omg, ask a locksmith . and why would anyone ever go to homedepot for any type of keys/locks/etc. we use to be able to do them here (security lock & safe) but our machine is down. go to lockman, just east of 66 on park blvd on the south side of the street. they might even be able to program it depending on year etc. if you have the blank there pretty reasonable, however i can't quote a price for them.
