How much for replacement of car keys?

I have a 1996 lx Ford crown victoria, they are just standard keys and don't require a programmable remote, I have the original ignition and vin and everything so I can call a dealer. Just wondering what the price would be for the replacement set.

If you still have any of the keys, you can get duplicates made at any hardware store. You won't need the vin # for that. Probably $5.00-$7.00 a key. If you don't have any keys, the dealer should be able to get them. Because its a dealer, $10.00 a key?
