MechanMagic Key Fob Remote Replacement Fits for Nissan Sentra 2013-2019/Rogue 2008-2015/Versa 2007-2015
Quick take
This MechanMagic key fob remote replacement is designed for specific Nissan and Infiniti vehicles and comes as a 2-pack with electronics and batteries pre-installed. It can be a budget-friendly way to replace a remote, but it is not a plug-and-play DIY job, the key and remote portion must be cut and programmed by a qualified locksmith or dealership. It also won’t work on push-button ignition or smart-key style systems.
Pros and cons
Pros
- Includes electronics and batteries pre-installed in the key fobs (so you are not sourcing separate parts).
- Compatible with listed part numbers and FCC IDs, and sold as a 2-pack.
- Built for regular-key vehicles only, with an ID 46 chip configuration.
- Professional locksmith tools are used to pre-test the remotes before shipping.
Cons
- Programming is required, cutting the key and matching the transmitter must be done with specialized equipment.
- Not compatible with push-start, smart/proximity, or other PEPS style systems.
- Buyer compatibility hinges on matching the correct FCC ID (some model years have multiple possibilities).
- Some programming attempts may need follow-up, because remotes can start the car while button functions still require proper learning.
What buyers think
Buyer-review evidence is limited but directionally consistent on a few decision points. Reviews commonly emphasize that the product is usable value when you plan for professional programming, and that it is not intended for DIY setup. Some buyers report mixed programming outcomes (for example, the vehicle starts but lock/unlock button behavior needs additional learning), which suggests that matching and programming steps matter. A small number of reviews also point out incompatibility when the vehicle year or key system type does not align (for example, the wrong vehicle generation or a system that is not supported).
How this key fob replacement is meant to work
This is a replacement remote key fob that targets select Nissan and Infiniti models. The set is designed for regular key vehicles and includes the electronics and battery inside the fob body. It is intended to be cut and programmed by a qualified locksmith or dealership so the transmitter and ignition chip sync correctly with your vehicle.
Compatibility checklist before you buy
Remote key fob replacements live or die by compatibility. Before purchasing, confirm your vehicle supports the right key type and that the transmitter identifiers line up.
- Key system type: This transmitter supports regular key vehicles. It is not supported for push-start or smart/proximity (PEPS) style systems.
- FCC ID matching: Compatibility depends on matching the correct FCC ID. Some model years can have more than one FCC option, so verify yours.
- Part number and chip: The fob is associated with specific part numbers and an ID 46 chip configuration.
- Vehicle model and year: It is listed for multiple Nissan and Infiniti lines across a range of years. Use the fitment list and, when applicable, ensure the FCC ID matches your specific remote.
Programming and locksmith expectations
Plan for professional programming. You will typically need key cutting and transmitter/ignition matching, especially because this product is described as not supporting onboard programming and as requiring specialized equipment. This is also why the listing is framed for vehicles that use conventional key systems rather than push-to-start.
If you only replace the remote housing without matching the key chip and transmitter correctly, you can end up with partial functionality (for instance, starting works but lock/unlock buttons do not until the remote learning is properly completed).
Pros and cons in real-world buyer terms
Good fit if you need a replacement remote and you already have a plan for programming
If you are comfortable paying a locksmith or dealership to cut and program the key, this kind of replacement can be a straightforward way to restore remote access for supported Nissan and Infiniti vehicles.
Not a good fit if your vehicle uses push-start or smart key
If your car uses push-button ignition or proximity smart-key systems, this transmitter format is not intended for that setup. In that case, you will likely need a different replacement type that explicitly supports your key system.
Compatibility mistakes can lead to partial or no function
Because FCC ID and chip configuration matter, double-check identifiers before you order. The product can also be sensitive to correct programming steps, so allow time for the locksmith to fully configure all remote buttons.
Price and availability
The product is positioned as an entry-priced key fob replacement (and it is sold as a 2-pack). Availability is indicated as in stock.
Verdict
The MechanMagic key fob remote replacement can be a solid value for drivers with compatible Nissan or Infiniti vehicles that use regular keys, especially when you are ready to bring the key and remote to a qualified locksmith for cutting and programming. It is not a DIY-friendly option, and it is not meant for push-start or smart-key systems, so confirming your FCC ID and key system type is the smartest first step.

The Samfolk Faraday Box with Faraday Bags is a compact, wood-and-PU-leather styled signal-blocking case for keyless car fobs and other small valuables.
