2018 Fiat 500 Smart Key Replacement - Fast, Affordable & Professional

Your 2018 Fiat 500 uses a Smart Key. Physically, it's a folding plastic housing with 4 buttons on the face, a CR2032 battery inside powering the remote, and a high-security SIP22 blade that folds into the body. There's also a transponder chip inside the housing that communicates with the car's body control module every time you start the engine.

A flight attendant at her townhouse row parking near Ocean View Hills had a 500 with a cracked flip key. The pivot pin was loose and the blade wouldn't lock into position anymore. She went to the dealer and they told her the only fix was a brand new key, cut and programmed, for $450. What they didn't mention is that the chip and circuit board inside were working fine. She just needed a new shell and blade.

I went to her townhouse that evening with replacement shells and my VVDI Key Tool. Her key's FCC ID was M3N-40821302. I swapped the electronics from her cracked shell into a new housing, verified every button, and cut a fresh SIP22 blade from a lock decode. The aftermarket shells I carry have the same pivot mechanism and button feel as factory.

She paid about $265 for the full job. Her cracked key was her only one, so having it rebuilt plus a spare made means she's covered going forward.
