Aichiyu Mini Cooper Smart Remote Key Fob Replacement — 3‑Button 2006–2013 CAS 315MHz (Includes Battery & Immobilizer Chip)

Aichiyu’s smart key replacement is a fully assembled, 3‑button Mini Cooper remote (FCC IYZKEYR5602 / KR55WK49333) built to work with CAS systems on 2006–2013 models at 315MHz.

This is a complete aftermarket remote key fob designed to replace lost or damaged Mini Cooper smart keys that use the FCC IDs IYZKEYR5602 or KR55WK49333. The fob ships ready with battery, immobilizer chip, remote circuit board, and an uncut emergency key blade — but it requires professional cutting and diagnostic programming to pair with your vehicle. Read the compatibility notes and programming requirements below so you know what to expect before purchasing.

How do I confirm this remote matches my original key?

Check the face of your existing remote for the FCC ID and part number before buying. The Aichiyu replacement only fits models that exactly match FCC IYZKEYR5602 or KR55WK49333 and use the CAS immobilizer setup.

• Locate FCC ID on the front of your original remote.
• Confirm your Mini Cooper year is between 2006 and 2013.
• Verify the vehicle uses a CAS system and 315MHz frequency.

What comes inside the package and what is pre-installed?

The remote arrives complete—battery included—so you receive the full electronics and immobilizer chip already fitted. The emergency key blade is uncut so a locksmith or dealer can cut it to your vehicle’s locks.

• Preinstalled battery and remote circuit board for immediate power.
• Immobilizer transponder chip integrated on the board.
• Uncut mechanical emergency key for local cutting to match your locks.

Do I need a locksmith or dealer to make the key work?

Yes. This remote needs diagnostic programming and key cutting from a qualified automotive locksmith or dealership; self‑programming is not available. Many independent locksmiths offer faster and less expensive service than dealers.

• Diagnostic programming required to register the remote to your car’s CAS system.
• Local locksmiths can cut the emergency key and program immobilizer functions.
• Bring proof of ownership and original VIN information when requesting service.

Which vehicle functions does the replacement remote control?

The Aichiyu fob replicates the primary remote functions found on compatible Mini Cooper smart keys. Confirm your original key’s button layout before ordering to ensure feature parity.

• Lock and unlock the doors with dedicated buttons.
• Power door release/back gate button for hatch operation.
• Works as a full remote once programmed and keyed by a professional.

Who is this for? The Aichiyu replacement remote is intended for Mini Cooper owners (2006–2013) who need a complete, ready‑assembled smart key fob to replace a lost or damaged unit that shows FCC IYZKEYR5602 or KR55WK49333. Choose this product if you want a full electronics package—including battery and immobilizer chip—knowing that a professional locksmith or dealer will perform the final cutting and diagnostic programming to make the key function with your vehicle.
