yup, did exactly what you said, pried that sucker open with minimal force. Thanks!That's how they all are. You need to remove the key blade if it's not already cracked and falling out. My favorite method is pliers grabbing right near your thumb in that picture. Grab the "ear" of the key blade with the pliers and rotate the blade right out. You can also cut it out with diagonal pliers.
If it gives you any hassle, let me know. I've got a good little video clip somewhere on facebook I can link you too. I need to get that uploaded as a YouTube video to help folks make that a quick task.
