Micra K11 and K12 radios are Clarion units with a BP or PP serial on the casing label, so the unit has to come out to read it. Later K13 and K14 Micras share Renault hardware and use a short pre-code such as K123. Either way the code is £19.99 here, refunded in full if it cannot be supplied.
Radio codes belong to the head unit serial number, not the vehicle registration or VIN.
A flat battery, battery replacement or radio removal is what triggers the code prompt.

Bob's never displays a guessed or generated code — if a working code can't be retrieved you get a full refund.
2002 to present (K12, K13, K14). Clarion, Bosch, Renault-alliance units
How to find the serial number:
Check the handbook wallet — Nissan dealers frequently recorded the code.
Remove the trim surround and unbolt the unit.
Read the label: a long PP/BP serial means Clarion, a PRE-CODE line means Renault-style.
Note the label wording as well as the number so the right method is used.
How to key the code in:
Presets 1 to 4 set each digit.
On rotary units, turn to select and press to advance.
Confirm with ENTER, OK or preset 5 depending on the unit.
Worth knowing:
K12 (2002–2010): Clarion units, serial usually starting PP or BP on the casing label.
K13 (2010–2016): mixed hardware — some units carry a Renault-style PRE-CODE line.
K14 (2017 on): Renault-alliance platform, so the pre-code method usually applies.
The Micra fascia surround unclips by hand; the unit is then held by four screws.
Two completely different Micras
This is the one that trips people up. A K11 or K12 Micra has a Nissan-Clarion head unit with a long BP or PP serial on a label, and the code has to be looked up against that number. A K13 from 2010 or a K14 from 2017 is built on Renault-alliance hardware, and the label says PRE-CODE followed by a letter and three digits — that is the Renault system, and those are answered instantly on this site.
So before anything else, get the unit out far enough to read the label and see which style of number you have. Following the wrong method wastes an afternoon.
Removing a Micra head unit
On the K12 the vent surround around the radio unclips by hand from the top edge; work along it with a nylon tool rather than levering at one point, because the clips are brittle on cars of that age. Four screws then release the cage. On the K11 the whole centre console panel comes forward, and there is a screw hidden behind the ashtray on some trims.
Read the label on the top face of the casing and photograph it. If the label is faded, angle a phone torch across it — thermal print usually still shows as a raised ghost under raking light.
Price, timing and what not to do
£19.99 against the serial or pre-code, with a full refund if no working code comes back. Renault-format pre-codes are answered on the spot; Clarion BP and PP serials are retrieved by hand, normally the same working day.
Do not feed a Micra serial into a free calculator. The Renault-derived pre-codes are algorithmic, but a Clarion BP number is not, and three wrong entries puts the unit into a lockout that has to time out with the ignition left on.
Does my Micra use a Renault pre-code? Later K13 and K14 Micras share Renault-alliance hardware. If the casing label shows a PRE-CODE line rather than a long serial, follow the Renault method.
Do I have to take the radio out? Usually yes on a Micra — the serial is not shown on screen.
Is the code stored in the car? No. It belongs to the head unit, which is why the unit's own label matters.
How do I find the radio code for a Nissan Micra? Remove the head unit and read the label. A K11 or K12 shows a long BP or PP Clarion serial; a K13 or K14 shows a short Renault-style pre-code such as K123. Enter whichever you have on this page.
How much is a Micra radio code? £19.99, refunded in full if no working code can be supplied. Renault-format pre-codes come back instantly.
Can I get the Micra code without taking the radio out? Only if it was recorded on a card in the handbook wallet or in the service book, which Nissan dealers often did when the car was new. Micra units do not display the serial on screen.
