engine. Press and hold preset 1 together with preset 6 for approximately five seconds. The display switches to a four-character pre-code formatted as one letter followed by three digits, for example V123. Record the pre-code carefully and check for 0 vs O and 1 vs I.
MediaNav Evolution and R-Link Evolution do not surface a user-readable pre-code on screen and are usually retrieved by VIN or by reading the chassis label.
Releasing the Unit to Access the S/N on the Tag
If the serial number cannot be accessed through menu, use the removal method.
Most Renault Clio factory radios include a label with the serial number printed on the casing.
Step-by-Step:
- Switch off the vehicle.
- Remove the dashboard frame surrounding the radio.
- Release the clips.
- Move the unit slightly out to access the label.
The serial number is usually located near the barcode.
To find the serial on the 2017 Renault Clio:
- Power down the vehicle.
- Locate the release slots on each side of the radio. Renault radios typically use DIN-style removal holes.
- Insert extraction tools and pull the radio forward.
- Find the serial on the barcode label on the chassis. It starts with BP.
Tip: Renault radio release keys are the same DIN-style tools used for Fiat vehicles.
Find the Serial by Pulling Out the Radio Unit
When the on-screen method is unavailable, the manufacturer label on the chassis provides the pre-code.
Safety: turn the ignition off, remove the key, disconnect the negative battery terminal, and wait several minutes before touching the dash. Stay clear of yellow SRS airbag connectors throughout the procedure. Use plastic trim tools where any prying is required.
Tools commonly needed: Renault DIN release keys (Tuner List uses two release slots per side at roughly 38 mm centre spacing), plastic trim removal tools, a small Phillips or Torx driver, flashlight, and a phone to photograph the label.
For the Tuner List, insert all four keys fully into the side slots until they click; the locking tabs release and the radio slides out by the keys. For MediaNav Evolution or R-Link Evolution, ease the bezel surround with plastic tools, remove the visible mounting screws, and carefully slide the screen module forward. These touchscreen modules are more integrated and have more connectors than a DIN radio - if resistance is high or the wiring is unclear, consult a professional rather than force the assembly.
The barcode sticker is typically on the top, side, or rear of the chassis. The pre-code is the four-character group printed near a Security or SECU marker, or the last four characters of the longer Renault part number. Photograph the label and re-check ambiguous characters before submission. The unlock code itself is not printed on the unit; only the serial is.

These are the Common Serial Formats
The 2017 Renault Clio radio serial formats:
BP####– Blaupunkt radio serial (standard)CC####– Continental radio serialPH####– Philips radio serialPR####– Other Renault OEM format
The serial is printed on the radio casing. Don't confuse it with the Renault part number.
Typical Serial Number Examples for 2017 Clio
The serial format is determined by the radio manufacturer rather than the Clio nameplate. Three formats apply across the 2017 model year.
Renault-Bosch Tuner List: the pre-code typically consists of one letter followed by three digits, for example A123 or S432. On the chassis label, the longer Renault part number commonly begins with 2811; the trailing four characters are usually the pre-code. The label often marks this block as Security, SECU, or PRE-CODE.
MediaNav Evolution and R-Link Evolution: these touchscreen head units use internal Renault identifiers and do not consistently expose a clean four-character user-readable pre-code. Unlock is most commonly retrieved by VIN.
Validation tips: do not submit the long part number, EAN barcode, or option code as the serial. Re-check 0 vs O, 1 vs I, and 8 vs B before submission.
How Code Entry Works on Your Renault Radio
Now that you've generated 2017 Renault Clio anti-theft code from the S/N, you're ready to reactivate the radio.
Many drivers get stuck at this stage because input process can look different across radio versions, but it's usually quick.
When the radio shows dashed lines, it means the unit is waiting for the correct numbers.
Step-by-Step - Correct Entering Process
To enter the code on the 2017 Renault Clio:
- Ignition ON. Radio displays "CODE" or four dashes (----).
- Press preset buttons 1-4 to enter each digit of the 4-digit code. Each press cycles the digit (0-9).
- Hold button 5 or button 6 to confirm.
Lockout: Multiple incorrect entries will trigger a lockout. Leave the radio for about 30 minutes, then retry.
