You should contact the transportation department for the city where the parking meter is located. They will be able to transfer you to the parking authority, who should have the keys to the parking meter.

If the meter is broken you are not supposed to park there.... you can get a ticket for parking at a defected meter.

No, but I am sure if you tried to die a giraffe to a parking meter, you would be asked to move it.

The world's first installed parking meter was in Oklahoma City, Oklahoma, on July 16, 1935
