I called to have the door of one of our interior offices opened(locked in error) I called David’s Lock Service I was told about $ 50 on the phone When the guy got to the office he wanted to charge $ 175 just to open the door. Required I pay the service fee of $ 29 just for them to do nothing. Not worth using… I also found out David’s Emergency Lock Service does not have a registered license with DPS. Complete rip off Do not USE!!!
