It wouldn't if that was all you were going to do, however under the
circumstances, she needs to check the crankshaft and blade keys as well

How did you determine that the timing key is sheared? Have you determined
that the crank shaft is not bent? Two things to do before you start to
dismantle a mower. Remove the spark plug and drain the oil. The first is
for
safety and the second is because you'll wish you did

Why would draining the oil be needed to replace the flywheel key? You
don't
even need to tip the machine.
