My key is worn out and i need a new one . How much does it cost.
Well, since your location is unknown or if you plan to use a dealer or a lock smith all I can say is call around for estimates. If you are in the US many hardware store like ACE will make keys with chips.
I had to do one for a '16 Civic. I don’t remember the exact cost but it was $100 - $130 from my locksmith. Call a Honda dealer, a locksmith, and I had Batteries Plus do one for my Toyota.
