I've used Advanced Lock & Security several times before; and this time I had a door that wouldn't unlock. I wanted to use the same key for the new lock that they were going to make to fit my door and the results are good. It took them about a week to make. The company is very good about calling you back. They work with your schedule which is good since I like to be around anytime something is being done to my home. The technicians are professional and very good; I believe its a skill that you can't just get any ol Joe Blow to the job, so, their technicians are very competent in this area. Prices are reasonable.
