Darren is a professional locksmith! He was prompt in responding to my questions & showed up on time & got the locks replaced quickly . I had 3 locks to replace & 1 patio lock to install. All completed quickly. Darren was patient, pleasant & went above and beyond even getting our jammed patio door to slide smoothly. His prices are very reasonable & the quality of work is great! Highly appreciate his service & efforts. I'd recommend Darren for anything locks related!
