Lock Lane became the second local amateur side to reach the Ladbrokes Challenge Cup fourth round.
They won 37-22 at League One Oxford on Sunday to emulate Featherstone Lions who beat South Wales Scopions 37-20 on Saturday.
Lane led 25-12 at half-time and never looked like relinquishing their grip in the second-half.
Their try scorers were Adam Garlick (two), Royce Geoffrey, Calum Butler, Nathan Fozzard, Danny Rowse and Nicky Saxton.
The fourth round draw is on Tuesday evening.
Joining the successful teams from this weekend’s third round fixtures will be all 12 Kingstone Press Championship clubs.
Fourth round ties will be played over the weekend of March 19-20.
