There are two ways to program a key on Nissan Micra K12 depending on the diagnostic tool used.

Method 1 – Glove Box Code (Budget method)
Requires reading the code from the glove box and entering it into the scanner.

Method 2 – Direct Programming (Advanced method)
No glove box code required. The scanner handles security access automatically.

When buying a replacement key for Nissan Micra K12, make sure it has:

• 433 MHz frequency
• PCF7946A chip
• Hitag 2 / ID46 immobilizer
• compatible PCB marked 5WK4 876 or 5WK4 818
• key blade that can be cut to match the original key

Notes about programming

This type of key uses a combined remote + transponder chip (PCF7946A).

That means:

• remote locking is programmed automatically
• immobilizer chip is programmed during the same key learning procedure

No separate remote pairing is required.

1. Insert the original key into the ignition and switch ignition ON.

2. Open the diagnostic scanner and navigate to:

   Special Functions → IMMO → Nissan → Free PIN Code

   This function allows programming keys without manually calculating the immobilizer PIN.

3. The scanner will ask for the Glove Box Code.

   Locate the 12-digit code on the sticker inside the glove box.

   Use the middle number from the sticker.

   Enter the code into the scanner.

4. Follow the instructions on the scanner screen.

   Insert the key and switch ignition ON, then press OK.

5. The scanner will ask:

   “Is the immobilizer indicator off?”

   If the immobilizer light is no longer flashing, select YES.

6. Switch ignition OFF when requested and press OK.

7. The scanner will ask if you want to program another key.

   Insert the new key, switch ignition ON, and confirm.

   Repeat the process for each key.

8. After the last key is programmed, the scanner will display:

   Programming complete

   Turn ignition off and test all keys.

This method uses an advanced key programming tool (Autel IM608) which can perform key learning without requiring the glove box code.

The tool automatically handles immobilizer security access, making the process faster and easier.
