Quote from : Terminator 2: Judgment Day Movie

Miles Dyson: [after swiping his card on a control panel, nothing happens] My card should access this thing.
[swipes his card several times more, nothing happens, then he tries to open it up with his hand]
Sarah Connor: What happened?
Miles Dyson: Dammit.
[checks the map screen and finds out what is going on]
Miles Dyson: The silent alarm is tripped. All of the codes are neutralized in the entire building, nothing will open anywhere now. We have to abort.
Sarah Connor: [gets in front of Dyson] No. We'll go all the way.
