MechanMagic Remote Control Key Fob Replacement for 2007-2012 Nissan Altima/ 09-14 Maxima Murano Infiniti FX35/ 08-13 G37 FX50 Q60 QX70 11-12 G25/ 07-08 G35 KR55WK48903 KR55WK49622 (4 Buttons)
Quick take
This MechanMagic 4-button remote key fob replacement is built for specific Nissan and Infiniti vehicles when the FCC ID and part numbers match. It is typically bought as an affordable spare, with multiple buyers reporting smooth button functionality after programming. The main catch is that you cannot self-program at home without the right tools, so plan on a locksmith, dealer, or compatible programming setup.
Pros and cons
Pros
- Vehicle-specific compatibility tied to FCC ID KR55WK48903 or KR55WK49622 and listed part numbers
- Includes two ready-to-program fobs, with the battery and electronics installed
- Programming is achievable through locksmith/dealer or the right diagnostic tool, and users report core button functions working after setup
- Four buttons for common lock, unlock, and trunk release use cases on supported models
Cons
- Programming is not “self-programming” and may require a locksmith, dealer, or compatible programming hardware
- Plastic feel may differ from OEM (a potential concern if you care a lot about tactile match)
- Non-OEM, aftermarket fob (no logo or badge), so appearance may not be identical to original keys
What buyers think
Buyer-review evidence is limited, but the available feedback is consistent on a few decision factors. Several buyers purchased the fobs as spares to avoid dealer replacement pricing and reported that the remotes worked properly once programmed. Users also describe the build as solid and the button functions, such as lock and unlock (and trunk release on compatible vehicles), working as expected after setup. Overall, the main theme is value for supported Nissan and Infiniti models, with programming being the practical hurdle.
Who this key fob replacement is for
- You have a supported Nissan or Infiniti and can confirm the FCC ID and part number match the KR55WK48903 or KR55WK49622 listings (and the compatible part numbers listed).
- You want a spare or you are replacing a lost remote and would rather not pay dealership pricing.
- You can handle programming via a locksmith, dealer, or compatible diagnostic/programming tool. The fobs are designed to be ready to program once you take care of setup.
- You prefer a two-pack so you are not forced to buy again later if you want a second remote.
Who should avoid it
- You cannot verify FCC ID and part numbers. This is a compatibility-sensitive replacement, and mismatched remotes will be unusable.
- You expect full self-programming at home. Self-programming is not supported, so you should budget time and effort for a locksmith/dealer visit or compatible programming hardware.
- You need an OEM-appearance badge/logo. This is an aftermarket replacement, so branding may not match your original key.
Key features and specs that matter
- Compatibility: Supports select Nissan and Infiniti models when the FCC ID is KR55WK48903 or KR55WK49622 (the listing also calls out specific model year ranges and one FCC ID limitation for some vehicles).
- Part-number matching: Compatible with listed part numbers including 285E3-JA05A, 285E3-JA02A, 285E3-JA000, and 285E3-JK62A.
- Frequency: 315 MHz.
- Button layout: Four-button remote.
- Power: Uses a lithium coin or button cell battery (3V), and batteries/electronics are installed on arrival.
- In the box: Two key fobs described as ready to program, plus battery and circuit board components.
Programming: what to expect before you buy
These remotes are intended for replacement use, but programming is not described as self-service. In practice, buyers typically plan for either a locksmith/dealer programming appointment or using a compatible diagnostic/programming tool. If you already have a tool that can handle key fob programming for your vehicle, setup may be straightforward. If not, confirm that your local locksmith or key shop is willing to program aftermarket fobs before you purchase.
Pros and cons in real buying terms
Potential wins
- Lower-cost replacement path: The two-pack format can reduce the chance of being stuck with only one working remote.
- Ready-to-program hardware: The fobs arrive with battery and electronics installed, so you can focus on programming rather than disassembly.
- Verified function after programming: Reviews mention reliable button behavior once programmed on compatible vehicles.
Tradeoffs to consider
- Programming effort is required: If you cannot use a locksmith or compatible tool, this product will not solve the key problem by itself.
- Feel and appearance may not match OEM: Some buyers note differences in plastic feel, and it is an aftermarket key without a logo badge.
Price and availability
The product is listed as available, and pricing can change. If you are comparing options, focus on the total cost (key fob plus expected programming) rather than the fob price alone.
Verdict
The MechanMagic remote key fob replacement is a solid choice if you have the right Nissan or Infiniti fitment match and you are prepared for programming through a locksmith/dealer or compatible tool. It is especially appealing as a spare because you get two ready-to-program fobs, and the available review feedback suggests the remotes function correctly once properly set up. If you need a perfect OEM tactile match or want to avoid programming entirely, you may want to consider different approaches before buying.
FAQ
How do I confirm this key fob replacement will work with my car?
Check your vehicle’s remote’s FCC ID and compare it to KR55WK48903 or KR55WK49622 (and verify the part numbers listed). Compatibility is tied to those identifiers and specific model year ranges.
Does this key fob support self-programming at home?
No. Programming is expected to be handled by a locksmith/dealership or with the right diagnostic/programming hardware. The fobs are described as ready to program, but setup still requires programming.
What’s included in the package?
The pack includes two key fobs described as ready to program, with the battery and electronics installed (plus a battery/circuit board component set).
Is this compatible with nissan versa, altima, and 370Z?
Compatibility is model- and year-specific, and the listing highlights FCC ID constraints for certain vehicles (for example, Versa sedan and 370Z with a specific FCC ID). Confirm your FCC ID and part number match before ordering.
Will it look exactly like the OEM key fob?
It is an aftermarket replacement, so it may not include an OEM logo or badge, and some buyers note differences in the plastic feel compared with original fobs.
What battery does it use?
It uses a 3V lithium coin or button cell battery type.
Should I buy this if I only need one key?
This set provides two fobs, which can be helpful if you want a spare or a backup. If you only need a single remote, you may want to compare with other options that offer single-fob replacement, since this one is packaged as a two-count.
