How much would a new key for my mom's 2010 Honda Civic cost?

Hi.

I had my mom's only spare Honda key on my keychain and I lost it. I'm hoping I'll find it, but if I don't, I'll be paying to get another one made. It has the flat edges around it (dunno the technical term), an alarm button, and a standard lock/unlock button. If I were to take it to a Honda dealership, how much would they charge to get a new copy made? I'm assuming around $100 but would like confirmation.How much would a new key for my mom's 2010 Honda Civic cost?I am a locksmith in Surprise Az , I don't have the software to program those keys. Some locksmiths do some don't. I have been told buy my customers in Surprise that when going to dealerships in Phoenix they have paid between $150-$200 . Locksmiths in Phoenix will usually charge a little more , but they come to you.How much would a new key for my mom's 2010 Honda Civic cost?You won't get that key for $100...try double that. A locksmith specializing in automotive will have the ability to make the key.
