Formawerx has designed custom keys for classic Porsches and Land Rovers but now the company is making its way to Japan with its first-ever JDM key. The sculptural design of the Ignition FD pays tribute to the Mazda's famed rotary engines and is CNC machined from 303 stainless steel and finished in silver or PVD black. Built to factory specifications, the keys are compatible with the Mazda RX-7 (FD) series from 1993-2002 and the Mazda Miata (NA) series from 1989-1997.
