If your original Mini Cooper smart key is lost, damaged, or failing to communicate, this Aichiyu replacement remote provides a complete hardware swap: battery, transponder chip, circuit board and an uncut metal key blade. It’s built to match the CAS system configuration used in Mini Coopers from 2006 through 2013 and transmits on the 315MHz frequency—confirming the FCC ID printed on your original remote is essential before ordering.

How do I verify this remote matches my original key?

Match the FCC ID and button layout on your current remote to ensure compatibility. The product is specifically designed for remotes labeled IYZKEYR5602 or KR55WK49333 and fitted with three buttons: lock, unlock, and power door release.

• Check the FCC ID stamped on the front of your original remote.
• Confirm your vehicle year is between 2006 and 2013.
• Ensure your original remote has the same three-button arrangement.

What programming or cutting steps are required after purchase?

This remote is sold blank and requires a qualified locksmith or dealership to cut the emergency key and program the transponder to your car’s CAS system. Self-programming is not possible—the car’s diagnostic interface must be used to register the new key.

• Professional diagnostic programming is needed; locksmiths are typically faster and less costly than dealers.
• Bring your vehicle and proof of ownership to the programmer.
• The remote arrives complete with battery and internal chip ready for programming.

• Transponder chip preinstalled for dealer/locksmith programming.

Will this remote work with my car’s frequency and CAS system?

Yes—this fob communicates on 315MHz and is built to the CAS system parameters used in the specified Mini Cooper model years. Confirming the FCC ID on your old remote eliminates mismatch risks.

• 315MHz frequency to match original Mini Cooper configurations.
• Designed for CAS-equipped models 2006–2013.
• Not compatible if your original FCC ID differs from the listed IDs.
