The metal door to the Wargrave Vault worked almost the same way as the doors at the Wargrave Training Facility. The indestructible metal doors at the Training Facility only required a Wargrave to project their Will and DNA, and they would open.
But these Wargrave Vault doors didn't require Will, only DNA... well, according to the information they had acquired over the years.
And with only DNA being required, the Sinvairas were adequately prepared. They already had the DNA of an Emperor, so obtaining the DNA of a Wargrave wasn't anything outrageous.

They could also have simply taken it from Nazark's corpse after killing him.
