Nissan Micra Radio Code — Unlock It Online

Your Nissan Micra's radio is locked and displaying a code prompt — or perhaps it has gone completely silent after the battery was changed. This is the factory anti-theft lock engaging, and it affects all three modern Micra generations: the K12 (2002–2010), K13 (2010–2016), and K14 (2016–2022). Getting back to your music requires one thing: the unique unlock code linked to your radio's serial number. This guide shows you how to find it and how to enter it correctly.

Why Your Nissan Micra Radio Is Locked

Nissan equips its factory audio units — primarily manufactured by Clarion and co-developed with Nissan OEM engineering — with a PIN-lock security system. The lock is triggered any time the unit loses its 12-volt supply, which can happen during a battery swap, a prolonged flat battery, or work on the car's electrical system.

Across the Micra range you may encounter several radio types: a basic OEM AM/FM/CD unit on early K12 models, an OEM CD/MP3 unit on the K13, and a NissanConnect or OEM touchscreen system on the K14. All use the same serial-based unlocking principle, though the entry method varies between button-based and touchscreen units.

Finding the Serial Number

Button combination (K12 and K13)

1. Turn the ignition to accessory position (position II) without starting the engine.
2. With the radio in locked state, press and hold preset buttons 1 and 6 simultaneously for two seconds.
3. The serial number should appear briefly on the display. Record it exactly.

Menu method (K14 NissanConnect)

1. Power on the system; if it shows a lock screen, look for a small information icon or tap Settings.
2. Navigate to System Information or About; the unit serial may be listed there.

Physical label method (all generations)

1. Use DIN extraction keys or appropriate pry tools to remove the head unit from the dashboard.
2. Locate the sticker on the top or side of the unit — this carries the full serial number.
3. Note the number, re-seat the unit, then order your code via our Nissan brand page.

Entering the Code

Push-button units (K12 and K13 base models)

1. Ignition on; radio shows CODE or dashes.
2. Use preset buttons 1–4 to cycle each digit to the correct number.
3. Confirm by pressing the OK or seek button. The radio unlocks.

Touchscreen / NissanConnect (K14)

1. The touchscreen displays a keypad or numeric prompt.
2. Tap each digit of your code in sequence.
3. Tap the confirm or enter button. The system should unlock.

Micra Generation Comparison

Generation	Years	Typical Radio	OEM Supplier	Entry Method
Micra III (K12)	2002–2010	OEM CD / AM/FM	Clarion / Bosch	Preset buttons 1–4
Micra IV (K13)	2010–2016	OEM CD / MP3	Clarion / Nissan OEM	Preset buttons or touchscreen
Micra V (K14)	2016–2022	NissanConnect / OEM touchscreen	Clarion / Pioneer	Touchscreen keypad

Troubleshooting

• CODE appears but buttons do not respond — Ensure the ignition is fully on (accessory position at minimum). Some Micra units require the engine to be running for the entry buttons to activate.
• WAIT message — A timed lockout is active. Leave the ignition on (engine off) for 30–60 minutes and the radio will reset to CODE mode.
• LOCKED — You have exceeded the maximum wrong attempts (typically ten). Leave the ignition in accessory position for one hour, then try the correct code.
• Code rejected on K14 — Check that you have the correct serial number. K14 NissanConnect units sometimes display a partial serial on-screen; ensure you have the full string from the physical label.
• Touchscreen blank after code — Soft-reset the unit by holding the power button for 10 seconds; this reboots the display without affecting the code lock state.

Frequently Asked Questions

Can I get my Micra radio code from a Nissan dealer?

Yes, authorised Nissan dealers can retrieve codes using your VIN and the unit's serial, though this typically requires a service booking, proof of ownership, and an administration fee. For older K12 and K13 units, using an online decoding service with the physical serial number is faster and usually less expensive.

How many wrong codes can I enter before the radio locks permanently?

Most Nissan Micra radios allow up to ten incorrect entries before entering a timed lockout period. The lockout is not permanent — leaving the ignition on (engine off) for 30–60 minutes resets the attempt counter. However, do not guess randomly; order the correct code first to avoid reaching the lockout threshold.

My K12 Micra displays nothing when I try the 1+6 button combination — why?

Not all K12 variants support the button-combination serial display. If the combination does not work, you will need to physically remove the head unit and read the serial from the label. The label method works on all Micra generations.

Does the Nissan Micra have a NissanConnect account that I also need to reset?

The NissanConnect infotainment platform on K14 models has a separate online services account, but this is independent of the radio code lock. Unlocking the radio with a PIN does not require any NissanConnect account action.
