How much is a Ford key replacement?

I have a 2005 Ford car and this weeken I locked my keys in my car THREE TIMES! I started new job and this weeken I work 7am to 2pm then 3-6 then that night 9-9:30. And today I worked 7am to 11am then came back at 2:30 and left at 6:30 now I go back at 9pm and then I work in the morning at 7am. I have got better at my job but this weeken was HORRIBLE for me and it did not make it any better than my coworkers were not very kind and I'm very stressed. Somehow I manged to lock my keys three times in my car and this HARDLY ever happens to me. I'm upset and I need to calm down so mom told me to find out how much it cost for another key.

I have my key so how much will it cost for Ford to make two copies of it? I really hope it is not pricey but I really need it just encase.

I know I need to relax… I'm 22… There's no reason I should be so dang stressed and I'm trying anyway

anyone know how much it would cost? Thank you oh and it has the black thing at end of key if that matters…

Watch this video, he did his for $12 and then programmed it himself.

DO yall have an ace hardware around? I think it should be like $10
