Kangaxx mod? Can't move sarcophagus

Hey guys,

I'm playing BG2EE with a lot of mods and was trying to do the "Restore Kangaxx Body" quest. But I can't open the sarcophagus beneath the temple district or at the Bridge District... It says
"... The lid of the Sarcophagus bears a circular socket and seems utterly unmovable."

Any ideas where I can find the keys (or whatever) to open them?
