You mentioned a very important point. setMethod() - function of opcheckout.js has to be fixed too. Otherwise the customer password is not correctly stored.

Hi - I get the same problem as redtennis above:

getting an error after executing add-checkout-form-key.sh
sed: no input files

Any ideas?

open your custom theme payment.phtml file
app/design/frontend/custompackage/customtheme/template/checkout/onepage/payment.phtml

cut the below code from 'co-payment-form'
<?php echo $this->getBlockHtml("formkey") ?>

and paste it above 'co-payment-form' form tag like

<?php echo $this->getBlockHtml("formkey") ?>
<form id='co-payment-form'>

This thing resolved my issue.

@umeshtandel

<?php echo $this->getBlockHtml("formkey") ?> should put under <form id='co-payment-form'> , not above. Otherwise it will not work.

It should like:

<form id='co-payment-form' action="">
<?php echo $this->getBlockHtml("formkey") ?>
