A vault purportedly containing unreleased Prince songs was drilled open, according to ABC News affiliate KSTP-TV.
The singer, who released 39 studio albums and dozens of other musical projects, died April 21 at his Paisley Park home in Chanhassen, Minnesota. He was 57.
Bremer Trust, the St. Cloud, Minnesota, company given temporary authority over Prince's estate, opened the vault to which only Prince had the code, KSTP-TV added.
Previously, Prince spoke openly about his treasure trove of music on "The View."
"One day, someone will release them. I don't know that I'll get to release them," he said back in 2012. "There's just so many."
The seven-time Grammy Award winner reportedly left behind a vault containing so much music his estate could put out an album a year for the next century.
"We could put out more work in a month than most people could do in a year or more," Susan Rogers, Prince's former recording engineer, told ABC's "Good Morning America."
Rogers added that the vault in Prince's Paisley Park home was a giant room with shelves that filled up quickly. The door to the vault was sealed with a large spinning wheel.
The news of Prince's vault being opened comes as his sister, Tyka Nelson, claimed earlier this week that the singer had no will or trust, according to paperwork she filed in Minneapolis.
The documents obtained by ABC News, signed by Nelson, state, "I do not know of the existence of a will and have no reason to believe that the decedent executed testamentary documents in any form."
State law says that if Prince didn't have a will or trust, his estate is set to be divided between Nelson and his five half-siblings.
