The solution won't be a new ignition switch at all, it will be sending additional detachable key rings to owners (allowing drivers to disconnect their car key from the rest of their key chain to reduce strain on the system) and/or inserts designed to fit within the ignition key head itself to alter the keyring attachment loop from a slot to a hole (because the slot can cause the weight of the keychain to hang asymmetrically, thereby increasing the amount of torque on the key and as a result, the switch.
I do not understand the second solution (more like a band aid).
