Let's get down to brass tacks. I need to hack both the vault room computers to get control of the electronic winch above the ballroom.
― Bentley, explaining his part in the mission[src]
After Sly crawled into the boardroom, he needed to open the vault room from the inside to let in Bentley and Murray. The password was written under one of the four breaktables so that the guards could not forget it. Sly crawled underneath each one, looking for the code and using them to hide from the roaming flashlight guards. While he did so, Rajan addressed his men over the loudspeaker to remind them not to allow any trespassers into the inner workings of his palace.
Once Sly found the code, which was "46583271," he gained access to the vault room and pulled the security lockdown switch, which unlatched a door upstairs, allowing entry for Bentley and Murray. Once Sly joined them on the top section, Bentley reminded them that he needed to hack both of the security terminals in order to get control of the electronic winch above the ballroom, but warned that guards be onto them and required protection from them both.
Bentley began hacking through the level six barrier and was immediately onset by guards.[notes 1] Sly and Murray defended him as he switched back and forth between the two terminals, eventually hacking through all six barriers and gaining control of the winch. Once they hooked up the direct feed, the gang left the room while the coast was clear.
