Is the transaction confirmed? If it is confirmed, you cannot attempt to double-spend it.

If it is unconfirmed, then you can attempt to double-spend it.

What wallet did you use to send the original transaction?

Depends on what you want to achieve. If you want to invalidate that transaction, just use any of the input and create a new transaction.

If you want to spend both the inputs to a different address, you will have to craft a transaction with both of the inputs in the transaction. You have to use both of the private keys to sign or it won't be valid.

There is one fill for Private key.

Sign with one of the key first. Next, copy the signed raw transaction, and do the same with the second private key.

For the second time, the raw transaction has to be signed with the first private key first.
