Emergency call late on a Saturday night. Deadbolt mechanism broke inside lock/could not enter our home. website said $15 service call/24 hr emerg service. Technician arrived after we waited about 1 1/2 hrs as tech went to right address in WRONG city despite very clear instructions of where we were located. got same story about having to drill out "high security lock". had to replace the lock, made a huge mess and then told us we had to pay him $750!! We felt VERY taken advantage of but also had few options in the middle of the night. No receipt provided by tech. said office would email. they never did. will never call them again. time will tell if it was a good job or not. I suspect not.
