MechanMagic Nissan/Infiniti 3-Button Key Fob Remote CWTWB1U751 2007-2015 — ID46 315MHz, Pre-tested with Battery

MechanMagic CWTWB1U751 key fob replacement is a brand-new, pre-tested 3-button remote compatible with many Nissan and Infiniti models that requires cutting and professional programming before use.

If your original remote is lost, damaged, or the buttons no longer respond, this direct-fit replacement offers the same FCC ID and part-number family for a wide range of Nissan and Infiniti vehicles from 2007–2015. The unit ships with battery and electronics installed and is tested in-house; however, it does not come pre-cut or dealer-programmed. You’ll need a locksmith or dealership with the appropriate transponder tools to cut the key blade and program the transponder chip and remote functions.

How do I install and program this key fob?

The physical installation is straightforward if you already have the key blade cut and the vehicle accepts aftermarket remotes. Programming the transponder and remote functions requires specialized equipment; most buyers choose a locksmith for speed and compatibility because some dealers decline to program aftermarket remotes.

• Step 1: Have the key blade cut to match your lock by a locksmith or hardware service
• Step 2: Bring the remote and vehicle to a locksmith or dealer for transponder and remote programming
• Step 3: Verify all buttons (lock/unlock/panic) and remote start functions, if applicable
• Tip: Provide the part number or FCC ID to the programmer to speed service

What comes in the box and what should I expect from quality?

Each MechanMagic replacement arrives fully assembled with battery and internal electronics installed and professionally tested before shipment. It’s sold as a brand-new aftermarket fob—ready to be cut and programmed—and includes the standard 3-button face layout common to the supported models.

• Included: 1 x MechanMagic keyless remote with battery and electronics
• Condition: 100% new, pre-tested with professional diagnostic tools
• Appearance: 3-button shell; matches pictured layout—verify your vehicle’s remote matches
• Note: This transmitter works on regular keyed vehicles only (not smart/keyless push-start variants)

Are there any fitment or compatibility precautions?

Yes—because multiple OEM part numbers and remote variants exist across years and trim levels, confirm your vehicle’s remote FCC ID, chip type, and physical button placement before ordering. If the vehicle’s original remote or part number differs, this product may not program correctly.

• Check current remote’s FCC ID: CWTWB1U751 or matching part numbers
• Check transponder chip: ID46 required for programming
• Verify vehicle frequency: 315 MHz compatible
• If unsure, use the vehicle fitment tool or consult a locksmith/dealer

Who is this for? MechanMagic’s CWTWB1U751 replacement is aimed at owners of compatible Nissan and Infiniti models who need a cost-effective aftermarket remote and are prepared to have the key blade cut and the transponder programmed by a professional. It’s ideal for drivers replacing a lost or damaged fob who want a new, pre-tested remote that mirrors OEM button layout and frequency—but remember that professional key cutting and programming are required for final operation.
