2012 Infiniti M56 Smart Key Replacement - Fast, Affordable & Professional
The OEM versus aftermarket question on 2012 Infiniti M56 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 Del Mar asked me directly whether the key would be "as good as dealer." He had a 2012 Infiniti M56 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 CWTWB1U787, 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 $289. Dealer charges $539 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.

“The dealership quoted me $600 for a new Honda key. EZ Car Keyz did it for $225, same day, cut and programmed at my house. Works perfectly. Everyone should know this is an option.”
“A+ service at an even better price. Tim was a lifesaver. I lost my original and only key for my Audi and he was willing to come to my location at 8pm the same day. He worked fast, communicated clearly, and made sure everything worked before leaving.”
“I called over 40 locksmiths trying to get a key made for my Audi A6 and nobody could do it. Tim made it easy, fast, and affordable. He showed up with a smile and got the job done without any stress. Absolute wizard with keys.”
