MechanMagic Key Fob Remote Replacement Fits for Nissan

MechanMagic's pre-tested replacement key fob is a ready-to-program, battery-installed remote compatible with many Nissan and Infiniti models using the CWTWB1U816/ID46 transponder.

When your original remote is lost, damaged, or worn out, this MechanMagic keyless entry remote gives you a full-function replacement that arrives pre-assembled with electronics and a battery. It matches common part numbers and FCC IDs for a broad set of Nissan and Infiniti vehicles; final activation requires cutting and programming by a locksmith or dealer. The package contains two identical remotes and printed instructions to guide the next steps.

Which vehicles and part numbers does this remote replace?

This MechanMagic remote is built to substitute OEM fobs tied to specific part numbers and FCC IDs, covering many Nissan and Infiniti model years. Always confirm your vehicle’s FCC ID or part number before ordering, because some models (notably certain Rogue years) use two different remotes.

• Compatible FCC IDs: WTWB1U751, CWTWB1U816 and related OEM part numbers H0561-3AA0B, H0561-3AAOB.
• Common fits: Sentra 2013–2019, Rogue 2008–2015*, Versa 2007–2015, Armada, Maxima, Murano, Pathfinder, Quest, Infiniti FX35/FX45, G35, QX56.
• Note: 2014–2015 Rogues may require matching FCC ID to ensure correct version.

How is the remote delivered and what’s pre-installed?

The remotes arrive fully assembled with the internal board and a working battery already installed, so they're ready for a locksmith to program or for a dealer to cut and enroll. Each order includes two identical units for spare or pair replacement needs.

• Two key fobs per package, new and factory-tested.
• Battery and electronics pre-installed to verify functionality out of the box.
• Printed instructions included on the packaging directing you to the online setup guide.

What steps are required to make this remote work with my car?

This remote is a transmitter only and must be cut and programmed by a qualified locksmith or dealership to match your vehicle’s immobilizer and key blade. It does not support push-button start systems and is intended for vehicles that use a regular keyed ignition.

• Have the key blade cut to match your vehicle’s lock by a locksmith or dealer.
• Program the remote’s transponder (ID46) with dealer-level or locksmith tools.
• Follow the printed package directions to access the online instruction resource; no credit card required to view instructions.

What limitations or compatibility considerations should I know?

This replacement remote is compatible with many models but is not universal. Some vehicles and years use alternative FCC IDs or push-start immobilizer systems that this product doesn’t support.

• Does not work with push-button start vehicles—only regular keyed ignitions supported.
• Check vehicle fitment tool and your OEM FCC ID to avoid ordering the wrong remote version.
• Programming and key cutting are not included; professional service is required to activate the remote.

Who is this for: Drivers of compatible Nissan and Infiniti vehicles who need a cost-effective, ready-to-program replacement remote without buying an OEM unit from a dealership. It’s ideal for vehicle owners who can arrange professional key cutting and programming or for locksmiths and repair shops that provide those services.