Detailed Input Instructions for Clio 2017
Once the unlock PIN is issued for the 2017 Clio, enter it carefully. The procedure depends on the factory radio fitted.
Limited Attempt Warning: Renault head units allow only a small number of incorrect attempts before entering a wait state, and reported delays roughly double with each mistake (commonly 1, 2, 4, 8, 16, 32 minutes). Be confident in the code before pressing confirm.
Renault Tuner List: Switch the ignition to ACC and power the radio on. The display shows CODE followed by 0000. Press preset 1 repeatedly until the first digit appears, then preset 2 for the second, preset 3 for the third, and preset 4 for the fourth. Press and hold preset 6 for about five seconds until a beep confirms acceptance. If a region prompt appears (OTHERS, AMERICA, JAPAN, ASIA, ARABIA), scroll with the seek arrows and long-press preset 5 to confirm.
MediaNav Evolution and R-Link Evolution: on power up the screen presents an on-screen numeric keypad. Tap the four PIN digits and confirm with OK or the tick icon. If WAIT or ERROR is displayed, leave the ignition on and the unit powered until the timer expires before retrying.
Fast Renault Clio Radio Unlock Process Explained
Getting your radio code takes only a few simple steps.
- Find your radio's serial number - this is the only information required to generate the correct unlock code.
The difference with the dealership lookup is that 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 , just in case.
If manual verification is required (rare situations), you'll be informed before checkout. - When you receive it, just enter it into your radio to restore the functionality.
Understanding Unlock Issues with Your Clio
Should the radio refuse your code, check these points before entering it again.
- Verify the serial prefix: Renault radios take serials starting with BP, CC, PH, or PR. Confirm you submitted the correct serial from the radio label — not any other sticker inside the car.
- Look for digit confusion: On worn or faded labels, characters are easily confused. Take a clear photo and examine it carefully.
- Entry method: Each press of a preset button advances the digit by one. Pressing too quickly can skip over the correct digit. Press deliberately and count. Hold button 5 or 6 to confirm only after all four digits are set.
If it keeps failing? Send us your serial and order number and we'll check and reissue if needed.
The screen reads "WAIT" or "SAFE" after 3 wrong code attempts, blocking further input until the timer resets.
To clear the lockout: Turn the ignition to ON and leave it there for a full 60 minutes. Turning the ignition off starts the wait again from the beginning. The timer resets every time power is cut.
With Renault vehicles, voltage can drop if the ignition is on for an extended period without the engine running. Run the engine or use a battery maintainer where practical to keep voltage stable.
Code entry on Renault Clio radios relies on the preset station buttons to build the code digit by digit.
- Button 1 controls the first digit — pressing it cycles from 0 to 9.
- Button 2 controls digit 2, button 3 digit 3, button 4 digit 4.
- Once all four digits are correct, press and hold button 5, button 6, or the Enter / AM-FM button to submit the entry.
Note: Some later Renault models use an on-screen keypad instead of preset buttons. If a number pad appears on screen, tap it directly. No hold-to-confirm is needed.
Should "CODE" or the four dashes not appear, work through these steps:
- Trigger the code request: Pull the radio fuse briefly, refit, and turn the ignition on. The radio should then request the code.
- Check if already unlocked: When all functions work normally without restriction, it is not locked. No code entry is needed.
- MediaNav units: Renault MediaNav does not show a code prompt the same way. Check Settings → System for unlock or serial options.
- Some units need ACC or ON: Some Blaupunkt/Philips units may only show the code prompt when the ignition is in ACC or ON. Try both.
Finding the serial on Renault radios is on a label on the rear or side of the radio unit, only accessible after removing the unit.
- What to look for: Look for a string beginning with BP, CC, PH, or PR then numbers and letters.
- Label condition: Labels on higher-mileage vehicles are sometimes worn. Photograph under good light and zoom in — detail is easier to read in a zoomed image.
- Removal tools: Pin-release extraction tools fit all Renault radios. Insert into the release slots on each side and pull forward.
Do not use the vehicle VIN or dashboard label number — they are not the radio serial and will generate the wrong result.
