Lost key how do i hotwire 2010 ford focus

The only wire that will work is your wire-less phone. Use it to call a good automotive locksmith and make sure you have all the documentation to prove that you own the car. Ford can make you a key if you give them the VIN # but it may be very pricy

You don't....

Any car can be hot wired. However, nobody is going to tell you how to do it for obvious reasons. Also, if you're having to ask, you don't want to bother as you'll likely electrocute yourself in the process. Tom had the best advice: call a locksmith and get Ford to make you a new key. Even if you hot wire the car, do you plan on doing that forever to crank it?
