SUPALAND Replacement Key Fob for Toyota Prius 2004-2009 — 2nd Gen Silver-Logo 3-Button, Preinstalled Electronics

If your Prius keyless remote is lost, damaged, or no longer communicating, this SUPALAND replacement fob matches the factory specifications for the MOZB31EG / P/N:2584A-B31EG (FCC ID: MOZB31EG, also referenced as 89994-47061). The unit ships with the circuit board and batteries already in place and has been bench-tested before sending. It is intended for vehicles that originally used the silver logo-style key; double-check your original key’s markings and appearance before ordering to avoid incompatibility.

How do I confirm this fob fits my Prius?

Verify compatibility by matching the part numbers, FCC ID, and the logo color of your existing key. If any of these differ, the fob may not work for your vehicle.

• Confirm FCC ID: MOZB31EG (printed on original remote).
• Match part numbers: P/N 2584A-B31EG or 89994-47061.
• Ensure your original key displays the silver logo style — other logo colors are not supported.
• If unsure, consult a dealership or a certified locksmith before purchase.

What must I do after receiving the replacement remote?

The fob arrives with electronics and batteries installed but will not operate with your car until the transponder key is cut and the remote is programmed. Programming can be completed by you in some cases or by a professional if no working key exists.

• Have the metal key blank cut to match your vehicle’s ignition key.
• Program the remote to your Prius following the vehicle’s programming steps, if you have at least one working key.
• If you lack a working key, arrange programming and key cloning with a dealership or qualified locksmith.
• Contact SUPALAND support if you need guidance about matching OEM details prior to buying.

What’s included and what should I expect from assembly/testing?

Each package contains one 3-button remote with the internal electronics and batteries pre-installed and tested. The unit does not include a decorative logo on the back and arrives ready for cutting and programming.

• One SUPALAND 3-button key fob housing with electronics installed.
• Batteries fitted and basic bench tested for transmitter function before shipping.
• Blank metal key for cutting to your vehicle’s profile (cutting service not included).
• Note: The remote you receive will not carry the OEM logo on the back.

Can I program this myself or do I need a professional?

Some Prius models allow self-programming when you already have a working key. Without an existing key, programming requires dealership or locksmith tools. Always verify your vehicle’s capabilities before attempting DIY programming.

• Self-programming possible only if at least one original working key is available.
• No working key means professional programming and possible immobilizer enrollment are necessary.
• Errors from purchasing the wrong key cannot be fixed by returns if part mismatch occurs — check OEM details first.

Who is this replacement fob for? This SUPALAND key fob is aimed at owners of Toyota Prius second-generation models (2004–2009) that originally shipped with the silver-logo remote and who need an OEM-style electronic replacement. It’s ideal for DIY mechanics comfortable with key cutting and remote programming when a working key exists, and for locksmiths or dealerships sourcing a tested replacement transmitter for clients. If you cannot confirm your original key’s part numbers or logo color, contact SUPALAND support or a professional for compatibility help before purchasing to avoid an unusable remote.
