Renault Kadjar Radio Code — Unlock It Online

Q: How to Enter the Code

The entry method varies by infotainment generation: Touchscreen units (R-Link 2, Media Nav Evolution): A numeric keypad appears automatically on screen when the unit requires the code. Tap in your four (or more) digit code and confirm. Button-based units (Update List, Tuner List): Use preset buttons 1–4 to select each digit. Press button 5 or 6 (depending on unit variant) to confirm. On some units the steering wheel volume knob or mute button completes the entry.

Q: Where is the serial number on my Kadjar R-Link unit?

On the R-Link 2 touchscreen system, go to Settings → About to find the serial or unit identifier. On non-touchscreen Renault radios in the Kadjar, you will need to access the sticker on the head unit body, which usually requires partially removing the unit from the dashboard.

Has your Renault Kadjar stereo stopped working after a battery replacement, a flat battery, or electrical work? The radio has locked itself as an anti-theft measure, and all you need to restore it is the unit's serial number — typically a PRE-code or a number beginning with a Renault-specific prefix — and the matching unlock code. This guide covers both Kadjar generations (2015–2022).

Why the Kadjar Radio Locks

Renault fits all Kadjar stereos with an anti-theft lock that activates whenever the unit loses power. The system spans every radio from the entry-level Update List unit through to the R-Link 2 and Media Nav Evolution touchscreen systems. The lock is tied to the unit's serial number, so the code is unique to your specific radio. Other Renault models such as the Clio, Mégane, and Captur use the same approach.

Finding the Serial Number on a Renault Kadjar

Renault uses what is commonly called a PRE-code — a serial or reference code printed on the radio itself or retrievable from the unit's settings menu. The method depends on which system is fitted:

Media Nav / R-Link (touchscreen): Go to Settings → System → About or System Information. The serial number or unit code is displayed on screen. Note the full string exactly.
Update List / Tuner List (non-touchscreen): The serial is usually on a sticker on the side or top of the head unit. You may need to partially remove the unit using trim tools to read it.
Carminat Navigation: Access the engineering menu by pressing the ESC button for several seconds, or check the label on the unit itself.

Once you have the serial, look up your Renault Kadjar code online for a fast result.

Troubleshooting Lockouts on the Kadjar

If too many incorrect codes are entered, Renault radios impose a temporary lockout:

Waiting period: Typically 60 minutes with ignition on before another attempt is allowed. The display may show a timer or simply appear frozen.
Multiple lockouts: Repeated wrong codes extend the waiting time. Always source the correct code before attempting entry.
Permanent lock: After an excessive number of wrong attempts, some units require a dealer reset. A Renault dealer can re-programme the unit using the vehicle's VIN and proof of ownership.

Frequently Asked Questions

Where is the serial number on my Kadjar R-Link unit?

On the R-Link 2 touchscreen system, go to Settings → About to find the serial or unit identifier. On non-touchscreen Renault radios in the Kadjar, you will need to access the sticker on the head unit body, which usually requires partially removing the unit from the dashboard.

My Kadjar has Media Nav — is the process the same?

Yes. Media Nav Evolution uses the same PRE-code approach. The serial is accessible via the touchscreen settings menu, and the code is entered via the on-screen numeric keypad that appears automatically.

Does the code work after every battery replacement?

Yes — the code is permanently tied to the head unit's serial number and does not change. Keep it safe so you can re-enter it after future battery work without needing to look it up again.

Can I get the code from a Renault dealer?

Renault dealers can retrieve the code from their database using the VIN and proof of ownership. However, using an online lookup service with your serial number is considerably quicker and available 24/7.
