Questions about locksmith service costs

What is a good rate to open a doorknob in the NYC area? Are prices higher for “commercial” grade doorknobs? This was just a doorknob with a keyhole inside that was a higher quality weight/material. First locksmith quoted a charge of $150 and the second changed his $125 quote to $225 after saying it was “commercial”. He opened it in 5 minutes by drilling out the keyhole. (I was in a rush). In retrospect, I feel I was ripped off.
