SUPALAND Nissan/Infiniti 5-Button Smart Proximity Key Fob Replacement — KR5S180144014, Pre-tested with Battery

This SUPALAND five-button replacement key fob is a ready-to-program smart proximity remote compatible with Nissan Altima and Maxima (2016–2018) and Infiniti Q50/Q60 models.

When the original key fob is lost, damaged, or the buttons wear out, a direct-fit OEM-style replacement can restore keyless entry and push-to-start convenience. SUPALAND supplies a pre-tested remote with battery and electronics installed so you receive a functioning unit that still requires professional programming by an auto locksmith or dealer. The remote matches FCC ID KR5S180144014 and aligns with common OEM part numbers, making it easier to source a compatible spare or permanent replacement.
