MechanMagic Remote Key Fob Replacement for Nissan Altima & Maxima 2016-2018 — 5-Button, Ready-to-Program

If your original remote is lost, damaged, or starting to fail, this MechanMagic unit gives you a direct-fit replacement that mirrors factory button layout and functions. It arrives fully assembled—battery and internal electronics already in place—so a professional locksmith or dealership can complete final programming and sync it to your vehicle.

Will this remote work with my Nissan or Infiniti?

The remote is manufactured to be compatible with FCC ID KR5S180144014 and matches OEM part numbers commonly used on late-model Nissan/Infiniti push-start vehicles. Confirming fit with your VIN or the vehicle-fit list is recommended before purchasing.

• Compatible models include Nissan Altima and Maxima (2016–2018).
• Also fits Infiniti Q50 (2016–2019) and Q60 (2017–2018).
• Cross-references OEM numbers 285E3-4RA0B, 285E34RA0B, and S180144310.
• Check your vehicle’s FCC ID or consult a locksmith/dealer for final verification.

How is this remote prepared out of the box?

MechanMagic ships this key fob fully assembled so you won’t need to handle tiny parts or install the battery. Each unit is professionally tested before shipping to ensure the electronics are functional and ready for programming.

• Battery and internal electronics pre-installed and tested.
• Comes as a complete keyless entry remote—no disassembly required.
• Packed individually to protect electronics during transit.
• Ready for dealer or locksmith programming on arrival.

What steps are required to get the key fob working in my car?

Final activation requires specialized programming tools; the remote cannot be self-programmed at home. A certified locksmith or the dealership will use diagnostic equipment to pair the fob with your vehicle’s immobilizer and push-start system.

• Bring the new remote and your vehicle to a locksmith or dealer.
• They will use OEM-level programming tools to sync the fob to your car.
• Expect programming times to vary by shop—call ahead for estimates.
• Keep your vehicle title/ID handy if the dealer requires proof of ownership.

What should I expect in terms of durability and everyday use?

The housing and buttons are designed to replicate OEM feel and serve as a reliable daily remote. While built to high standards, treating it like any key fob—avoiding drops and prolonged exposure to moisture—will extend lifespan.

• Durable button layout matches original factory design.
• Electronics pre-tested to reduce out-of-the-box failures.
• Standard button functions: lock, unlock, trunk, panic, and remote start (if equipped).
• Keep away from extreme heat, cold, and heavy impacts for best longevity.

Who this is for: This MechanMagic replacement is aimed at drivers of compatible Nissan and Infiniti models who need a cost-effective, OEM-style remote quickly—whether replacing a broken fob, keeping a spare, or restoring full keyless entry after loss. It’s ideal for owners who want a professionally pre-tested unit but plan to use a locksmith or dealer for secure programming and activation.
