Perry Hall Locksmith are thieves - don't use them, there are numerous other locksmiths in the same area. They will quote you a price on the phone and then charge you more than double when they come out AFTER they have completed the work, so you don't have a choice. They told me over the phone the fee to change a mailbox lock would cost approximately $55 including the service call, new lock, & 2 keys. They did not mention any other charges. The entire job took 15 minutes, and the technician charged me $189 for a MAILBOX lock that is tiny, maybe 1" diameter. I called their customer service department to ask about the excessive fee and why it wasn't mentioned to me when I placed the service call, and they could care less and were very rude. GO ELSEWHERE before you get ripped off.
