I have a 2007 and a 2008 Fit. Does anyone know if I cloned sections of one ECU to another if the same key could be used for both cars? Of course a locksmith would change the tumbler setup in one of the cars as well. The VIN section is the main section being cloned. I'm not sure if immobilizer problems would occur. Thanks!

Never mind I just need to put both chips in the same key or put a chip under the dash like for remote start setups.
