Help! My Key Fob Hardware is Breaking

In the first picture above, part of the handle sits   on top  of the die.  (This is exaggerated for demonstration purposes.)  As a result, the dies will bend the handle when pressed down, thereby causing the handle to break off.

 

In the second photo above, only the   opening  of the "V" part of the hardware is sandwiched between the dies.  The top part of the "V" where the handle connects   doesn't touch  the dies at all.  This ensures that the handle won't be crushed when pressure is applied.

 

Tip: When using the table press with the key fob clamping dies, it's best to apply light pressure and press down only partially on one side of the hardware first.  Then flip the hardware and press down a little more on the other side.  Repeat.  This results in more even pressure being applied to both sides of the hardware for a more uniform press, and helps to prevent over-pressing which may cause the handle to break off.
