Nissan & Infiniti Proximity Keys

Shop Nissan and Infiniti proximity keys for automotive locksmith services, replacement-key jobs, and inventory restocking. Noble Key Supply carries an extensive selection of smart keys for compatible Nissan and Infiniti vehicles, including OEM, aftermarket, and refurbished options.

The collection features numerous button configurations, transponder chips, frequencies, FCC IDs, and manufacturer part numbers. Always compare the replacement key’s specifications with the original key and vehicle before ordering.

Nissan and Infiniti Smart Key Replacement Options

Nissan Intelligent Keys and Infiniti proximity keys provide keyless-entry and push-to-start functionality on compatible vehicles. Some Nissan applications also use proximity fobs designed for twist-ignition systems.

Available configurations may include:

  • Three-, four-, and five-button smart keys
  • Push-to-start and twist-ignition proximity fobs
  • Remote-start, trunk, hatch, and panic functions
  • OEM, aftermarket, and refurbished keys
  • Multiple transponder-chip technologies
  • 315 MHz, 433 MHz, and 434 MHz frequencies
  • Emergency insert-blade compatibility

Because similar-looking smart keys can contain different electronics, appearance alone should not be used to determine compatibility.

Nissan Intelligent Keys

Nissan Intelligent Keys are available for numerous compatible cars, trucks, SUVs, and vans. Depending on the vehicle, the button layout may include lock, unlock, panic, trunk release, rear hatch, or remote start.

Before selecting a replacement, verify the vehicle’s year and model along with the original key’s FCC ID, frequency, chip, buttons, and Nissan part number.

Infiniti Proximity Keys

Infiniti smart keys use many of the same identification methods as Nissan proximity keys, but compatibility can vary by model, year, trim level, and installed system. Some products support specific Nissan and Infiniti applications, while others are intended exclusively for one brand.

Matching the FCC ID and part number is especially important when selecting an Infiniti proximity-key replacement.

Multiple Transponder-Chip Technologies

This collection includes keys using several transponder technologies, such as ID46, 47, and 4A chips. The correct chip must communicate with the vehicle’s immobilizer system for successful programming and vehicle operation.

Two keys with the same shell and buttons may contain different chips. Confirm the chip type shown in the product specifications before purchasing.

315 MHz, 433 MHz, and 434 MHz Smart Keys

Nissan and Infiniti proximity keys are manufactured with different operating frequencies. Common options in this collection include 315 MHz, 433 MHz, and 434 MHz.

Frequency differences are not interchangeable. The replacement key must use the correct frequency for the specific vehicle and market.

Match the FCC ID

The FCC ID is one of the most reliable identifiers when matching a Nissan or Infiniti smart key. FCC IDs found throughout this collection may include:

  • KR55WK48903
  • KR55WK49622
  • CWTWB1U840
  • CWTWBU729
  • CWTWBU735
  • CWTWB1G744
  • KR5S180144014
  • KR5TXN1
  • KR5TXN3
  • KR5TXN4
  • KR5TXPZ1

Compare the complete FCC ID on the original key with the replacement product. Even a small difference can indicate another frequency, circuit board, or vehicle application.

Verify the Manufacturer Part Number

Nissan and Infiniti proximity keys may also be identified through their manufacturer part numbers. Examples represented in the collection include:

  • 285E3-JA05A
  • 285E3-6CA6A
  • 285E3-3SG0D
  • 285E3-4RA0B
  • 285E3-3TP0A
  • 285E3-9HS4A
  • 285E3-9HP5B
  • 285E3-6CA1A
  • 285E3-1LB5A
  • 285E3-5RA6A
  • 285E3-9PA5A
  • 285E3-6RA5A

Use the part number together with the FCC ID, frequency, chip type, and button layout for a more accurate match.

Push-to-Start and Twist-Ignition Fobs

Not every Nissan proximity key is designed for a push-button ignition. Certain Nissan vehicles use an Intelligent Key with a dashboard-mounted twist ignition. These fobs may look similar to push-to-start keys but operate with a different vehicle system.

