Car was locked on the college avenue

I parked my car at the street parking lot at downtown. From 1:30 - 5:30pm. I pay the meter every 2 hours I don’t know why it was locked. The trouble thing is that the borough office is closed right now and I need to drive my car to home! They also charge me the 100 boot fee. So stupid! I don’t know how to solve this😂😂
