2009 Infiniti Ex35 Smart Key Replacement - Fast, Affordable & Professional
The OEM versus aftermarket question on 2009 Infiniti Ex35 keys deserves a direct answer. OEM Infiniti keys come from the factory supplier with the Infiniti logo on the housing, the factory shell, and a luxury price tag. Aftermarket keys use the same blade profile, same chip family, same button layout, and same board design. The functional difference in daily use is zero if the aftermarket fob is good quality.
A product manager at the tech campus in Escondido asked me directly whether the key would be "as good as dealer." He had a 2009 Infiniti Ex35 and wanted a spare he could trust as his everyday fob, not a backup in a drawer. Fair question.
I carry aftermarket blanks tested across hundreds of Nissan and Infiniti jobs. The blade is the same NSN11 profile cut to spec. The chip is the same family the IMMO module expects. His fob, FCC ID KR55WK48903, was a 4-button smart key, and the aftermarket housing has the same feel, weight, and snap-fit as factory. The difference is no Infiniti logo and about $150 less. I decoded his lock with my NSN11 Lishi and verified every cut before handing it over.
His total was $334. Dealer charges $607 for OEM. Where aftermarket goes wrong is cheap blanks with thin shells and inconsistent chips. I test every batch and return anything that doesn't meet my standards.
