hey friend i was facing the same problem about i cant trust anybody to make locks for my office. i was looking for a digital lock system and i cannot give this assignment to any one else because i cant jus trust them. then i met with one of the worker of Locksmith Service and i found him working in next door i talked to him and he was so friendly then i asked from the owner of the house about this company and he told me tht you can trust them tht they can work by keeping the privacy in view. so i tried them and they are so trust worthy. tht is y i recomend you to use them for making locks of your flats.
