My 2011 Honda key was starting to crack and fall apart, so I bought a new case online with hopes to move everything over but it came with a new key blade. Newer cars have the "laser cut" keys that the hardware store typically cannot cut. I called and he came the next day after work to cut the key and reassemble the housing. About 100 bucks but I've seen the machine to cut laser keys cost 1000's. Worth 100 bucks and he came to me.
