Bank Heist Movie

Hi guys, I'm trying to find a movie about a bank heist. The only bit about it that i do remember is they try to keep setting the banks alarm off with some sort of remote control vehicle/device. Its got to be at least 20-30 years since it was released and i don't recall if the main robber was a man or a woman.

The word is Banana Muffin.

Did they do it to mask their entry into the building or to cause the security team to think the alarm system was going haywire? If so, I thought it was something like a fast remote control car.

I think it was to make the alarm system go haywire so the authorities would turn it off making it much easier for the robbers to break in downstairs while authorities who are tasked to watch the place are upstairs. Im not sure what device they use tho to keep setting off the alarm as i think it [the alarm] was motion sensitive.
