Char wants to go into the Electro Shock Room. But it's locked!

Hint 1 of 8:

You've tried all they combinations on the lock.

Hint 2 of 8:

Are you sure?

Hint 3 of 8:

Maybe they changed the combination while you were trying.

Hint 4 of 8:

Isn't it much easier in the movies where they either shoot a lock or burn
it with some electrical wire?

Hint 5 of 8:

No, the microphone cable will not be able to handle the sudden rush of
electrical current needed to destroy the lock.

Hint 6 of 8:

Bad memories about Shablee prevent you from looking for a suitable
electrical cord? Trust me, HE won't be there.

Hint 7 of 8:

The same insulation that protects you from electrocuting yourself also
prevents electricity from flowing from the end of the electrical cord into
the lock.