Confirm whether the vehicle uses push-button start or a twist ignition before selecting a replacement.

OEM, Refurbished, and Aftermarket Proximity Keys

Noble Key Supply offers several options for professional replacement-key services.

OEM Nissan and Infiniti Keys

OEM proximity keys use original-equipment components and are intended for their listed applications. They are a suitable option when an original Nissan or Infiniti product is preferred.

Refurbished OEM Keys

Refurbished keys reuse genuine OEM electronics and provide another option for compatible vehicles. Depending on the application, a refurbished key may require unlocking, resetting, or preparation before it can be programmed to another vehicle.

Aftermarket Smart Keys

Aftermarket proximity keys provide a cost-effective replacement for supported Nissan and Infiniti applications. Carefully review the specifications of each product to confirm compatibility and programming requirements.

Button Layouts and Remote Functions

The correct replacement should have the same number of buttons and functions as the original key. Available layouts may support:

  • Lock and unlock
  • Panic alarm
  • Trunk release
  • Rear-hatch release
  • Remote start

Do not assume that an additional or missing button will work after programming. Match the layout and icons to the vehicle’s original equipment.

Professional Programming Is Required

Nissan and Infiniti proximity keys generally require professional programming before they can operate the vehicle. Programming procedures vary based on the model, year, key system, chip, and condition of the replacement key.

A qualified automotive locksmith or key technician can confirm programming-tool coverage, prepare the key when necessary, cut the compatible emergency blade, and complete the programming procedure.

How to Choose the Correct Nissan or Infiniti Proximity Key

Confirm the following information before ordering:

  1. Vehicle year, make, model, and trim
  2. Push-to-start or twist-ignition system
  3. FCC ID
  4. Manufacturer part number
  5. Transponder-chip type
  6. Operating frequency
  7. Number of buttons
  8. Remote functions and button icons
  9. Emergency insert-blade style
  10. OEM, aftermarket, or refurbished condition
  11. Programming-tool compatibility

Checking every available identifier helps prevent incorrect orders, failed programming attempts, and service delays.

Shop Nissan and Infiniti proximity keys for automotive locksmith services, replacement-key jobs, and inventory restocking. Noble Key Supply carries an extensive selection of smart keys for compatible Nissan and Infiniti vehicles, including OEM, aftermarket, and refurbished options.

The collection features numerous button configurations, transponder chips, frequencies, FCC IDs, and manufacturer part numbers. Always compare the replacement key’s specifications with the original key and vehicle before ordering.

Nissan and Infiniti Smart Key Replacement Options

Nissan Intelligent Keys and Infiniti proximity keys provide keyless-entry and push-to-start functionality on compatible vehicles. Some Nissan applications also use proximity fobs designed for twist-ignition systems.

Available configurations may include:

  • Three-, four-, and five-button smart keys
  • Push-to-start and twist-ignition proximity fobs
  • Remote-start, trunk, hatch, and panic functions
  • OEM, aftermarket, and refurbished keys
  • Multiple transponder-chip technologies
  • 315 MHz, 433 MHz, and 434 MHz frequencies
  • Emergency insert-blade compatibility

Because similar-looking smart keys can contain different electronics, appearance alone should not be used to determine compatibility.

Nissan Intelligent Keys

Nissan Intelligent Keys are available for numerous compatible cars, trucks, SUVs, and vans. Depending on the vehicle, the button layout may include lock, unlock, panic, trunk release, rear hatch, or remote start.

Before selecting a replacement, verify the vehicle’s year and model along with the original key’s FCC ID, frequency, chip, buttons, and Nissan part number.

Infiniti Proximity Keys

Infiniti smart keys use many of the same identification methods as Nissan proximity keys, but compatibility can vary by model, year, trim level, and installed system. Some products support specific Nissan and Infiniti applications, while others are intended exclusively for one brand.

Matching the FCC ID and part number is especially important when selecting an Infiniti proximity-key replacement.

Multiple Transponder-Chip Technologies

This collection includes keys using several transponder technologies, such as ID46, 47, and 4A chips. The correct chip must communicate with the vehicle’s immobilizer system for successful programming and vehicle operation.

