  Important Programming Information

  All new key fobs require professional programming and registration to the vehicle’s immobilizer and ECM. Programming must be completed by an authorized Nissan dealer or qualified locksmith using Nissan CONSULT software.

  Before ordering, verify that your vehicle is equipped with factory remote start, as some trims use a different transmitter. Improper selection or incomplete programming can result in limited operation or security lockout.

  Failing to Program or Match the Key Fob Correctly Can Lead To:

  • Key Not Detected Warning: Vehicle may not start or unlock

  • Inoperative Remote Start: Incorrect part or missing programming sequence

  • Security Lockout: Immobilizer system disables ignition recognition

  • Signal Range Loss: Non-programmed or aftermarket keys can underperform

  Related Components to Inspect or Replace

  • Key Fob Battery (CR2032): Replace yearly for strong signal output

  • Spare Fob: Always keep a second OEM fob for backup and convenience

  • Receiver Antenna: Check if range issues persist after programming

  • Start/Stop Button Switch: Ensure proper response after registration
