Friend of mine had locked keys in car. He got a replacement at Harvey toyota for 10 dollars. They are great people to deal with.
You can get a replacement but price is determined by the dealer.
Depends on the key. If it has a chip it can be over a hundred dollars at a dealer. As for what you need, if you have another key you can get that copied almost any hardware store. If you don't have another, then a locksmith can help. Going to a dealership is going to cost more.
Go to Wal-Mart. They do keys.
