Seattle Lock & Doors sent their technician to my house to rekey the lock because I lost my key at the shopping center. Roy the technician showed up on time and I showed him all the locks locations need to rekey but he found my keychain in the side door when he walked in the house, I was so embarrassed. He offered to waive the service call and that was so nice of hem but for sure I would use hem again when I need a locksmith.
