It might be easiest to cancel and set the new one up on PayPal. As long as you strictly control where you use it, PayPal has been pretty secure.
My bank has free "bill pay" which has been 100% secure for me. The payment is deducted from you savings/checking account, the bank prints the check and mails it for you w/ no additional charge. You can also set up ACL direct transfers for things like cable bills and mortgage payments that repeat a fixed amount at regular intervals. If you have direct deposit your life just keeps on rolling even if you drop dead.
