Black and white movie-- probably from the 50s, and MGM. Group of about 5 men and a woman try to break into an armored car. The guards inside activate the metal shutters. I believe the crooks load the car into a semi, and take it to a secluded shed, to endeavor to break into it. One by one, the people are killed trying to break in.. By the guards inside. . Finally there are just 2 guys and a woman left. The guy manages to break into the front door. The guard is slummped over the wheel, but was just faking his death. He shoots another, before being shot himself. In the end, the last guy tries to escape, when the shed is surrounded by police. He climbs to the top of this hill, but I think he is shot.. . And no.. The movie isn't "They came to rob Las Vegas"
