How is the remote prepared and what arrives in the box?

Each SUPALAND key fob is fully assembled with its battery and internal electronics already installed and checked before shipping. You receive one remote that’s been pre-tested with professional locksmith equipment to ensure the board and transmitter function correctly, minimizing installation surprises.

What do I need to program this fob and can I program it myself?

This SUPALAND unit requires programming by an authorized locksmith or dealership because it does not support vehicle self-programming. A professional will pair the remote to your vehicle's immobilizer and keyless entry system using diagnostic tools.

• Programming: Dealer or qualified automotive locksmith required.
• Not supported: No DIY self-programming—vehicle security protocols need specialized tools.
• Timing: Programming typically takes a short appointment but varies by shop.

What should I check before ordering to ensure a correct fit?

Confirm the FCC ID printed on your original remote or consult your vehicle documentation to match it to KR55WK48903 or KR55WK49622. Also compare OEM part numbers and model years to the compatibility list to avoid purchasing a non-matching fob.

• Verify FCC ID on your existing remote or owner manual.
• Match OEM part numbers and the vehicle model year against the fitment list.
• If unsure, provide your VIN to a locksmith or dealer for confirmation before purchase.

Who is this for: SUPALAND's pre-tested key fob is intended for owners of supported Nissan and Infiniti models who need a reliable replacement remote and plan to have programming performed by a dealership or certified locksmith. It suits DIY-minded buyers who want a ready-to-program unit without having to source batteries or electronics, and fleet managers who prefer pre-tested spares to minimize downtime. Avoid this product if you have a remote with a different FCC ID or expect to self-program at home.