Two keys with the same shell and buttons may contain different chips. Confirm the chip type shown in the product specifications before purchasing.

315 MHz, 433 MHz, and 434 MHz Smart Keys

Nissan and Infiniti proximity keys are manufactured with different operating frequencies. Common options in this collection include 315 MHz, 433 MHz, and 434 MHz.

Frequency differences are not interchangeable. The replacement key must use the correct frequency for the specific vehicle and market.

Match the FCC ID

The FCC ID is one of the most reliable identifiers when matching a Nissan or Infiniti smart key. FCC IDs found throughout this collection may include:

  • KR55WK48903
  • KR55WK49622
  • CWTWB1U840
  • CWTWBU729
  • CWTWBU735
  • CWTWB1G744
  • KR5S180144014
  • KR5TXN1
  • KR5TXN3
  • KR5TXN4
  • KR5TXPZ1

Compare the complete FCC ID on the original key with the replacement product. Even a small difference can indicate another frequency, circuit board, or vehicle application.

Verify the Manufacturer Part Number

Nissan and Infiniti proximity keys may also be identified through their manufacturer part numbers. Examples represented in the collection include:

  • 285E3-JA05A
  • 285E3-6CA6A
  • 285E3-3SG0D
  • 285E3-4RA0B
  • 285E3-3TP0A
  • 285E3-9HS4A
  • 285E3-9HP5B
  • 285E3-6CA1A
  • 285E3-1LB5A
  • 285E3-5RA6A
  • 285E3-9PA5A
  • 285E3-6RA5A

Use the part number together with the FCC ID, frequency, chip type, and button layout for a more accurate match.

Push-to-Start and Twist-Ignition Fobs

Not every Nissan proximity key is designed for a push-button ignition. Certain Nissan vehicles use an Intelligent Key with a dashboard-mounted twist ignition. These fobs may look similar to push-to-start keys but operate with a different vehicle system.

Confirm whether the vehicle uses push-button start or a twist ignition before selecting a replacement.

OEM, Refurbished, and Aftermarket Proximity Keys

Noble Key Supply offers several options for professional replacement-key services.

OEM Nissan and Infiniti Keys

OEM proximity keys use original-equipment components and are intended for their listed applications. They are a suitable option when an original Nissan or Infiniti product is preferred.

Refurbished OEM Keys

Refurbished keys reuse genuine OEM electronics and provide another option for compatible vehicles. Depending on the application, a refurbished key may require unlocking, resetting, or preparation before it can be programmed to another vehicle.

Aftermarket Smart Keys

Aftermarket proximity keys provide a cost-effective replacement for supported Nissan and Infiniti applications. Carefully review the specifications of each product to confirm compatibility and programming requirements.

Button Layouts and Remote Functions

The correct replacement should have the same number of buttons and functions as the original key. Available layouts may support:

  • Lock and unlock
  • Panic alarm
  • Trunk release
  • Rear-hatch release
  • Remote start

Do not assume that an additional or missing button will work after programming. Match the layout and icons to the vehicle’s original equipment.

Professional Programming Is Required

Nissan and Infiniti proximity keys generally require professional programming before they can operate the vehicle. Programming procedures vary based on the model, year, key system, chip, and condition of the replacement key.

A qualified automotive locksmith or key technician can confirm programming-tool coverage, prepare the key when necessary, cut the compatible emergency blade, and complete the programming procedure.

How to Choose the Correct Nissan or Infiniti Proximity Key

Confirm the following information before ordering:

  1. Vehicle year, make, model, and trim
  2. Push-to-start or twist-ignition system
  3. FCC ID
  4. Manufacturer part number
  5. Transponder-chip type
  6. Operating frequency
  7. Number of buttons
  8. Remote functions and button icons
  9. Emergency insert-blade style
  10. OEM, aftermarket, or refurbished condition
  11. Programming-tool compatibility

Checking every available identifier helps prevent incorrect orders, failed programming attempts, and service delays.
