The power steering is not related to the key cyliinder.
The tumblers inside the key cylinder must have jammed up, try rocking the key inside the cyliinder and see if you can get it working. If not, try using the original.
Get a locksmith to repair it even if it works for now.
As for the power steering, check the fluid level, if it is low due to any leaking, it will be stiff to operate.
