Desealing rod
From Memory Alpha, the free Star Trek reference.
A desealing rod is a small, hand-held tool used to open locks and deseal doors.
In 2370, Rom used a desealing rod that Nog made to break into the ship's store on Deep Space 9 and retrieve a strongbox hidden by Vaatrik during the Cardassian Occupation of Bajor. Rom was able to deseal the door in less than ten seconds. (DS9: "Necessary Evil")
