Sevan Locks was one of the few locksmith services I called when I moved into a new place in Seattle. They did have the highest rating and the best quote to replace my locks among the few I called so I made an appointment to have my locks changed with them.
The locksmith arrived within the scheduled window (2 hrs) and worked quickly. He was done in about 30 minutes. I would recommend calling ahead to get the pricing figured out, my locksmith had given me a different price on the receipt, but I mentioned my phone quote was a different price. He honored the price I received on the phone. I would work with and refer this company to anyone.
